PCM peak-level filter

A quick C program -- read 16-bit stereo PCM from STDIN, output peak levels. JSON output available.

  • This is not checking for endian-ness -- assumes little-endian data (WAV standard), and that you're on a little-endian machine (Intel or ARM, for instance).
  • This program will exit when STDIN closes.
  • An example application, using websocketd my own LED-Audio-Meter is available.
