Importing DPCM samples

This feature is used to convert Microsoft wave files (.wav) to 1-bit DPCM samples, as used by the NES hardware's sample channel. The format of the wave files must be PCM, no compressed formats are supported. Sample rate, sample size and channel count doesn't matter, the file will be resampled according to the quality setting.

Choose import in the DPCM instrument editor dialog, select a file and you will be asked to select a quality and volume setting:

Maximum supported size of one DPCM sample is 4 kB, at quality 15 (33 kHz) it's a little less than one second and lowest quality (4 kHz) about eight seconds.
