Hi everyone,

Just a quick question: if I set a gain (negative), say -3dB in Korg AudioGate while playing a .dff file, will the output still be "bit-perfect" (or of the same quality, if you will) or will AudioGate degrade the signal quality because of the gain?

The reason I'm asking this is because with the gain set to 0, I get clipping at the output. At first, I assumed this was due to bad mastering and compression, but apparently with the DSD-to-PCM conversion, this may not be the only reason, due to the sheer nature of the DSD recording.

Thanks.

P.S.: I'm using an ASIO driver. AudioGate is set to PCM sampling rate of 192kHz.

As i understand this you never had "Bit-Perfect" output. Applying a gain of any kind shouldn´t be a problem at all. The main problem will be how Korg translates the DSD data to PCM.
Normaly DSD should be mastered more silent so if it clips i wonder if Korg already applies a gain.

Right. So the gain should be no problem.. Thanks guys.

Yeah, I know I can never get "bit-perfect" DSD audio since I don't have a DSD chip on my sound card. What I meant was audio of the same quality or about the same quality (since 192kHz is already a very high sampling rate)... Regarding the AudioGate, they say it is probably the best (or among the very best) DSD-to-PCM converter, so I have no reason to believe the output is not very accurate.

Regarding the gain: yes, the question remains whether AudioGate applies a gain by default when doing DSD-to-PCM conversion and if that is the reason for the clipping. I guess there's no way to tell for sure...
