Audacity Forum

Dear Audacity community,

I have asked about this on the Native Instruments support forum too, but I haven´t received a response yet and I think this probably has more to do with Audacity then it has to do with Native Instruments. (For the Native Instruments support forum post see: http://www.native-instruments.com/forum ... hp?t=91010)

I want to record with a 96000Hz sample rate. When I set the sample rate in audacity to 96000Hz and in the audio 4 dj control panel to 44100Hz, it all works fine and i shows a nice spectrum in audacity. But when I select any other sample rate in the audio 4 dj control panel audacity gives me an "Error while opening sound device. Please check the input device settings and the project sample rate."
Visual representation of the problem:
Situation 1, working (96khz in audacity, 44100hz in audio 4 dj control panel):

audacity


audio 4 dj control panel settings


audacity working

Situation 2, not working (96khz in audacity, 96khz in audio 4 dj control panel):

Same audacity settings


audio 4 dj control panel settings


Failure

Thanks alot if someone could help me out with this.

Will it do 48kHz on both?

It works with any bitrate set in Audacity. But as soon as I change the bitrate on the audio 4 to anything other then 44100 it gives me the error upon clicking the record button.

It sounds like this may be due to a limitation of the Windows drivers for the NI.
The NI Audio 4 probably uses ASIO drivers by default, but due to licensing restrictions Audacity does not ship with ASIO support, so it has to use native Windows drivers, which may be limited to 44.1kHz.

This would give you a few options:
1) look for a driver update for the device.
2) Use a program that supports ASIO to record with. (You can Import the recordings into Audacity for editing)
3) Set both the device and Audacity to use 44.1kHz

I would try option 1 first, and if that did not succeed go to option 3. Unless you are editing audio for video you will probably want your final production at 44.1, so you will not be losing quality by doing the whole production at 44.1

Thanks for your useful reply!
Unfortunately, I'm using the latest version of the device driver and it's working. Can you recommend me a program that supports ASIO? And the 3rd option is not an option since I really want to record in 24/96, I'm digitalising my vinyl, just so you know

Audacity can support ASIO, but you would need to build it from the source code and my guess is that you'd rather not do that (I tried that myself, and it's a right pain in the you know what).

Have a look at "Wavosaur" and "Reaper". Wavosaur is free for personal use, Reaper is not free, but it's an excellent demo, and very fair licensing terms. I think that they both support ASIO.

Oh yes, and one more; have a look at "Krystal Audio Engine".
