- Fader creep
Fader creep is a colloquial term used in
audio recording to describe a tendency forsound engineer s to raise thevolume of individual channels on anaudio mixer , rather than lowering others to achieve the desired change in themix .Results of creeping
As a result, the faders (
potentiometers that operate by sliding up or down) or volume controls (rotary potentiometers) on themixing board oraudio processor gradually "creep" toward the maximum volume setting, which reduces the ability to manipulate the relative volumes between channels. It can also result inclipping ordistortion of the master mix, which is when the overall volume of sound is too great for the equipment orrecording medium intended to hold it.Multi track problems with creep
Fader creep can be a particular problem in audio mixing sessions for
multi-track recording s, where individual sounds held on separate audio tracks, or delivered by outboardMIDI orcomputer audio equipment are combined into the finalstereo presentation of the recording. For example, an engineer might compensate for a particularly loud drum track by raising the volumes of the voice, the guitar, and the piano to the point where all of the individual signals are competing forheadroom . A better solution is to lower the volume of the drums, and adjust the other channels accordingly.Live concert creep
In audio mixing for
live concert s, fader creep can result when ear fatigue (the diminishing of the ability for the human ear to hear clearly after prolonged exposure to loud sounds) reduces the ability of the sound engineer to hear the individual components of the mix (i.e. separate instruments and voices on the stage) accurately.It is
human nature , when one cannot hear a sound clearly, to turn it up, rather than the things around it down, so this is the main reason why fader creep occurs.
