 This folder includes a python script which runs the C emulators for the ASRC, SSRC, OS3 and DS3 modules.
-For each model we present test signals - both a single tone to test the THD performance and a range of tones to
-observe roll-off at the top of the band.
-Using an un-windowed FFT we calculate the SNR.
-We scrape the logs to extract MIPS/Utilization where supported.

 Tests are run for all suported input and output sample freqencies, and for worst case frequency deviation.
-Note that not all modules support all input scenarios - these are ignored.
