A faster release means the compressor lets go quickly, and the signal retains more of the original dynamic. Middle - With a very fast release time, the gain reduction is removed very quickly, and this rapid change of dynamics is perceived as adding loudness. I hear this all the time " You should try to match release time of your compressor to the tempo of the song" but no one actually explains HOW to do this. Too short of a release time will result in audible pumping; too long and the compressor will rarely if ever return to its zero state, resulting in nearly constant gain reduction. Can someone kindly help? The sweet spot occurs when the release time complements the attack time. 23rd June 2009 #17. Maybe I am answering my own questions. Share Reply Quote. Pumping is when the compressor clamps down on a note, but releases too quickly – so that the end of the note is actually louder than the middle of the note. To compensate for this, we can use the makeup gain parameter and … See this in the guitar tracks below: Uncompressed vs. compressed. In that way, the percussive decay is retained au naturel, but the compressor still recovers quickly enough to be ready for the next loud percussion strike. fast, medium, slow? The release time is a little trickier since the goal is to get the action of the compressor to blend in with the musicality of the track. Mistake #5: Using a Fast Release Time. The longer the release time, the longer the compressor holds on to the signal, and the smoother the sound. If the release time is too fast, a phenomenon called “pumping” can occur. J CraQ. Because compression will only impact the sound while it’s crossed the threshold, the loudest parts of the resulting signal become quieter. And other way around, how can I benefit from doing this ? However, where there is a relatively obvious noise floor the rapid change in ambient noise level will be obvious and may be distracting. Lives for gear . This is called 'noise pumping'. So let’s listen to what that sounds like on a solo instrument. I'm just trying to keep up with the jargon so when I read other folks posts I can relate. What is the fastest release time a compressor can offer? Or do "Fast" "Medium" "Slow" all relate to the source at hand? Using a fast release time can be just as bad. I would be very grateful I'm really not sure how to set my release control on compressor to follow the tempo of the song. Release Time of Compressor plugins for Vocals. While slow release gives gentler overall dynamic shaping but can suck the soul out of the dynamics because depending on the setting, it might not reset fast enough to allow the transients through on a slow attack setting. Can you wise guys share this secret with me ? different compressors? The release time determines how long it takes for the compressor to go from full compression to zero compression. Fast Release Time – If you set up the release time very fast then you feel that the breathing and tail ends of vocal become more prominent and aggressive because fast release time increases the dynamics of low volume areas. In those rare situations, it can be beneficial to retain a fast release time, but hold off the start of the release for a while after the input signal has decayed naturally. Fast release will reset the compressor quickly which is useful for sounds that have quick movement but can have the potential of unwanted pumping.
