He wanted, basically, to de-ess the signal-only de-essers didn’t exist yet. Our goal is to introduce the concept of the sidechain, and build towards helping you understand sidechain compression in a holistic way.Ī cinema sound designer named Douglas Shearer wanted to make some spoken dialogue quieter whenever the actor said a sibilant word. So, compressors have been used, throughout the years, to alter music in colorful, impactful ways. This is one use for a compressor.Ĭompressors are audio tools, and audio engineers are naturally curious people who love to experiment.
If the difference is too much, you can use a compressor to restrain the loudest bits, so that their amplitude doesn’t rise as high as it would un-compressed.
The phrase ‘Dynamic range’ actually indicates the difference in dB between the noise of an audio system and the level at which it distorts. Now, what is dynamic range? Most people use the term dynamic range to refer to the difference between quiet and loud sections in audio and musical programs. A compressor is used to reduce a sound’s dynamic range-that is, to make the louder and quieter parts of the performance closer to each other in level, be it an instrument, a loop, or even a whole mix. Finally, adjust the parameters of your gate and the intensity and pitch of your signal generator to achieve your desired tone.įor this tutorial I set the signal generator to 50Hz and put it rather loud so you would be able to notice it very easily, however it is best to listen with headphones as laptop speakers do not produce low frequencies very well, at all.Let’s start with the compressor. Now on the Gate set the key to the bus you just named KEY and remember to enable it! Set the output of your duplicated kick track to bus1 and rename it as KEY.
On the aux input, add a signal generator and then a gate. First create an audio track with some kick on it and aux input track – I have used a kick sample from the workspace browser – and then duplicate the kick so you have 2 audio tracks and an aux input In this tutorial, I will be showing how to side chain a kick drum to a signal generator in Pro Tools 10: One of the most notable uses is by Trevor Horn where he side chained the kick drum to a sampled bass guitar note so that every time the kick was hit, it triggered a bass note to give the kick more power in the lower frequencies – Frankie Goes to Hollywood – Relax Side chain gating has many useful applications in mixing and can be relatively simple to create.
