RE: Confirming bit-depth & sample rate in Windows ?

Posted by PAR on July 1, 2017 at 14:44:25:
How have you configured your replay ? if it is WASAPI then the data passed to the DAC should be as per the original file. If you are using e.g. Direct Sound which uses the Windows 10 mixer then the data rate passed to the DAC will be as set by you in Sound/playback/properties/advanced. Many think that the sound specification set here e.g. 24/192 specifies the maximum file bit depth/ sample rate processed. In fact is it is the rate that everything will be upsampled to. Similarly if you select a rate lower than the original file it will be downsampled to that.

So, use WASAPI or kernel streaming and the file delivered will be as per the original. NB: Win 10 does not support ASIO.

I hope that this helped although it is not exactly what you asked.
