Subject: alsa-lib resamping error
Date: Wed, 22 Jan 2003 12:38:31 -0500 [thread overview]
Message-ID: <200301221738.h0MHcVq22269@linuxaudiosystems.com> (raw)
if you try to play a 22.05kHz stream on hardware that supports 32kHz
and 44.1kHz but not 22.05kHz, alsa-lib's plughw layer chooses to use
32kHz and resamples. this seems like an error to me: it would be much
better to choose 44.1kHz and do simple integer resampling. that is:
the search for the best rate should first try integer multiples and
divisors of the desired rate, not the "closest" rate.
