Multiband Compressor
A multiband compressor is an advanced type of compressor that splits the audio signal into multiple frequency bands, each with its own compression settings. This allows more precise dynamic control.
Why Use Multiband Compression?
Different frequency ranges behave differently. A multiband compressor can:
- Tame harsh highs without affecting the low end
- Control boomy bass without squashing vocals
- De-ess or enhance specific tonal areas
Common Bands
A typical setup might include:
- Low (20–120 Hz)
- Low-Mid (120–1000 Hz)
- High-Mid (1k–4k Hz)
- High (4k–20k Hz)
Independent Controls Per Band
Each band usually has:
- Threshold
- Ratio
- Attack / Release
- Gain (for post-compression adjustment)
- Solo / Bypass / Mute options
Applications
- Mastering: fine-tuning the dynamics across the spectrum
- Broadcast: ensuring consistency across diverse content
- Live sound: isolating problem frequencies without over-compressing
- Vocals and instruments with wide tonal range
Example Use Case
You may compress only the high band to reduce hiss (e.g., tape or shellac noise), leaving bass and mids untouched — a typical setting in hiss reduction presets.
