resampling leads to pops
« on: April 24, 2011, 07:54:33 am »

high everybody
when I use "resampling" (192) in DSP, I clearly hear pops, like playing good old vinyl, on ripped cds as well as on (untouched) highres files. I would not mind using native resolution if my dac would also accept 176,4 files, but he doesn't and I have some of these. And besides those pops I would give software based resampling a serious try. So, any solution to this or did I only do something wrong?
I use WASAPI event, buffering 500ms, prebuffering 2s.
My system is win7/intelbased, fanless audio only, soundcard used at present RME HDSPe AIO.
good advice would be very, very appreciated

That's probably coming from your device's driver. 

Try the other WASAPI.  Try other audio modes.

Try a lower sample rate.

Please see "Audio Output Modes" on our Wiki.

Make sure you're using the latest build of MC.

Hello JimH
many thx for your advice. Meanwhile I tried the following:

Wasapi: much worse, in all DSP/output adjustments

Kernel streaming: did not work at all.

Asio: sounds very good with native files except 176,4 (not played at all.) with resampling added the pops reoccur in every format.

I retried Wasapi event and found out that with all sources resampled,  that pops occur in all formats and with all output sampling rates. With resampling reduced to "... sources greater than 96" everything is fine except 176,4, the pops are there.

I use MC16.0.72.
I played a little arround with adjustments In RME soundcard which made no differences so far.

High
new (beta-) software of soundcard (rme) solved problem!
