This happens because for a real reverb filter additional filtering is necessary. Also note which values should be used for the delay property to get an echo effect. --- diff --git a/gst/audiofx/audioecho.c b/gst/audiofx/audioecho.c index 04d5124..451506d 100644 --- a/gst/audiofx/audioecho.c +++ b/gst/audiofx/audioecho.c @@ -22,9 +22,14 @@ * SECTION:element-audioecho * * - * audioecho adds an echo or reverb effect to an audio stream.
