4.2 Wave form handling

There are some utility functions to help handling wave forms:

wave-concat waves

Append wave forms and return the resulting wave form. waves must be a list of wave forms to append.

wave-subwave wave from-time to-time

Return the part of wave form that starts at from-time and finishes at to-time. Both times are in seconds.

wave-load filename

Load and return a wave form from filename. This function is similar to wave.load, but more sound file formats (most significantly Ogg Vorbis, if your SoX installation supports it) can be loaded.

wave-utt wave

Create and return an utterance, that contains just the Wave relation holding wave.

wave-import-utt filename

Create and return an utterance, that contains just the Wave relation holding a wave loaded from filename via the function wave-load.
