Sound is composed of a series of sines waves, all coming together to give you a sense of purpose to the audio wave. For practical purposes, each sine-wave is called a partial.
When you normally mix two tracks, the partials/sine waves from both tracks tend to combine in unpredicatable ways. When they were in phase they will amplify each other. When they were of opposite phase they would cancel out. When their frequencies slithly differ, a low frequency oscilation would be introduced. Generally, none of these 'features' are really desirable.
With BpmDj's new 'partials mixing' mode, none of these artefacts take place and all partials will be analyzed and resynthesized to generate the smoothest sound possible. Werner his page demonstrates the difference between the two types of fading.
turns on or off the partials mixing.
Because the volumes are predictable it is also no longer necessary to try to compensate for the 'total volume' that could potentially be present; which is either achieved by fading out the old song and fading in the new song (the sum of the two volumes is always 1); or by using a limiter after the mix stage. Instead, when partials are on, just leave the old volume as it is, until you brought in the new track, then fade out the old. In other words you want to combine a partials fading with the following volume fades: .
