Example launch line

Echo effect with controllable effect-ratio, delay-time and feedback.

gst-launch filesrc location="melo1.ogg" ! oggdemux ! vorbisdec ! audioconvert ! audiodelay drywet=50 delaytime=25 feedback=75 ! osssink
gst-launch osssrc ! audiodelay delaytime=25 feedback=75 ! osssink

In the latter example the echo is applied to the input signal of the soundcard (like a microphone).

GstAudioDelay

typedef struct {
  GstBaseTransform element;

  guint drywet;
  guint delaytime;
  guint feedback;
} GstAudioDelay;
