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]

Lotus1: How will the recording level affect the amount of noise? It doesn't. The noise is there. But i think the higher the input level is the less you can here the noise in the recordings. Regards, Karl ŤThe Crux of the Biscuit is the Apostropheť	[reply]

The OP was incomplete with more details dribbled out as the OPer deflected and discounted the offered possible solutions. My question was attempting to get the OPer to give more clues as to the experience level and goals. On my XP laptop under the audio properties the microphone input level can be set. The OP doesn't say why the level needs to be set in the Perl program or if it needs to be continiously changed. Maybe the OP wants to implement compression or some effect. I didn't want to invest too much effort in answering someone who didn't search google for the modules or to give better details up front but it is a topic I am highly interested in.	[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]

We're getting off topic here but I'm curious why you think the recording resolution will affect the recording level? A high resolution or high frequency sample of a small signal is still a small signal.	[reply]

Lotus1: ...but I'm curious why you think the recording resolution will affect the recording level. I didn't say this. But i'm shure that increasing sample rate/sample depth will decrease ~~signal-to-noise ratio~~ noise. The input level is another thing.
