wv(wave-viewer)

wv(wave-viewer) is a small terminal program that displays raw waveform data. It reads unsigned byte or 16‑bit samples from a file or standard input and provides simple interactive controls to inspect the data.

Build

Use the bundled Makefile.

$ make
$ sudo make install  # optional

Usage

$ wv filename

Passing - instead of a file name makes the program read from standard input. When fed with an endless stream the application will keep allocating memory for buffered data until it is terminated.

Controls

• h, l – pan waveform left or right
• i, o – zoom in/out on the time axis
• I, O – zoom in/out on the amplitude axis
• p – pause rendering
• q – quit
