## Introduction

Welcome to the Audio Mixing Masterclass with Luigi Giraldo, who has worked with industry giants such as RedOne, Lady Gaga, Enrique Iglesias, and Jennifer Lopez. This comprehensive guide will take you through the essentials of professional audio mixing, from instrument-specific techniques to advanced automation and video sync workflows.

## Module 7: Getting Into The Mix (Part B)

### 7.1 Keyboards

Keyboards, synthesizers, and samplers offer an endless palette of sounds with unique freedom of creation and character. Here's how to approach mixing them effectively:

#### General Considerations

- **Placement**: Position keyboards in the mix to avoid masking other elements or being masked
- **Masking**: Occurs when two elements use the same frequencies simultaneously, making one less audible
- **Solution**: Move elements to different positions in the stereo field or mute one when necessary

#### EQ Guidelines

- **High-Pass Filter**: Set before the key frequency of the song, typically nothing below 100Hz
- **Low-Pass Filter**: Set around 10,000Hz to create space for hi-hats, overheads, and cymbals
- **Clean Low End**: Cut unnecessary low frequencies, especially for keyboards panned to the sides

#### Compression Settings

- **Attack**: 25-60ms depending on the song's BPM
- **Release**: 50-120ms, adjusted according to the tempo
- **Ratio**: 2.5:1
- **Amount**: Usually no more than 2dB
- **Velocity**: When programming keyboards, compress the velocity range for more controlled dynamics

#### Reverb Approach

- **Timing**: Wait until the end of the mix to decide if keyboards need reverb
- **Recording**: Record keyboards dry (without reverb/delay) whenever possible
- **Coherence**: Maintain consistent reverb spaces across instruments
- **Tempo Sync**: Ensure delays match the song's BPM

#### Types of Synthesizers and Their Treatment

**Lead Synths**:
- **Placement**: Center of the mix as the focal point
- **Frequency Range**: Usually play parts above the chords (octaves 5-7)
- **High-Pass Filter**: Around 80-110Hz depending on the key
- **Low-Pass Filter**: Around 12,000Hz
- **Compression**: 2-4dB with ratio between 2:1 and 5:1
- **Reverb**: Can sound great with the main reverb for spaciousness

**Saw Synths**:
- **Placement**: Center when playing main chords; sides for shorter instances
- **High-Pass Filter**: Before key frequency, at least 100Hz
- **Low-Pass Filter**: 10,000-14,000Hz to prevent cluttering high frequencies
- **Compression**: Up to 3dB with ratio of 2:1 to 5:1
- **Reverb**: Be cautious as they have a wide frequency range

**Pluck Synths**:
- **Placement**: Work well on the sides of the mixing space
- **High-Pass Filter**: 180Hz to 1kHz
- **Low-Pass Filter**: Around 12,000Hz
- **Compression**: 2-3dB with ratio of 2:1 to 5:1
- **Attack**: 20-40ms to enhance punch
- **Release**: 35-100ms
- **Reverb**: Shine with creative reverb treatments

**Atmospheric Synths**:
- **Wide Frequency Range**: Careful not to clutter the mix
- **High-Pass Filter**: Remove unnecessary lows for a lighter sound
- **Stereo Management**: Consider mono-izing low frequencies below 100Hz
- **Compression**: Very subtle with soft knee and low ratio (2:1)
- **Reverb**: Often create their own sense of space without needing additional reverb

**Sound Effects**:
- Treat similarly to synthesizers
- Avoid panning low-frequency effects
- Use reverb sparingly

### 7.2 Strings

Approach mixing strings by considering whether they're synthesized or real (sampled or recorded).

#### Synthesized Strings
- **Placement**: Sound great to the sides if they don't have much low frequency content
- **Low Cut**: Between 100-500Hz to open space for other elements
- **High Cut**: Around 12,000Hz for hi-hat and cymbal space
- **Distance Effect**: Lower the low-pass filter to make strings appear further away

#### Real Strings
- **Placement**: Follow traditional orchestra seating
  - First Violins: 9-10 o'clock position
  - Second Violins: 10-11 o'clock
  - Violas: 11-1 o'clock
  - Cellos/Double Basses: 1-3 o'clock
- **Depth Perception**: Reduce high frequencies slightly for instruments that should appear further back

#### EQ and Processing
- **Low End**: Don't add low frequencies as they make everything sound muddy
- **Brightening**: If needed, boost between 6,000-10,000Hz
- **Rule of Thumb**: "Less is better than more" - instead of boosting highs, consider cutting lows
- **Mix Space**: Adjust placement if working with other instruments

#### Compression
- **Approach**: Very light compression with subtle settings
- **Ratio**: 1.5:1 to 2.5:1 with soft knee
- **Attack**: 40-80ms
- **Release**: Long
- **Amount**: No more than 2-2.5dB
- **Alternative**: Use automation rather than compression for dynamic control

#### Reverb
- **Timing**: Add reverb at the end of mixing when all elements are placed
- **Mix Density**: The emptier the mix, the more effects you can use
- **Placement**: Maintain consistent reverb spaces based on instrument position

### 7.3 Brass

Brass instruments require specific treatment based on the style of music.

#### Placement by Style
- **Classical**: Behind strings (trumpets, trombones, tuba, horns)
- **Jazz/Big Band**: Specific layouts following traditional formations
- **Pop**: More flexible arrangements depending on instrumentation

#### EQ Approach
- **High-Pass Filter**: Before the key frequency of the horns
- **Low-Pass Filter**: Around 10,000Hz to maintain brightness while saving space
- **Subtle Boost**: If needed, 200-350Hz for body (0.5-1dB)
- **Brightness**: 6,000-9,000Hz if recording quality needs enhancement

#### Compression
- **Light Touch**: Very delicate compression to maintain expressiveness
- **Ratio**: 1.5:1 to 2.5:1 with soft knee
- **Attack**: 30-40ms
- **Release**: 60-130ms
- **Amount**: No more than 2-2.5dB
- **Alternative**: Use fader automation for level control rather than heavy compression

#### Reverb Treatment
- **Low End**: Cut low frequencies from the reverb return
- **Timing**: Add reverb after all elements are properly placed and leveled
- **Brightness**: Keep reverb bright enough to blend with the brass tone

### 7.4 Woodwinds

Woodwind instruments require a more delicate approach to EQ and dynamics processing.

#### Instrument Range
- **Instruments**: Piccolo, flutes, oboe, English horn, clarinets, bassoon, contrabassoon
- **Frequency Range**: Relatively narrow ranges make them easier to place in the mix
- **Placement**: In front of brass but behind strings in the orchestral layout

#### Processing
- **EQ**: Remove low frequencies according to each instrument's range
- **Compression**: Very delicate to maintain dynamics and character
- **Fingerwork**: Preserve the percussive quality created by fingering techniques
- **Reverb**: Long pre-delay for an "in-your-face" sound
- **Depth**: Reduce high end slightly to create the illusion of depth

### 7.5 Vocals

Vocals are the most critical and challenging element to mix effectively.

#### Fundamental Approach
- **Priority**: Bring vocals early into your mix
- **Context**: Process vocals within the track, not in solo
- **Monitoring**: Resist the urge to use the solo button

#### Processing Chain
1. **Console Emulation**: Add subtle harmonic distortion
2. **Light Compression**: First stage to gently control dynamics
3. **EQ**: Cut around 160Hz and boost at 8kHz and 16kHz for clarity and air
4. **Multiband Compression**: Add body where needed in different frequency ranges
5. **De-esser**: Control sibilance (use Fat Filter, Mac DSP, or dbx 902)
6. **Second Compression**: 1176-style for more dynamic control
7. **Final EQ**: Add low end if needed (around 100Hz)

#### Reverb Techniques
- **Pre-delay**: Open up pre-delay to separate direct sound from reverb
- **Ducking Reverb**: Side-chain the vocal to the reverb to reduce reverb while singing
  - Set up: Send vocal to compressor side-chain on reverb return
  - Threshold: Adjust until reverb reduces during vocals
  - Ratio: 4:1 is typically good
  - Attack/Release: Set release to be musical with the tempo

#### Vocal Doubling
- **Plugin Method**: Use doubling plugins like Waves Doubler
- **Dedicated Software**: Use Synchro Arts Revoice Pro or VocalAlign
- **Panning**: Place doubles on sides for width
- **Processing**: Make backgrounds slightly darker than lead vocals

#### Cleaning Vocals
- **Option 1**: Noise gate (not ideal for expressive vocals)
- **Option 2**: Manual editing (time-consuming but precise)
- **Option 3**: Automation of mute button (most musical approach)

#### Automation
- Don't rely solely on compression; use volume automation for detailed control
- Automate EQ, sends, and panning when appropriate

## Module 8: Working With Video

### 8.1 Working with Video

Audio mixing for film or television involves combining recorded sounds during the post-production stage, manipulating signal levels, frequency content, dynamics, and panoramic position.

#### Four Key Audio Elements in Film/TV Mixing

1. **Speech/Dialogue**:
   - Characters speaking (to each other or alone)
   - Consider the acoustic environment of the scene
   - ADR (Automated Dialogue Replacement): Re-recording dialogue to replace problematic original recordings
   - Voiceover: Off-camera commentary narrating what's happening on screen

2. **Ambience/Atmosphere**:
   - Background sounds of a location or space
   - Prevents total silence
   - Examples: coffee shop sounds, street noise, ocean waves, etc.

3. **Sound Effects**:
   - Artificially created or enhanced sounds
   - Two types:
     - Impact/emotional effects (booms, explosions)
     - Foley: Recreation of everyday sounds (footsteps, door closing, keys, car ignition)

4. **Music/Soundtrack**:
   - Usually pre-mixed by composer and music producer
   - Occasionally provided as multi-tracks for the mixer to blend

### 8.2 Diegetic and Non-Diegetic Sounds

Understanding the distinction between sounds that exist within the story world versus those added for audience effect.

#### Diegetic Sound
- **Definition**: Sounds that characters can hear as well as the audience
- **Characteristics**: Implies reaction from characters
- **Examples**:
  - Character voices
  - Object sounds (heartbeats, utensils, knocking)
  - Music from sources within the scene (TV, radio, concert)
  - Natural sound effects (dog barking, car passing)

#### Non-Diegetic Sound
- **Definition**: Sounds coming from outside the story space
- **Characteristics**: Not visible on screen, no implied action in the story
- **Examples**:
  - Sound effects added for dramatic impact
  - Commentary voice/narration
  - Mood music or film score
- **Role**: Creates atmosphere and mood, can indicate shifting between scenes

### 8.3 Sync: SMPTE, MTC and MIDI Clock

Understanding synchronization protocols is essential for audio-visual work.

#### SMPTE Time Code
- **Definition**: Standard for labeling individual frames of video/film with timecode
- **Format**: Contains hours, minutes, seconds, and frame identifications
- **Frame Rates**:
  - 24 fps: Film, 2K, 4K, 6K
  - 25 fps: PAL system (Europe, Uruguay, Argentina, Australia)
  - 29.97 fps: NTSC system (USA, Canada, Mexico, Colombia)
  - 30 fps: Used in some applications
- **Usage**: Provides time reference for editing, synchronization, and identification

#### MIDI Time Code (MTC)
- **Characteristics**: Embeds SMPTE time information as MIDI messages
- **Data Flow**: Quarter frame messages transmitted in sequence of eight messages
- **Best Practice**: Use separate MIDI port for MTC to avoid jitter
- **Limitation**: Not tempo-dependent

#### MIDI Clock
- **Definition**: Clock signal broadcast via MIDI to keep devices in sync
- **Characteristics**: Tempo-dependent (unlike MTC)
- **Rate**: 24 pulses per quarter note (PPQN)
- **Usage**: Maintains synchronized tempo for arpeggiators and tempo-dependent effects

#### Choosing the Right Protocol
- **SMPTE**: Audio standard, travels through audio connection
- **MTC/MIDI Clock**: Travel through MIDI cables or network cables
- **Considerations**: Different applications may work better with different sync methods

### 8.4 Video Playback

There are three primary methods for working with video while mixing audio.

#### Method 1: Video Within DAW

#### Connection Methods

1. **Using MIDI Time Code (MTC)**:
   - Create a virtual MIDI port (IAC driver on Mac)
   - Set Pro Tools to generate MTC through the virtual port
   - Set secondary software to follow MTC
   - Ensure both applications use the same SMPTE frame rate
   - Consider matching BPM and sample rates manually

2. **Using ReWire**:
   - Open Ableton Live or another ReWire-capable application
   - Create instrument track in Pro Tools
   - Select the ReWire application as the instrument
   - Play from either application to control both
   - Advantage: BPM changes are automatically synchronized

#### Limitations
- MTC only provides start/stop, not scrubbing
- Slight delay in synchronization
- ReWire requires both applications on the same computer

### 8.6 Video Playback Outside the DAW using 2 Computers

For professional setups, using two computers offers the best performance.

#### Connection Methods

1. **MIDI Connection**:
   - Each computer needs a MIDI interface
   - Connect MIDI OUT from one to MIDI IN on the other
   - For SMPTE, use interfaces with SMPTE-to-MTC conversion (MOTU MIDI Express XT, E-Magic Unitor 8)
   - Alternative: Network MIDI connection

2. **Video Satellite Link (Pro Tools)**:
   - Requires one HDX system (administrator) and other Pro Tools systems
   - Set up satellite mode in peripherals settings
   - Allows up to 12 systems with sample-accurate sync
   - Enables scrubbing across systems
   - Limitation: Control only from master system

3. **VST System Link (Steinberg)**:
   - Works with Cubase Pro or Nuendo
   - Requires digital audio connection between interfaces (ADAT/Lightpipe)
   - Set same sample rate and bit depth on both systems
   - Enable BST System Link and specify I/O routing
   - Allows control from either system
   - Supports recording across systems

#### Best Practices
- Match sample rates and frame rates across systems
- Use dedicated audio/MIDI connections
- For film work, Steinberg's solution offers excellent flexibility

### 8.7 Introduction to Surround

Surround sound enhances audio reproduction by adding channels that surround the listener.

#### Basic Concepts
- **Definition**: Technique to enhance sound quality with additional audio channels
- **History**: Dating back to 1940s (Disney's Fantasia), but popularized with DVD and digital movies
- **Market Adoption**: Strong in film/TV, limited in music industry

#### Surround Formats
- **5.1**: Five speakers + LFE (subwoofer)
- **5.0**: 5.1 without subwoofer
- **6.1**: Adds rear center channel
- **7.2**: Standard 7.1 with two LFE channels
- **10.2**: Adds height dimension with overhead speakers

#### Setting Up for Surround
- **Speaker Placement**:
  - L/R front speakers (as in stereo)
  - Center speaker
  - L/R rear speakers
  - LFE (can be placed anywhere)
- **Interface Requirements**: Minimum six physical outputs
- **Channel Configuration**: Depends on your interface and DAW

#### Mixing Considerations
- **Source Material**: Easier to mix with mono sources
- **Plugins**: Need surround-compatible versions
- **Dynamic Processing**: Less compression needed due to spatial freedom
- **LFE Channel**: Used as auxiliary send for low frequencies
- **Reverb**: Create consistent spaces appropriate to the scene

## Module 9: Automation

### 9.1 Automation: What is it?

Automation allows the DAW or console to remember all movements made during the mix process.

#### Historical Context
- **Pre-Automation**: Multiple engineers manually adjusting faders on cue
- **First Methods**: Recording separate bounces to an 8-track cassette
- **VCA Automation**: Fader levels regulated by voltage control amplifier
- **Moving Fader Automation**: Motorized faders controlled by computer
- **Software Control**: Virtual faders with complete parameter control
- **MIDI Automation**: Using MIDI to send control messages

#### Importance
- Automation requires timecode to track elapsed time
- Enables complex, precise mixing impossible to do manually
- Essential for maintaining consistency across iterations

### 9.2 What can be Automated?

Nearly everything within a DAW session can be automated except solo switches and plugin activation/deactivation.

#### Automatable Parameters
- **Audio Track Controls**:
  - Volume
  - Panning
  - Mute switches
- **Send Controls**:
  - Send volume
  - Send panning
  - Send mute
- **Plugin Parameters**: Any parameter in plugins/virtual instruments (if designed for automation)

#### Automation Properties
- **Behavior**: Functions like MIDI/audio data (can be deleted, copied, pasted)
- **Editing**: Can alter values for groups, redraw, copy between tracks
- **Control**: Enable/disable automation writing for different parameters
- **Plugin Automation**: Access via automation menu or Ctrl+Option+Command+click (Mac)

### 9.3 Automation Modes: Manual Write and Write on Stop

Different automation modes determine how your DAW behaves when writing or reading automation.

#### Basic Modes
1. **Off**: Ignores all automation
2. **Read**: Plays back existing automation without allowing changes
3. **Write**: Records absolute position of enabled parameters, erasing previous automation
4. **Latch**: Reads existing automation, starts writing when you touch a control, continues writing until stopped
5. **Touch**: Reads existing automation, writes while touching controls, returns to previous automation when released
6. **Touch/Latch**: Volume faders in Touch mode, everything else in Latch mode

#### Manual Write Options
- **To Start**: Writes current value from current position to beginning
- **To Selection**: Writes current value to selected region
- **To End**: Writes current value from current position to end
- **To Punch**: Writes from current position to where you started changing the parameter
- **To Next Breakpoint**: Writes to the next automation point

#### Write on Stop
- Same functions as Manual Write but executes when playback stops
- Useful for quick edits without interrupting workflow

#### Latch Prime
- Allows writing automation without playing the session
- Useful for making quick changes to selected regions

### 9.4 Automation Trim

Trim automation allows you to edit existing automation curves without changing their shape.

#### Key Concepts
- **Function**: Allows offsetting existing automation by a relative amount
- **Visual Indicator**: Yellow light/line shows trim amount
- **Mathematical Relationship**: Trim values are added to/subtracted from original values
- **Applications**: Make global adjustments to already automated tracks

#### Coalescing Trim Automation
- **Definition**: Committing trim automation to the actual automation
- **Methods**:
  1. Using control surface (select track and press coalesce)
  2. Automatically after every pass (preference setting)
  3. When exiting trim mode (preference setting)
- **Visibility**: Yellow trim line merges with white automation line

### 9.5 Automation Sends

Automating sends creates more dynamic, interesting mixes with creative effects control.

#### Applications
1. **Selective Effect Application**:
   - Mute/unmute sends to apply effects only in specific sections
   - Control when delays or reverbs are active

2. **Parameter Changes**:
   - Automate delay tempo changes for different sections
   - Change reverb properties during specific moments

3. **Creative Techniques**:
   - "Swelling reverb": Gradually increase reverb send for dramatic effect
   - Mute vocal reverb for specific phrases to create intimacy
   - Create buildups and transitions

#### Implementation
- Access send automation like regular track automation
- Write mute automation to control when effects are heard
- Automate plugin parameters within the effect itself
- Chain automation effects for complex sound design

### 9.6 Automation: Draw vs Real Time

Two primary methods exist for creating automation: using controllers in real-time or drawing with a mouse.

#### Real-time Controller Input
- **Advantages**:
  - More musical feel for certain changes
  - Intuitive for performance-based adjustments
  - Natural for DJs and performers used to hands-on control
- **Process**:
  - Can use hardware controllers or MIDI-learned parameters
  - Records exact movements as they happen

#### Drawing Automation
- **Advantages**:
  - More precise control for specific changes
  - Easier for mathematical/timed changes
  - Better for fade-ins/outs and specific transitions
- **Techniques**:
  - Square tool: Creates on/off steps (great for mutes/choppy effects)
  - Triangle tool: Creates cyclic panning or parameter changes
  - Line tool: Creates smooth transitions

#### Best Practices
- Use drawing for precise, timed changes
- Use real-time for expressive, musical changes
- Don't create fade-outs on master bus when using mastering compression
- Edit automation points as needed after recording them
- Use grid snapping for rhythmic effects

### 9.7 VCA Automation and Coalesce

VCA (Voltage-Controlled Amplifier) automation allows controlling groups of tracks while maintaining their relative balance.

#### Key Concepts
- **Group Control**: VCA masters affect all tracks in their group
- **Visual Representation**: Blue automation line shows VCA influence on tracks
- **Relationship**: Original track automation + VCA automation = actual level

#### Working with VCA Automation
- **Setup**: Create VCA masters for different instrument groups
- **Automation Writing**: Changes to VCA affect all tracks in group
- **Viewing**: Both track automation (white) and VCA influence (blue) visible
- **Practical Use**: Make broad mix changes while maintaining internal balance

#### Coalescing VCA Automation
- **Definition**: Writing VCA automation into individual tracks
- **Process**: Select tracks, use coalesce function
- **Result**: VCA returns to unity (0dB), changes become part of track automation
- **Benefit**: Simplifies automation view, maintains changes if VCA is removed

### 9.8 Automation Preview

A powerful feature in Pro Tools and Nuendo that allows testing parameter changes before committing them.

#### Function and Process
- **Definition**: Set parameters, test them in a loop, then commit only changed parameters
- **Workflow**:
  1. Enter Preview mode
  2. Make adjustments to desired parameters
  3. Only touched parameters are affected
  4. Capture settings when satisfied
  5. Write automation to selected region

#### Benefits
- **Efficiency**: Save settings for reuse in similar scenes
- **Non-destructive**: Test changes without affecting the mix
- **Precision**: Apply exact same settings to multiple regions
- **Consistency**: Maintain identical processing across similar elements

#### Applications
- **Film/TV**: Apply consistent processing to recurring scenes
- **Multiple Changes**: Adjust many parameters simultaneously
- **Complex Scenes**: Create specific sonic environments

### 9.9 Automation Snapshots

Taking the preview concept further, snapshots save multiple different parameter configurations.

#### Functionality
- **Definition**: Save up to 48 different parameter states/scenes
- **Requirements**: Control surface (including iPad with Pro Tools Control app)
- **Process**:
  1. Enter Preview mode
  2. Make adjustments
  3. Capture settings
  4. Save to snapshot slot
  5. Name appropriately

#### Applications
- **Scene Changes**: Apply consistent settings for recurring locations
- **Creative Exploration**: Save different mix versions
- **Efficient Workflow**: Instantly recall complex parameter combinations

#### Alternative Method ("Poor Man's Snapshots")
- **Manual Approach**: Without control surface
  1. Copy all automation for a section
  2. Create marker at end of song
  3. Paste automation there as reference
  4. Label clearly
- **Parameter Visibility**: Show all relevant parameters before copying
