Study Notes

Compression in Music Production

Compression is a tool that controls the dynamic range of audio.
It reduces the difference in volume between loud and soft parts of a sound.
This can involve making loud parts quieter (downward compression) or soft parts louder (upward compression).
Compression can alter a sound's character and create cohesion within a mix.
It can be applied to individual elements (like a kick drum), groups of sounds, or the entire track.

Key Compressor Parameters

Threshold:
- The volume level above which compression is applied (expressed in dB).
- A lower threshold compresses more of the sound.
- Be cautious when adjusting volume after compression. Input volume changes affect compression level.
Ratio:
- Determines how much compression is applied.
- Higher ratios (e.g., 8:1) decrease the difference between loud and soft parts more drastically.
- Lower ratios (e.g., 1.2:1) apply less extreme compression.
Gain Reduction:
- A measurement of how much compression is applied.
- Calculated as the difference between the input signal's level and the output signal's level.
Attack:
- The time it takes for the compressor to start reacting to a sound exceeding the threshold.
- Fast attack removes sudden peaks.
- Slow attack allows transients to remain unchanged.
Release:
- The time it takes for the compressor to stop reacting to a sound that's no longer above the threshold.
- Fast release can create a pumping effect; slow release sounds smoother. Faster releases leave less chance of affecting transients
- Long releases may affect transients.

Using Compression Effectively

Compression serves both as a tool for control and as an effect.
Moderate use is generally preferable to heavy compression, which can flatten the sound.
Avoid over-compression, which can diminish transients and highs, creating a dull sound.
Understanding compressor parameters is key to desired results.
