Properties


  "delaytime"                guint                 : Read / Write
  "drywet"                   guint                 : Read / Write
  "feedback"                 guint                 : Read / Write

Description

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

Example launch line

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).
