Subject: [PATCH alsa-lib 0/2] Allow multiple formats for PCM rate plugin
Date: Thu, 17 Jun 2021 12:01:25 +0200	[thread overview]
Message-ID: <20210617100127.12068-1-tiwai@suse.de> (raw)

Hi,

this is a patch set for alsa-lib to extend the PCM rate plugin for
allowing multiple formats for its converter plugins.  This optimizes
and improves the quality (skips the unnecessary buffer and conversion)
when the converter supports the source and/or the target format
natively.

The patches for libswresample and libsamplerate will follow.
