Describe
DSD playback is staticky unless DSD_DECIMATE is redefined to 0 in ChunkList.h. If DSD_DECIMATE is defined to 0, output level drops to "SACD 0dB" (aka -6dB) as expected, but output quality is good.

To Reproduce (delete if not applicable)
Steps to reproduce the behavior:

  1. Obtain a DSD file. The files I'm using are DSD64. You can obtain a DSD64 sample from NativeDSD at no cost.
  2. Play the file.

Expected behavior

Playback should be free of static or other artifacts.

Version information:*

  • macOS version: 13.4
  • Cog version: Version 2777 (2777-g728ae813c)

Confirmed, this is fixed now. I suppose audio is still at -6dB compared to PCM; I've opened #368 as a feature request related to this.

It's really not -6 dB compared to PCM. The filter the decimator uses has a +6 dB gain anyway, which is why I correct it on output.
