I'm seeking for a Mathworks tool or interface that supports audio codec performance.
SNR, Total harmonic distortion, cross-talk, ISI, and other DAC and ADC performance characteristics for audio codecs
Any assistance would be greatly appreciated.
Thanks

Hi, I think the Spectrum Analyzer could help. Here is an example:

Are you using Windows? If so then it is possible to get a loopback driver that can copy output to input without going through hardware. You would use that to test what the actual digital signal is. When you create a hardware loopback as a patch between output and input you are also implicitly testing the quality of the output hardware, and the cable, and the input hardware.
