Subject: Re: Sound formats
I and my students have encountered numerous problems using WAVs (of
course, _we're_ not professionals!) as opposed to AIFFs.
Not at all surprising. Why? See below.
Aren't some of the WAVs compressed?
Not the main issue.
We've seen WAVs that worked in Rev fine on one platform but not
another,
and vice-versa (no apparent pattern, but, then, given that the WAV
solution appeared to be 'no worky', we didn't look, either).
FWIW...
Here's the problem: WAV files are so common, especially in the PC
world, that many programmers have used them as a base to come up with
their own bastardized versions specific to their software. There are
very many of these. Different headers, layered versions which contain
bundled data used for multi-track recording, etc.
The result is that some playback venues simply won't recognize some WAV
files, because of those shaded differences from what you might call a
'standard' WAV file (not entirely sure there actually _is_ such a thing
anymore)..
Example: I needed a particular very broad string orchestra synth sound
for my Roland SPD-S synth pad (which loads WAV files as well as sampled
clips), to use in a Easter Contata concert (along with a plethora of
real instrumentation) looking for a very effective overall final result
that would work. I transferred a Melody Assistant file into GarageBand
so I could use the effects AU's to get exactly the sound I wanted,
which, of course, creates an AIFF file, then passed through Sound
Converter to make it into a WAV.
It took maybe 15 -20 tries to get the Roland to recognize the files.
Eventually, after rebuilding the files in different sequences, trying
several different renaming techniques, a few different types of WAV
files, etc., I eventually got it to work.
None of that converting stuff was much fun, I must say. I had to give
up one evening because I was just too frustrated to go on. The next
day, after a good night's rest, I was finally able to get it. Over 6
hours total time, for _one_ long note (well, actually two, a 'D' and a
'C', but they were the same type of sound, played at different times in
the intro).
The result in concert, as simply a part, together with the live
instruments, was absolutely awesome, worth all the effort. Sometimes
that's how it is with music, isn't it?
All the best,
Ken N.
