This is version 1.1 of AIFFWAVE, a utility that converts an AIFF file (Audio
Interchange File Format, typically used on Macs) to a WAVE file (used on
clones). It should be run from an OS/2 command prompt window.
This version corrects a bug in version 1.0 that resulted in possibly a
little distortion of the end of a wave. Furthermore, this version adds 2 new
switches, -r and -s.
The -r switch forces the sample rate to be one of the 3 "MPC standard
rates" of 11025, 22050, or 44100 KHz. AIFFWAVE will round the rate off to
the nearest of those 3. Note that AIFFWAVE doesn't do sample interpolation.
It simply changes the specified rate. The net result may be a shift in the
playback pitch of the wave. Use this switch if you're using software that can
handle ONLY those 3 MPC rates.
The -s switch converts all sample data from non-signed form (ie, where
the lowest value is 0 and the highest is 255 for 8-bit data) to signed form
(ie, where the lowest value is -128 and the highest value is 127 for that
8-bit data). Some programs write AIFF files with data in non-signed form.
This needs to be converted to signed form when converting to a WAVE file.
Unfortunately, there's no way to determine which form was used by examing the
AIFF file. You'll have to make the determination whether you need to use this
switch. If a resulting WAVE conversion file sounds distorted without using
the -s switch, then try using the -s and compare the sound of another
conversion. One of the two versions will definitely sound more distorted than
the other.
AIFFWAVE automatically strips any Mac binary header off of an AIFF.
The syntax for AIFFWAVE is:
AIFFWAVE [-r] [-s] aiffname wavename
where -r and -s are those optional switches, aiffname is the full name of the
AIFF file that you wish to convert, and wavename is the full name of the WAVE
file that you wish to make from that AIFF. Don't specify the same filename
for both.
AIFFWAVE is copyright 1994 by Jeff Glatt, but is freely distributable.
