What is sidechain compression?
- tetraodonpuffer 10y agoyou put a compressor on the background music with the sidechain input set to the channel your microphone is on, so when you speak the music is automatically pushed to the background and you can actually hear the mic.
- elbigbad 10y agoIn this case, it's basically where when the presenter is speaking, the music quiets at the exact moment, so you can hear more clearly but still have the music.
- nogenerix 10y agoRather than having voice over and background music clashing at the same volume levels, the music level would decrease whenever the voice over signal is active.
- tantalor 10y agoThanks! Confusing because I think "bitrate" when I hear "compression" but it actually refers to the volume level.

An automated way to do this is in audio production is by using the sidechain input of a dynamic range compressor. https://en.wikipedia.org/wiki/Dynamic_range_compression#Side-chaining https://en.wikipedia.org/wiki/Dynamic_range_compression#Side...
