🎙️ Hip Hop Vocal & Sidechain Compressor Calculator

Compressors that aren't mathematically timed to your beat either choke punchy transients or pump unnaturally. Calculate tempo-synced Attack, Release, and Hold times for kick-to-808 sidechain ducking, lead rap vocal dynamics, and 2-bus mix glue.

Recommended Attack:

Target Gain Reduction:
-4 to -6 dB
💥 Kick/808 Sidechain Secret: Set Attack to 0.1–0.5 ms so the kick transient hits cleanly without clipping. Set Release to exact 1/16th note (107ms @ 140BPM) so the 808 sub blooms immediately after the kick dies!
