Hi,
I am developing a calculator simulator which can do simple beeps. The
simulator figures
out the frequency and duration of the beep and informs a separate thread
about it. That
thread is then supposed to perform the actual playing of the beep.
So far I have tried to use Synthesizer and I can sometimes get some
fragments of beeps to
occur, but it is very erratic and often/soon I tend to get:
<interactive>: fd:19: hPutBuf: resource vanished (Broken pipe)
after which no beeps occurs. Probably my thread dies when this happens.
Too bad. I thought Sox would be an easy and portable way. But people already
reported problems on Windows. Now Mac. I use Linux, where I also encountered
a bug recently. Maybe a Sox bug? Have you tried 'sox' package and included
examples alone?
Please see haskell-art archive. We had a discussion about such issues a month
ago or so.
I also have
http://hackage.haskell.org/package/synthesizer-alsa
where I output sound via ALSA. Would that be an alternative?
