For web audio, I reckon an occasional misjudged channel layout is
better than more frequent exceptions.
Signed PCM is normalized with unsigned max divided by 2, not
signed max. If you divide by the signed max (32767), you get headroom
that can exceed the threshold below -1.0. It's not audible, this mostly
matters for tests that assume correct normalization. But it turns out
there's no shortage of "golden ears" jackholes out there who swear they
can hear the difference.
We had numerous NiH-based implementations of audio formats and metadata
that we now no longer need because we either don't make use of the code,
or we replaced its implementation by FFmpeg.
This loader supports whatever format libavformat and libavcodec can
handle. Currently only seekable streams are supported, and we still have
some limitations as to the number of channels and sample format.
