Was premature with the above statement. While using option -lavfi afir=gtype=gn fixed the considerable volume drop when converting from DSD, there was still a volume drop which I could have lived with. But in critical listening, the converted 24/176.4 tracks had less body and considerably less bass.

Now the BAD news. CD 16/44.1 was better than ffmpeg on-the-fly conversion!

Same problem, whether convolution is enabled or not. Looks like I will have to convert all my DSD files after all.


If anyone wants to do your own testing, suggest using 2L's free test materials on

Download (further down page) Hoff Ensemble: Blågutten: original CD 16/44.1, Stereo DSD 64, Stereo 24/96, and other versions as required. Blågutten has good bass as the beginning and the difference should be obvious...
