de.sciss.eisenkraut.io.AudioTrail
This class provides means for automatic multirate handling of nondestructive nonlinear track editing objects. It wraps a number (currently 7) of track editors representing the same signal at different decimation stages where one file represents fullrate data and each subsampled file decimates the rate by 4. Thus, if fullrate corresponds to 1024 Hz sampling rate, the first subsampled file is a decimation to 256 Hz, the second subsampled file is a decimation to 64 Hz etc. So, using 6 subsampled files goes down to 1/4096th of the fullrate. Taking the unusual case that a user would use audio rate for sense data, say 48 kHz, then the lowest resolution subsample file will run at about 12 Hz, so if a GUI element request data for a very long time span, say half an hour, it would have to handle a buffer of 21094 frames; in the more usual case of a sense rate of say 4800 Hz (or less), one hour could still be represented by 4219 frames, thus maintaining low RAM and CPU consumption. @author Hanns Holger Rutz @version 0.70, 12-Nov-07
