Description

Parse a .wav file into raw or compressed audio.

Wavparse supports both push and pull mode operations, making it possible to stream from a network source.

Example launch line

1	gst-launch filesrc location=sine.wav ! wavparse ! audioconvert ! alsasink

Read a wav file and output to the soundcard using the ALSA element. The wav file is assumed to contain raw uncompressed samples.

1	gst-launch gnomevfssrc location=http://www.example.org/sine.wav ! queue ! wavparse ! audioconvert ! alsasink

Stream data from a network url.
