Rust equivalent

[xenide]

hey I'm also trying to build a rust equivalent, to do DSD over DoP. But somehow it's not working. Would you be interested to look at some code to see what I'm doing wrong?

Thanks!

If you want to convert DSD to DOP for playback:

• On the Windows platform, you must use WASAPI exclusive mode.
• Set the PCM sampling rate (for example, DSD64 requires a sample rate of 176400).
• Encode DSD into the DOP format (for details, please refer to https://dsd-guide.com/dop-open-standard, or use BASS at https://www.un4seen.com/doc/#bass/bassdsd.html).

ah you know, I'm using the rust cpal library. And in its current state it doesn't support 24 bits, only 32 bits. But DoP requires exactly 24 bits right? I think this may be the reason why it's not working

You're right, on Windows, DOP playback only supports 24-bit format because it uses WASAPI in exclusive mode. I'm not very familiar with the Rust programming language, but after looking at the implementation in /src/host/wasapi/device.rs, it only implements WASAPI in shared mode, so this implementation cannot achieve DOP playback.
