Mixing Rap Vocals with Frequency Dependent Sidechain Compression

Transcript:

Hey Guys, Matthew Weiss, www.weiss-sound.com, www.theproaudiofiles.com. I’m going to show you a little alternative to traditional EQ and compression which is using a compressor with an EQ’able¬†sidechain. And using that to reduce the apparent content of a certain frequency. I’m going to play this vocal for you and then I’ll talk about it.

Overall the vocal sounds pretty good but from time to time it’s sounding a little bit too nasally. There’s a little bit of a tone around the 1k zone that just pops out. But it pops out in a dynamic way. It’s either not too present at all or it’s just flying forward. So, a good way to address this is to grab a compressor and if it has something with a sidechain, you can EQ the sidechain to focus in on a certain frequency band.

So instead of the compressor reacting to the entire sound, it’s actually just reacting to a given frequency. This is not the same as multi-band compression. Multiband compression would only reduce that frequency. This is going to reduce the entire signal, but it’s only going to reduce this entire signal as a reaction to that specific frequency. In other words, here’s the signal in itself.

Here’s what’s feeding the detector circuit of the compressor.

Here’s the result.

So it’s not really EQ, it’s compression, but it’s compression that’s reacting to such a specific frequency, it almost acts like EQ. I’m not so sure I actually set the band right though.

[rap vocals]

Yeah I think I might like that better. I’d have to play with it for a bit, but anyway, that is a way of using frequency-dependent compression.
