agingradio

An element that adds age to an audio stream using various kinds of distortion. Imagine listening to music on a very old and broken radio, or waiting on hold at a customer service hotline where the hold music sounds horrible.

Currently supports: White noise of configurable amplitude, clicks of configurable probability, lowpass filter of configurable frequency, quantisation noise of a configurable amount of bits, and cubic curve distortion of a configurable amount and number of passes.

Example pipeline

 gst-launch-1.0 filesrc location=music_file ! decodebin ! audioconvert ! agingradio !
 audioconvert ! autoaudiosink

This will play back the music file using the default distortion parameters.
