Just posted this on the RME forums, maybe someone here has an idea about what is going on ?

Tried something else today, recorded some low frequency sine waves with CoolEdit - same problem, noise is present in the peaks of the sines, so on top of a 47 Hz bass tone I hear pulsating noise. Better audible when the frequency is lower, but still audible on 60 Hz sine too, for higher frequencies it gets masked by the tone, and the tones are getting too loud for my ears then too. So its a small effect, but I would like to know what causes it.

RME gives no reply BTW .. damn .. I could make interesting music with some effort showing the effect Laughing

Welcome to the wonderful world of RME support, I have had the misfortune of dealing with their hostile 'support' before.

What was your issue?

Anyway, yes it was a rude reply.

It was some issue with the OSX kext, I can't remember exactly but I do remember they were arseholes.

WDM? Wavelength division multiplexing??? With the RME? Uh? Seriously?

I have had absolutely no problem with my RME interface at all.

BTW, I hope you didn´t mention the war when you messaged product support at RME.

I'm sorry .. I may have used some stupid word or something, and I indeed really have no idea about driver models.

But instead of giving silly replies .. could you maybe just try to make a say .. 30 Hz full amplitude sine wave play that and tell me if you hear noise on that when you listen with headphones at a level of say - 12 dB .. as that is what reproduces it here.

And yes, that is pretty loud, don't try it with your favourite headphones maybe and dont try it with frequencies of say 100 Hz, you ears wont like that.

Is RME some religion or something? djeez.

Tomorrow... later.. late here now.

There are very few headphones that will play something like that in a way that does not distort.

I only have favorite headphones. Beyer 770 Pro and AkG 271s. The bad stuff is gone years ago.

It is not distortion, it is noise.
