Hi all,

Long story short, I am looking for some help on making recordings using the voice modem.

I've purchase a voice modem, but the quality of the recording doesn't live up to my expectation (maybe because it is only $40 CAD?). The recordings has too much noise, and the number of bits per sample is only 8 bits (I thought I can get 16).

Anyways, could anyone please offer some tips on making good quality recordings using voice modems?

Thanks in advance.

Wei

The bandwidth of a voice (POTS) phone line is around 3kHZ. Not conducive to any kind of quality recording - far worse than any AM radio station.

That's wright, i have the same problem with
Creatix V90/56k external modem.
Creatix Lifetec GC 326.0 modem
http://www.creatix.com/support/frames.html
V.90 (external)
it records PCM 8.000 kHz, 8 Bit, Mono
and i discovered that vor voice a minimum of 22khz is the minimum and 16 bit for dynamics of course.

Maybe you know there are external adapters that link tel line to the sound card input, so you can set at your choice.

You damn sadist, you try to make people think!
