Umik-1,change SampleRates ???

Hello.

Does anybody know how to really use the umik-1 at 44.1 khz samplerate? I can only make it work at 48khz.

While I'm waiting for the correction file for this latest Umik-1 batch, I'm trying to compare the mic with the iSEMcon I got for use with audiolense.

I can only measure with everything configured at 48khz.

I'm scratching my head on this now.

Thank you

Only seems to run at 48kHz on OS X (10.5.8), but runs happily at 44.1k or 48k for me on Windows 8.

For ASIO4All you would need to tick the "Always resample 44.1k <-> 48k" box.

Re: Umik-1,change SampleRates ???

Yeah that works but forces me to put the patchmix/e-mu also at 48khz for it to work, so not actually measuring everything configured at 44.1khz.

It seams 44.1khz is not possible with the Umik-1, it dies on me! I always have to Resample

The Umik specs does say 44.1/48 but I don't know how to change it to 44.1khz or I'm really missing some point somewhere ?

Thank you

The 44.1k to 48k resampling would be happening in Windows rather than in the Java runtime. When making measurements with REW use a higher ASIO buffer setting, otherwise garbage collection in the Java runtime could lead to interruptions in the generated or captured audio.

Re: Umik-1,change SampleRates ???

Ok, thanks for the warning, I'll make that change.
But in regard to true 44.1khz sample rate?

Not possible??

Thank you

Doesn't look like it, you'd have to ask MiniDSP.

Minidps updated Umik-1 specs... 44.1 is no longer supported and I agree.. It does not work at 44.1.

Problem with this is that I don't know if I'm happy with this specs change since I'm locked to 48khz and I like to keep things in sync. If i'm listening to music I use 44.1 filters and movies I use 48. Not happy at all.
