equivalent PCM rates for converting DSD files?

[Daverz]

Dear all,

I have some big, space-wasting DSD files which I want to convert to PCM (and then erase), they have various rates: mostly DSD64, but also some with DSD128 or DSD256.
Even if anything beyond Red Book cannot be heard, I would prefer to minimize resolution loss.
I can't find answers on the internet on the most appropriate recommended conversion PCM rates.
e.g. should DSD64 be converted into 24 bits-96 kHz and DSD128 into 24 bits-192 kHz ?
I have no idea...

I would be very thankful if those knowledgeable about this could help.
Already thank you, a merry Christmas and happy new year in advance,

I usually start with 88.2 kHz and then generate a spectrogram with sox:

sox *.flac -n spectrogram -o spectrogram.png

Depending on how that I looks, I often end up changing the final rate to 44.1 kHz.

If space is your main concern, why not compress with wavpack instead of converting?

Last updated 05/03/2024 If you are reading this you already know that DSD files (DSF and/or DFF) have rather big sizes and large collections of these require plenty disk space. Although the cost of…

wavpack creates APEv2 tag, which is not compatible with most devices.
