5 Minute Audio Tutorial: Dialogue Compression
Main summary
Key takeaways
Main Ideas / Concepts
- Goal: Learn dialogue/voice compression (works for vocals like rap/hip-hop, and specifically spoken dialogue).
- Core concept: A compressor improves intelligibility and consistency by:
- Reducing loud peaks, and
- Raising perceived average level.
- Applicability:
- You can use any compressor software (Pro Tools, DaVinci, Premiere, Final Cut, Logic, Ableton, etc.) because the parameter logic is the same.
- An additional automatic “one-control” compressor option is presented for faster workflow, especially for dialogue/vocals.
Methodology / Step-by-Step Instructions (Stock Compressor Approach)
1) Start with Threshold (set relative to average level)
- Adjust Threshold so it sits toward the higher end of the average signal level.
- Use either:
- Pro Tools’ reduction meter, or
- Your ear to judge how much it’s “clamping.”
- Guidance:
- If it clamps too much, raise the threshold.
- If spikes still get through, lower the threshold.
- Example context:
- With the preamp around -17, threshold is described as about right.
2) Set Ratio (how strongly peaks are compressed)
- Higher ratio = more compression
- Reference point:
- Lower ratio (~1:1) effectively does nothing.
- Recommended range for voice/dialogue:
- 2:1 to 4:1 as a “medium” setting.
3) Set Attack Time (how quickly compression starts)
- Recommended for voice:
- 5–10 ms
4) Set Release Time (how quickly compression lets go)
- Recommended for voice:
- 100–150 ms
5) Use Makeup Gain (restore average loudness after peak reduction)
- Explanation:
- A compressor mainly reduces peaks above the threshold.
- This lowers overall level, so makeup gain restores the average loudness.
6) “Down and dirty” outcome
- The approach is framed as a practical starting point for dialogue compression using built-in compressor controls.
Alternative Tool (Automatic Compressor Approach)
Purpose
- A custom plugin called “autocomp” is introduced as:
- Automatic compression designed for vocals/dialogue
- Tested on drums, guitar, bass, and full mixes
- Not ideal for full mixes, but strong for solo elements that must stay forward (dialogue/vocals)
How it’s Controlled (simplified interface)
The plugin includes a few controls:
- Lift control
- Compression control (main/only essential knob)
- Trim
- Safety limiter
What’s automated:
- Threshold
- Makeup gain
- Attack
- Release
- (essentially “everything else”)
Claimed Benefits
- Consistent level whether the performer is close to the mic or backing off.
- Can respond to whispers by lifting quiet moments.
- Because it’s an RMS compressor, it should produce less “pumping” than typical compressors.
Special Features Described
- Lift control
- Lifts lower-level signals (e.g., whispers)
- If turned off, whisper-level reduction/bringing-up is less noticeable.
Practical Workflow Notes
- Limiter toggle: can turn it off.
- Trim control: adjusts output level, with examples like:
- Spotify-style mixes (“pop”) may need more level
- TV mixes may require level to come down
