audiotestsrcaudiotestsrc — Creates audio test signals of given frequency and volume |
gst-launch audiotestsrc ! audioconvert ! alsasink
This pipeline produces a sine with default frequency (mid-C) and volume.
gst-launch audiotestsrc wave=2 freq=200 ! audioconvert ! tee name=t ! alsasink t. ! libvisual_lv_scope ! ffmpegcolorspace ! xvimagesink
In this example a saw wave is generated. The wave is shown using a scope visualizer from libvisual, allowing you to visually verify that the saw wave is correct.
