For your research purposes ensure that you can identify and explain:
- A brief overview of the history of compression (from 1930s-today)
- Key innovations
- Typical parameters – threshold, ratio, make-up gain, attack, release, output, knee
- Typical applications
- Side-chaining, parallel compression, limiting, multiband compression.
Here’s a really snappy, visual explanation of compressors which will consolidate your understanding further. Thanks to wickiemedia wherever you are. Nice!
THIS document will give you the lowdown on the history and key parameters of the compressor.
