record sound problem on windows

[Slava Paperno]

Alex,

Your Windows test wave file sounds like some recordings I've seen where the
sample rate or sample size is not stated correctly in the file's header.
I've seen this happen with some audio drivers that are not capable of
recording at a particular combination of sample rate and depth.

I downloaded your test stack from the bug database and tested it in Windows
7 and Windows XP. I had to build a standalone because I don't have LC IDE on
the XP machine.

In Windows 7, I saw no problems recording and playing back from either IDE
or the standalone. In Windows XP your standalone recorded one click per wave
file (a tiny wave file at that), nothing else. I then modified your stack to
include a call to QTVersion in openCard (to make sure QT is loaded), and
also to set the sound parameters to 44 kHz, 16 bit, 2 channels. This still
worked fine in Windows 7, and produced a good recording in Windows XP,
except that for some reason the wave file could not be played by the Sound
Recorder, although it played fine with the VLC player. This may have to do
with the codec that QT used to make that compression. I didn't look into
that.

I think you can try loading QT in openCard and using different recording
parameters. I am no expert in LC or its sound capabilities, but I will need
to record sound in my next project, so I'm trying to learn about it.
Compared to Adobe Director, which I had used for ten years before I started
playing with LC 8 weeks ago, the sound recording and playback functions in
LC rudimentary. Which makes me think that some real programmer may have
written an external for sound in LC that you and I don't know about...
anyone knows more this?
