From f2524f71d7b7fd2e03e4b7927833798d65492746 Mon Sep 17 00:00:00 2001 From: Sebastian Dröge Date: Sat, 24 Jan 2009 11:53:40 +0100 Subject: Add note that audioecho's reverb sounds metallic Add a note to the docs that audioecho's reverb will sound metallic. 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. --- gst/audiofx/audioecho.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'gst/audiofx') diff --git a/gst/audiofx/audioecho.c b/gst/audiofx/audioecho.c index 04d51240..451506d6 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.
