DirectSound

[Sveni-Go]

Hi,

No DirectSound Option in Playback/Device.

When i change Wasapi then i can't change Stereo or 5.1 Surround. Why ?

You can change this in Windows

DirectSound is unavailable in Windows 11

Is there a reason for this? Because AIMP runs just fine with DirectSound on Windows 11 under compatibility mode.
Surface Pro 7 cannot change the output to 44.1KHz, so I rely on DirectSound in order to avoid having AIMP to resample everything to 48KHz. I know the device will resample everything to 48KHz before the final output, but I don't want AIMP to do this resampling.

Soolo, I am not claiming to hear any difference, because I cannot. That is not my problem, I don't want AIMP to do the resampling, and I also want 32-bit float audio. DirectSound is perfectly functional on Windows 10 21h2 and Windows 11 21h2, I don't understand why is it even a debate whether to remove a perfectly functional option.

But our resampler has better quality than DirectSound's one. DirectSound is just a backward compatibility interface that emulates old API based on new WASAPI.

I also want 32-bit float audio

for what?

I am not arguing that. Personally I can't hear a difference. It just makes no sense to me as to why this option needs to be removed in W11. It works perftectly, even in W11.

Better/faster anticlipping than the implemented version under Settings>Transform.

Really?

Really?

Well, on my PC with an i7-11800H TaskManager will report 1 - 1.3% CPU usage while AIMP is using the built in anticlipping. Relying on 32-bit float audio for anticlipping AIMP uses less than 0.1%. It's not much, but I think 32-bit float is more efficient.

best anticlipping - turn down the volume

Quality != Cpu Usage

Maybe.
