usb audio interface
 
Hello,

I need to make some automated evaluations of audio input and output measures of several sound cards and mp3 players.

Are you aware of a good enough USB audio interface that I could use to do this?

Regards,
David

You will be further ahead looking at Firewire interfaces. I can recommend this one from personal experience:

EDIROL FA-66 24Bit/192kHz FireWire Audio Capture

Thanks for the answers.

However, these models have standard specifications:
input dynamic range: 100dB (typical, -60dB input, A-weighted)
signal-to-noise ratio: 100dB (typical, A-weighted)

In order to evaluate the specifications of other sounds cards and mp3 players,
I would need to have much higher measures than these standard ones.

Is there any other product that I could use?

Regards,
David

If your PC has the Intel High Definition Audio chipset as part of the main board, you can use the ARTA software for fairly high-res spectrum analysis and frequency response tests -- 24-bit and 96kHz as minimums. You can Google ARTA. It has a full-feature demo mode.

Dave, can you post basline RMAA measurements of this unit, with no DUT connected?

From my tests, it doesn't perform as well as say a E-MU 0404 USB.

For me, the best in USB

Is someone says "DUT test" or "DUT testing" or "what DUT are you testing" i will reach across the internet with my soldering iron.

Sorry i just have a test at work that literally says "Please do not touch the DUT testing please".

Ok some one else can vent about hot water heaters now.
