How to compress and EQ dialogue using Pro Tools
Main summary
Key takeaways
Overview
This Pro Tools tutorial presents a practical, workflow-based approach to EQ and compression for dialogue, with an emphasis on documentary-style mixes. The speaker emphasizes there’s no single “standard” method—you should adapt techniques to your own workflow and priorities.
1) Loudness standards & targets (context before processing)
The tutorial begins with platform loudness guidance measured in LUFS (Loudness Units Full Scale).
- ATSC / LKFS -24 is effectively identical to LUFS.
- For a UK-broadcast oriented example, the target follows an EBU R128 approach:
- Waves Loudness Meter preset: EBU R128 (integrated -23 LUFS target)
- Mentions tolerance roughly -23 ± 0.5 LU
- Explains:
- Long-term integrated loudness vs short-term averages
- Short-term is approximately ~3 seconds
2) Main workflow: process in stages with “A/B” comparisons
A repeated strategy is to work in stages and continuously validate results:
- Use A/B comparisons (bypass vs enabled)
- Use a spectrum analyzer to locate harshness/energy regions
- Use a loudness meter to confirm level after processing
- Use duplicate playlists / “get back to unprocessed audio” so processing via AudioSuite can be A/B tested cleanly
3) Example 1 (parkour documentary): fix clipping + mid harshness, then control with compression
Problem observed
Rooftop recording with portable gear and GoPros introduces several issues:
- Low-frequency pickup (GoPros contribute surprisingly much)
- Dialogue sounds thin with mid-band harshness
- Slight clipping/crunch during louder moments
Steps shown
-
AudioSuite RX7 De-Clip
- Uses RX7 clip to address clipping/distortion.
-
EQ decisions
- Checks the spectrum to decide whether a high-pass is needed.
- Finds little energy below ~100 Hz initially (later notes around ~125 Hz).
- Addresses harshness around ~1 kHz using:
- “Heavy boost to find the problem frequency, then cut it.”
- Applies a high-pass filter after EQ because boosting earlier unintentionally pulled up unwanted low end.
-
Loudness adjustment
- Uses clip gain to compensate for earlier changes and get closer to -23 LUFS.
-
Compression
- Works conceptually with Avid Pro Compressor, then applies subtle dialogue compression:
- Dialogue ratio guidance: typically ~2.5–3:1 (not a hard rule)
- Key control references:
- Threshold (when compression starts)
- Ratio
- Knee (soft vs hard; uses ~5 dB knee as a natural-smoothing guide)
- Attack/Release (dialogue often discussed around ~5 ms attack and ~150 ms release from preset context)
- Keeps compression light to avoid audible pumping.
- Adjusts threshold so primarily peaks get controlled.
- Works conceptually with Avid Pro Compressor, then applies subtle dialogue compression:
-
Mix context
- Mentions dialogue compression supports intelligibility when background music is present.
4) Example 2 (convenience store recording): heavier dynamics + over-zero peaks, then EQ/noise reduction/limiting/compression
Observed issues
- Over-level / clipping peaks near or above 0 dB
- Dialogue recorded with store background noise
- Requires stronger control of extremes
Steps shown
-
EQ first (high-pass)
- Applies a high-pass starting very low (20 Hz) and increases until the audio sounds thin.
- Rationale: remove rumble early so it doesn’t unnecessarily drive later processors (especially compression/limiting).
-
Noise reduction
- Uses RX7 Voice Denoise in Adaptive mode
- Warns not to overdo it due to possible artifacts (“strange stuff”)
- Keeps NR moderate (example references roughly ~8 dB as a practical limit before artifacts become noticeable)
-
Clipping management via limiting
- Uses Waves L1 (limiter) before noise reduction
- Adjusts:
- limiter threshold/output so only problematic sections are reduced
- gain reduction using the meters
-
Compression after limiting
- Adds Avid Pro Compressor with a more aggressive approach:
- ratio starting around ~5:1, then adjusted
- knee/attack/release tuned to avoid pumping/artifacts
- Explains how compression reduces:
- loudness/dynamic range (example: ~8–9 LU down to ~4–5 LU)
- Raises output afterward to restore loudness target (makeup gain equivalent).
- Adds Avid Pro Compressor with a more aggressive approach:
-
Loudness re-targeting
- After compression lowers loudness, he raises output to return to approximately -23 LUFS.
5) Example 3 (mixed dialogue consistency + multiband stage)
This example focuses on making multiple dialogue recordings consistent.
- Routes multiple dialogue pieces to a dialogue bus (aux track)
- Performs:
- basic EQ/high-pass cleanup per clip
- then multiband compression to smooth differences between speakers/recordings
- Mentions multiband processing using:
- MADSP SA2 Dialogue Processor
- Notes the multiband thresholds are tuned across bands so frequency-heavy/louder content is controlled more specifically where it matters.
- Encourages evaluating both:
- by ear
- and by reference
- Goal: reduce differences between wildly varying sources (different locations, microphones, environments).
6) Tooling alternatives: Clip Effects vs AudioSuite (plus EQ match mention)
Clip Effects (Pro Tools Ultimate)
- Real-time, clip-by-clip processing (no need to render like AudioSuite)
- Can’t show gain reduction visually like some plugins
- Suggests using an extreme threshold test to confirm audibility
- Can render clip effects if desired:
- renders updated waveform and “bakes in” processing
EQ Match plugins (mentioned as an alternative)
- Mentions EQ Match ideas (e.g., isotope EQ match)
- Cautions that matching voices/recordings doesn’t always work (because source differences may be too complex or undesirable to match automatically)
7) Key best-practice guidance emphasized
- Rely on multiple A/B comparisons and reference dialogue
- Don’t chase changes that only “look correct” on meters:
- Listen with and without processing and judge by results
- Compression may be hard to notice until it’s heavy:
- start light, then adjust once you understand the effect
- Keep TV dialogue dynamics restrained:
- many TV viewers use poor speakers, so overly dynamic dialogue can get lost
- Limit processing complexity:
- uses a personal maximum around ~5 plugins per track (beyond that, results may not improve)
