Redmine Audacious - Bug #854 (Closed): Floating-point WavPack files play as noisehttp://redmine.audacious-media-player.org/issues/8542018-12-22T19:38:36ZAlexander Kabikov
<p>I'm using a USB DAC that supports up to 24bit 96kHz playback. I also have a number of 32bit(floating point) / 192 kHz files. I've set alsa output to hw:card=v15, direct hardware without any conversions, mixer to hw:1 (same usb device) and mixer element to pcm. I've enabled Sample Rate Converter to convert 176.4kHz to 88.2kHz and 192kHz to 96kHz with Best sinc interpolation. The device I'm using can't use 16bit input natively, it always requires 24bit. In Audio - Bit Depth is set to 24bit to be able to play 16bit files too (that is done correctly as far as I can tell, sounds good). However, when playing the 32bit files with these settings, it is unable to play them correctly and is instead sending out noise. You can hear some notes in the background, but it's clipping very hard. Soft-clipping option didn't help either btw.<br />My guess is that a process similar to down-sampling is required in this case, changing only the bit-depth to 24 bit, and not just cutting it.<br />Also, hearing that noise I figured that the playback speed is correct, so resampling is doing it's job.<br /><code>not sure if category/affected version are set correctly, I've built from git on 21.12.2018</code></p>
