5 Minute Audio Tutorial: Dialogue Compression

Main summary

Key takeaways

Educational

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
