    I could only test the algorithm with my hardware and until now nobody else posted results of some tests. So there is not much empirical data. I assumed that the results are much better than with results of your test...

    That does really not look good. Can you have a look at the signal on the Teensy without resampling? I only had a brief look at you code, but I think replacing the AsyncAudioInputSPDIF3 object with an AudioInputSPDIF3...

    Hi, you don't need to change the sample freuqency of the library. From 48kHz to 44.1kHz is no problem. The the resampling algorithm, that I implemented, is quite simple. It is described here:...

    @Bill Glass: I was also pleasantly surprised about the low distortion and I am curious about your results. Two things that you need to take into account: When the resampler is initialized, it uses the input frequency...

    That's difficult to answer. Some months back, I did some tests in which I want to get a feeling about the amount of jitter of the Teensy spdif-output. I can share the results although they don't exactly answer your...

    Hi, I don't know/own an audio board, but I can tell you how I interface the Teensy with an optical cable. I use this optical receiver: https://www.cliffuk.co.uk/products/optical/FCR684205R.pdf On the last page there...
