Pickup sfront 0.54 01/27/00 from
http://www.cs.berkeley.edu/~lazzaro/sa/
From the change log:
Version 0.54 -- 01/27/00
[1] The sample wavetable
generator can now read
base frequency and loop
start and end points from
the smpl chunk of Microsoft
WAV files (Thanks to Kees
van Prooijen). MP4 file encoding
and decoding correctly packs
and unpacks this data into
the binary MP4 encoding.
Bugs handling 8-bit AIFF
and WAV file data in MP4
encoding and decoding and
in sample wavetable generator
fixed.
[2] Concat wavetable generator
bugs fixed.
[3] Several SAOL and SASL file
parsing errors fixed (thanks
to Bertrand Petit and to the
members of the SAOL Projekt).
[4] Non-ANSI strdup() calls
removed from sfront and
generated code.
-------------------------------
A few notes on [1]
[a] the "class sample" in the
MP4 binary description doesn't
allow for coding fractional
loop start or end points in
samples, so that info in the
"smpl" chunk is discarded.
[b] the "smpl" chunk can code
multiple loop points, and
multiple "smpl" chunks can be
in a WAVE file. the sample
wavetable generator always
uses the first loop in the
first smpl chunk. it is
pretty good about handling
smpl chunks in most positions
in a file (before or after
the data chunk is fine).
[c] reading loop data from an
AIFF file isn't supported by
the sample wavetable generator
yet.
