Topic: USB 24/96 testing and Minime

[it-goes-to-eleven]

I ran 9 hours of 24/96 testing on my laptop last night (under Linux) with USB and a UA-5.  There were no USB transport errors reported and that is encouraging.  The source was analog, so I am unable to do any extensive correctness testing in this case.

Ultimately, I want to do this with the Minime, not the UA-5.  And because the Minime lacks digi-in, it does not seem possible to do digital comparison based correctness testing.

I have considered writing a software tool to scan the samples and look for excessive sample to sample amplitude changes that would suggest noise. While that wouldn't catch everything I think it would cover some important cases.  A tool that could do a 'fuzzy' compare of the original digital source and the final digi->analog->digi result would be ideal.

Any suggestions on how to validate the Minime at 24/96 with USB for Many hours (ideally automated)?

Unfortunately the MiniMe won't do 96 KHZ via USB.

EDIT:

From apogee's site:
Plug and Play with USB
The Mini•Me’s low-latency USB interface carries two channels of audio at up to 24-bits and 48 kHz sampling*, from the Mini•Me to the computer and back again for monitoring.

I'm one of the few to report many many successful 24/96 ua-5 usb recordings.
