Pink noise is a type of noise that we perceive as being balanced throughout the frequency spectrum. This means that, to our ears, the low frequencies sound as loud as the high frequencies. People have noticed that a well-mixed song has a similar shape to pink noise on a spectrum analyzer. I put a great mix through an analyzer to show you that.
1. Turn down the output of your audio interface so you don’t blow out your speakers, headphones or ears.
2. Add a tone/signal/noise generator plugin to a spare track in your DAW. In most DAWs, you’ll find this tool in your stock plugin library.
3. Set the plugin up to play pink noise at around -12dB.
4. Loop the section of your song where most of the tracks are playing (usually the chorus).
5. Solo the pink noise track. Keep it soloed throughout this process.
6. Solo the first track in your song.
7. Increase the fader level on this track until it can barely be heard over the pink noise.
Mixing with pink noise won’t help you make better-sounding music.
