I did a google search for 'perl win32 record audio' and the first hit was to Win32::SoundRec which looks like it is what you want.	[reply]

This is pretty much what I was looking for, thanks for the tip. It has very high level api calls but unfortunately, the MCI library seems limited as for how much I can configure the soundcard I'm recording from (audio is recorded too low with too much noise), so I guess I have to keep looking for a more robust customizable audio library API. I found that audacity uses the portaudio api, but the perl module to access that is too low level for me at this point.	[reply]

How will the recording level affect the amount of noise? I was going to test this module but found it won't install due to missing dependancies on CPAN.	[reply]

ress, i didn't use Win32::SoundRec yet. But from the manual: `record([$bitspersample, $samplespersec, $channels])` [download] ...The three parameters are optional. $bitspersample defaults to 8, $samplespersec defaults to 11025, $channels defaults to 1. Even cheaper cards have up to 24Bit/96kHz. Did you try? And perhaps using a preamp/mixer? Regards, Karl ŤThe Crux of the Biscuit is the Apostropheť	[reply] [d/l]

redss: One compatible with your computer, operating system, microphone input device and version of perl. Try looking on http://cpan.org for one. ...roboticus When your only tool is a hammer, all problems look like your thumb.	[reply]

Sorry, I forgot to mention that this is for Windows. I had already looked on CPAN but couldn't find a library. I'm sure what I need is there but would like a recommendation I'd like to be able to initiate and terminate the recording of an audio file from within perl. thanks!	[reply]

redss: I see what you mean. I just looked, and while I found Win32::Sound, it was only for playing sounds. You may have to use Win32::API and connect directly to the Windows sound API to do your recording. ...roboticus When your only tool is a hammer, all problems look like your thumb.	[reply]
