Functions are provided to read and convert AIFF audio files to WAVE (WAV) format. This supports, for example, use of the 'tuneR' package, which does not currently handle AIFF files. The AIFF file format is defined in < https://web.archive.org/web/20080125221040/http://www.borg.com/~jglatt/tech/aiff.htm> and < https://www.mmsp.ece.mcgill.ca/Documents/AudioFormats/AIFF/Docs/AIFF-1.3.pdf> .
