From 15c0cee6c809a137e0fc7f1d2b0867cc03473c0c Mon Sep 17 00:00:00 2001 From: Ben Collins Date: Fri, 28 May 2010 11:43:45 -0400 Subject: ALSA: pcm: Define G723 3-bit and 5-bit formats This defines the 24bps and 40bps (8khz sample rate) G.723 codec formats. They are going to be used once I submit the driver for an mpeg4/g723 compression card. I've updated the signed value to -1 as per Takashi's comments since these are non-linear formats.
