Resample changes the sampling rate of the entire sound. Unlike Playback Rate, this command re-calculates and interpolates all the data so that the pitch and playback time are not affected. Use this command to convert any sampling rate to the standard CD rate of 44100Hz or the standard telephony rate of 8000Hz.
Resampling is done using a high quality polyphase algorithm with a filter length of 192.
If you have a sound recorded at 44100Hz and do not need CD quality, you can save large amounts of disk space by resampling the sound to 22050Hz or 11025Hz. This reduces the size by 2 to 1 or 4 to 1.
