DSFDecoder failed to decode .dsf file about sfbaudioengine

[sbooth]

The DSF decoder doesn't require a specific DSF format but the DSD and DSF decoders only work with ASIO output which is currently only supported for exaSound DACs. The DSF and DSD decoders produce raw DSD output which cannot be handled by Core Audio without wrapping in PCM using the DoP (DSD over PCM) decoder. I think you probably want to use the DoPDecoder class for this purpose, which will send PCM wrapped DSD to DACs that support it.

One thing to add: there is currently no functionality to convert DSD to PCM for general use.

where can I find asiosys.h and other relative header files?
thanks a lot!

[sbooth]

They are part of the ASIO SDK from Steinberg. You can download it from http://www.steinberg.net/en/company/developers.html

Hi Stephen, thanks for your help!
I can decode DSF file now by using DoPDecoder(I use SFBAudioEngine-iOS project download from this site and when tap "Play Test Track" button, playing time and progress slider go correctly), but there is no sound at all(seems some noise there), do I need to set output for the player?

[sbooth]

Are you using a DAC that supports DoP?

[pzs7602]

No, I just want to play dsf/dff audio file in iOS(iPhone/iPad) by using SFBAudioEngine, is that possible?

[sbooth]

No this currently isn't possible; SFBAudioEngine doesn't perform DSD to PCM conversion.
