WaveSurfer

WaveSurfer is an audio editor widely used for studies of acoustic phonetics. It is a simple but fairly powerful program for interactive display of sound pressure waveforms, spectral sections, spectrograms, pitch tracks and transcriptions. It can read and write a number of transcription file formats used in industrial speech research including TIMIT.

Features

Wavesurfer provides basic audio editing operations, such as excision, copying, pasting, zero-crossing adjustment, and effects such as fading, normalization, echo, inversion, reversal, replacement with silence, and DC-removal, but, in view of its scientific orientation, does not offer effects of interest to musicians such as flange.

Development

Wavesurfer is written in Tcl/Tk using the Snack audio library. It therefore runs on most platforms, including Microsoft Windows, Mac OS X, Linux, Solaris, HP-UX, FreeBSD, and IRIX. It is scriptable and supports plugins.
