I already written about side-chain compression, so here’s a tip how to use it in a more subtle – yet effective – way: separate the bass in low, mid and high frequencies and then have the kick drum trigger the compression only on the low end of the bass.

  1. Make three copies of the bass (or create parallel channels).
  2. Isolate the bass in three frequency ranges; low 20-160 Hz, mid 105-950 Hz and high 550 Hz-7 kHz. It’s okay overlap some.
  3. It’s possible to pan the high and the mid slightly wider, but keep the low end in mono.
  4. Now side-chain only the channel with the low frequencies by -6 dB or so.

By doing this, the low end of the kick will be audible whilst the overtones of the bass will be kept intact.
