Given that AIFF files are PCM encoded, the default value of the slot @pcm is TRUE and remains untouched. The slots @bits, @samp.rate are read from the source object. Note, however, that should the source bit-depth be a value unsupported by wave files, the function will exit with an error message.
For class "Wave" , the slot @stereo is set to FALSE if the input is a vector or single column, and to TRUE if there are two columns.
