Hi,

After reading about the need to test S/N ratios on audio equipment, I
thought I'd ask the NG for some recommendations on good audio test
software? What do people use? Any good freeware or do I need to spend
some money? Personal preferences?

Thanks,

Adam

Here's the free download:

This software will do a quick automated analysis of any piece of audio gear.
The tests are quite extensive including both SNR and dynamic rnage.

It was designed to test sound cards by looping the output of the sound card
to its input. You should do that first, in order to learn how the software
works and find
out how good your soundcard is.

However, any piece of gear you hook between the output and input of your
sound card can be tested with this software. The software presumes that it
has unity gain (input voltage = output voltage), but if the gear has more
gain, use a simple attenuator. A simple attenuator that often works well at
either the input or output of a piece of gear is a 5K 2watt AB type
potentiometer, like this one:
