From 1f7decc1a0a7e0f2fb547ee740ee0d7b659c0406 Mon Sep 17 00:00:00 2001 From: Martin Date: Tue, 12 Feb 2013 09:53:33 +0100 Subject: Rename af_volnorm to af_drc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The previous name of this filter was misleading, because it doesn’t actually normalize volume levels. What it does is closer to performing low-quality dynamic range compression, hence it is now called af_drc. --- DOCS/man/en/af.rst | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'DOCS/man/en/af.rst') diff --git a/DOCS/man/en/af.rst b/DOCS/man/en/af.rst index aff84114d0..a47a63b8e2 100644 --- a/DOCS/man/en/af.rst +++ b/DOCS/man/en/af.rst @@ -428,8 +428,9 @@ extrastereo[=mul] (average of both channels), with 1.0 sound will be unchanged, with -1.0 left and right channels will be swapped. -volnorm[=method:target] - Maximizes the volume without distorting the sound. +drc[=method:target] + Applies dynamic range compression.
