    Allo Revolution DAC

    Merging Technologies founder talk - digital filtering and other things about listening

    Interesting talk from Merging Technologies founder. Especially the DSP part. I'm not an expert but am I correct that he has a personal preference for slow roll-off linear phase filters, over fast roll-off? For better time domain performance? Or have I not understood clearly? Please correct me.

    Measurement of a DA and AD using loopback - what software to use and test signals

    Hi all I'm considering to demo a DA and AD. I can't send to Amir so I would like to do my own simple measurements. It won't be as revealing as Amir's setup but hopefully should show if something is broken. Is there a simple guide on software to use on macOS and where to find test files?
