Based on professional expertise from experienced composers, it provides detailed workflows, technical parameters, and practical approaches to achieve professional-quality audio deliverables. ## Table of Contents 1. Audio Monitoring Calibration 2. Stemming and Routing 3. Mixing Workflow 4. Level Management 5. Delivery Standards 6. Hardware Requirements --- ## 1. Audio Monitoring Calibration ### Setting Reference Levels Professional monitoring requires calibrated speakers to ensure consistent mixes across different environments. | Parameter | Recommended Value | Application/Notes | |-----------|-------------------|-------------------| | Reference Level | 75-85 dB SPL | Mid-range standard for film/TV mixing | | Target Level | 80 dB SPL | Optimal reference point | | Signal Type | Sine wave | For calibration purposes | | Signal Level | -6 to -10 dB | Just before entering yellow on meters | #### Process for Speaker Calibration: 1. Generate a sine wave test tone at -6 to -10 dB 2. Use an SPL meter (smartphone apps are acceptable) 3. Adjust speaker volume (not digital level) until meter reads 80 dB 4. Use this speaker setting for consistent monitoring > "I always shoot for 80 just kind of right in the middle of that range. I don't want to adjust the level inside my computer. I want to know that this level at unity is 80 dB coming out of my speakers." #### For Headphone Users: Direct SPL calibration isn't practical for headphones. Instead: - Compare your levels to commercial reference tracks - Maintain consistent headphone volume during production - Check mixes on calibrated speakers when possible --- ## 2. Stemming and Routing Stemming refers to separating your mix into component groups for final delivery, giving mixers flexibility to adjust elements independently. ### Standard Stem Configurations | Stem Type | Typical Contents | Purpose | |-----------|------------------|---------| | ORC (Orchestra) | Strings, orchestral elements | Main orchestral elements | | SYNTH | Synthesizers, electronic elements | Electronic textures and elements | | PERC (Percussion) | Drums, percussion instruments | Rhythmic elements | | KEYS | Piano, keyboard instruments | Melodic instruments | | GUITAR | Guitar tracks | String plucked instruments | | ELSE | Miscellaneous elements | Any other elements | ### Routing Methods #### Logic to Pro Tools Method ``` EN LA PRÁCTICA: Logic to Pro Tools Routing 1. Route instrument groups in Logic to specific outputs 2. These outputs feed into separate track inputs in Pro Tools 3. Apply stem-specific processing (reverbs, etc.) in Pro Tools 4. Record both individual stems and final mix simultaneously in real-time ``` #### DAW-Internal Rendering (Cubase) ``` EN LA PRÁCTICA: Cubase Offline Rendering 1. Select all groups/stems in the Audio Mixdown window 2. Enable "Effect Routing" to include reverbs in the stems 3. Process offline to generate all stems simultaneously 4. This allows for faster-than-real-time rendering ``` ### Stem Naming Conventions Proper naming ensures consistency and ease of use by mixing engineers: | Element | Example | Purpose | |---------|---------|---------| | Project Code | BHM | Abbreviation of project title | | Cue Number | M42 | Identifies specific cue | | Version | V1 | Tracks revisions | | Cue Name | End_Credits | Describes cue content | | Timecode | 01:23:45:00 | Starting timecode | | Stem Letter | A_ORC, B_SYNTH | Ensures stems stay in correct order | > "The reason that it's always a good idea to have a letter or number for your stems is because you might not necessarily go alphabetically with your stem names. So if you wanted to keep them in this order, that's why you would do A_ORC, B_SYNTH, C_PERC, because now they'll sort properly." ### Deciding What to Stem Stemming decisions should be based on: 1. Project requirements (some clients specify stem layouts) 2. Mix flexibility needs 3. Nature of the score (orchestral vs. hybrid) ``` FAQ: STEMMING Q: How many stems should I deliver? A: For TV/film work, 4-6 stereo stems is standard. Music mixers may want more detailed stems, while show mixers prefer fewer. Never deliver fewer than the client requests. Q: Should I separate orchestral instruments into individual stems? A: For show/film delivery, grouping orchestral elements (strings, brass, woodwinds) is common. However, keep strident or featured elements separate. Q: What elements should always be separated into their own stems? A: Any elements that might interfere with dialogue or sound effects, particularly percussive elements, "whooshes," or sound design elements that could be confused with sound effects. ``` --- ## 3. Mixing Workflow ### Approach to Mixing #### Starting Points When approaching a mix: 1. **Feature-First Method**: - Start with the most prominent/featured element - Get its level right, then build around it - This provides an anchor for your mix 2. **Bottom-Up Method**: - Start with bass elements - Build upward through the frequency spectrum - Ensures foundation is solid before adding higher elements #### Step-by-Step Mixing Process ``` EN LA PRÁCTICA: Efficient Mixing Workflow 1. Mute all tracks to start with a clean slate 2. Unmute and set levels for primary/featured elements 3. Bring in bass and foundational elements 4. Add midrange elements, adjusting to maintain clarity 5. Add high-frequency and percussive elements 6. Apply automation for dynamic changes throughout the cue 7. Consider dialogue when making EQ and level decisions ``` ### Time-Saving Techniques For tight deadlines, prioritize: 1. Feature element clarity 2. Dialogue intelligibility 3. Major volume automation 4. Proper stemming > "A lot of what I'm doing will be done on the fly. If I've got a piano melody, I'm mixing that where I want it, and then when I write the string part, I'm bringing that in to where it needs to be. My mix pass at the end is not going to be starting over and building it piece by piece—it's going to be little tweaks." ### Handling Arpeggiated Elements Arpeggiated or tempo-synced elements can be challenging to mix: | Issue | Solution | Benefit | |-------|----------|---------| | Timing errors when starting mid-cue | Freeze/bounce tracks to audio | Always plays correctly regardless of playback start point | | Volume consistency | Apply detailed automation | Maintains proper balance throughout | | Stemming placement | Route to appropriate stem based on character | Allows mixer to adjust with other similar elements | --- ## 4. Level Management ### Target Levels for Delivery | Meter Reading | Interpretation | Action | |---------------|----------------|--------| | Peaking at 0 dB | Too hot, risk of clipping | Reduce levels | | Consistently in yellow (-6 to -3 dB) | Good delivery level | Target this range | | Mostly in green (below -10 dB) | Too quiet | Increase levels | ### Balancing Music with Dialogue When mixing against dialogue: 1. Keep dialogue audible but mix music slightly hotter than it will be in final mix 2. Focus on frequency clarity rather than volume reduction 3. Communicate to clients that music will be louder in preview than final mix > "When I'm mixing my final cue, the music is generally going to be a little bit hotter than it's going to be in the final mix. I always point that out as a caveat too. I'll send them the preview and I'll say the music is mixed a little bit hotter than it will be just so you can hear everything and give me notes." ### EQ Considerations for Dialogue Clarity | Frequency Range | Typical Treatment | Purpose | |-----------------|-------------------|---------| | 200-500 Hz | Slight reduction | Reduces muddy frequencies that compete with male voices | | 1-3 kHz | Careful management | Critical dialogue intelligibility range | | 3-7 kHz | Controlled presence | Avoids competing with female voices and dialogue "presence" | ``` FAQ: LEVELS Q: How hot should I deliver my stems? A: Aim for peaks around -6 dB to -3 dB. This gives the mixer headroom while ensuring your music isn't too quiet to work with. Q: Should I compress my final mix before delivery? A: Light compression/limiting is acceptable, but don't over-compress. Most projects will have mastering applied later in the process. Q: How do I know if my music is competing too much with dialogue? A: If you can't clearly understand dialogue when your music is playing, consider reducing midrange frequencies rather than overall volume. ``` --- ## 5. Delivery Standards ### Final Delivery Package A complete delivery typically includes: | Component | Format | Purpose | |-----------|--------|---------| | Full Mix | WAV/AIFF, 48kHz/24-bit | Complete cue reference | | Individual Stems | WAV/AIFF, 48kHz/24-bit | Mixing flexibility | | Timecode Reference | Embedded or filename | Sync reference | | Naming Convention | Project-specific | Organization | ### Master vs. Slave Configuration When working with picture: 1. **Composition Phase**: DAW is master, sends timecode to video 2. **Delivery Phase**: Video/Pro Tools is master, DAW follows for recording ``` EN LA PRÁCTICA: Switching Between Master/Slave Modes 1. Composition: Set your DAW as master, sending MIDI timecode to Pro Tools 2. Video follows DAW timeline as you compose 3. For final render: Set Pro Tools as master, DAW as slave 4. Pro Tools controls timeline position, allowing simultaneous recording of all stems ``` ### Quality Control Checks Before delivery, verify: 1. All stems contain appropriate content 2. Levels are consistent across stems 3. No clipping or distortion 4. Proper sync with picture 5. No empty stems (redistribute if necessary) > "If I'm printing it and I see that one stem is completely empty, then that's an issue. I'll go back and I'll find something that I can separate onto that stem so that I'm as wide as I can possibly be." --- ## 6. Hardware Requirements Modern scoring requires substantial computing resources, particularly RAM. | System Component | Recommended Specs | Purpose | |-----------------|-------------------|---------| | RAM | 128GB minimum, 256GB ideal | Sample libraries, multiple DAWs | | CPU | 8+ cores | Processing audio and plugins | | Storage | 1TB+ SSD | Quick sample loading and recording | | Multiple displays | 2+ monitors | Efficient workflow | > "I've monitored my RAM and I don't think I've got me anywhere near even 256. I guess I was worried about having logic and pro tools going and sometimes live as well plus mail and which I know doesn't take up very much and Apple music and my web browser and stuff." ``` FAQ: HARDWARE Q: Mac vs PC for professional audio work? A: Both platforms are capable. Macs may handle RAM allocation more efficiently, while PCs often allow more cost-effective expansion. Q: How much RAM do I actually need? A: 128GB is comfortable for modern sample libraries with multiple DAWs running. Serious orchestral work may benefit from 256GB or more. Q: Should I prioritize CPU or RAM when building a system? A: RAM is typically the limiting factor for sample-based composition. However, a balanced system with both strong CPU and substantial RAM is ideal. ``` --- ## Pricing and Business Considerations While primarily a technical document, understanding payment standards is essential for professional work. ### Film & TV Project Fee Guidelines | Project Type | Fee Approach | Considerations | |--------------|--------------|----------------| | Studio TV | Fixed minimum rates | Negotiable upward based on experience | | Major Films | Budget percentage | Typically aim for 3% of total budget | | Independent Films | Flexible, based on budget | Consider recording needs separately | | Student Films | Portfolio building | May accept lower rates for credit/experience | ### Negotiation Approach ``` EN LA PRÁCTICA: Fee Negotiation 1. Ask about the total project budget first 2. Calculate a starting point (3% for music is standard) 3. Factor in any recording needs separately 4. Consider the relationship-building potential 5. Use a lawyer or agent for larger projects to maintain creative separation ``` > "I would first ask, what is your budget for the film? And if you can get 3% of the budget for music, you can make a judgment call. Let's say it's a half a million dollar budget, so that's $15,000." ``` FAQ: BUSINESS Q: How do you handle requests for orchestra when the budget doesn't support it? A: Get quotes from recording facilities, then either present these costs separately or suggest alternative approaches that fit the budget. Q: Is there a standardized rate card for composition work? A: Unlike other production roles, there is no composers union or standardized rate card. Fees vary widely based on budget, relationship, and experience. Q: How do you negotiate for future projects once you've established a rate? A: For increasing budgets, explain that previous rates were based on those specific budgets, and new projects with larger budgets should have proportionally increased fees. ``` --- ## Summary: Key Principles 1. **Monitoring**: Calibrate your system to 80 dB SPL for consistent mixing decisions 2. **Stemming**: Deliver 4-6 well-organized stems that provide mixing flexibility while maintaining your artistic intent 3. **Mixing Approach**: Start with featured elements or build from the bottom up; consider dialogue when making EQ decisions 4. **Levels**: Deliver with peaks between -6 and -3 dB for optimal balance between headroom and signal strength 5. **Workflow**: Develop efficient mixing practices that maintain quality while respecting tight deadlines 6. **Quality Control**: Always verify your stems are properly named, contain appropriate content, and sync correctly with picture 7. **Hardware**: Invest in adequate RAM and processing power to handle simultaneous DAWs and video playback Remember that technical excellence supports creative expression—the goal is to deliver your musical vision in a format that gives production teams the flexibility they need while preserving your artistic intent.
