internal sampling rate

Post by Harry Mudd » Thu Jun 25, 2020 10:22 pm

hi folks
I discovered a slighly audio quality loss when using VM with other sampling rates than 48kHz.
Is there a chance to see an update which will gain constant audio quality at 44k1 cause I record all my stuff in this SR.
The quality loss is not dramatic but with high frequency stuff there is some aliasing audible.

I have created 2 jpgs in PluginDoctor at 44k1 and 48k to show the difference of the audio quality.
There are no modules inserted I just conneted the input with the output.

Hi,

Thank you for the suggestion, I'll pass it along to the software devs!

I work at 96kHz. I don't see a problem with the harmonics analysis at 96kHz, but I do see a serious concern with the imposed filter applied at 96kHz. This seems to significantly harm signal above 10kHz. Cherry, why not use a Nyquist-style filter instead of this super gradual one? I've included a suggested filter based on the iZotope RX SRC.
