Re: Voicemeeter using two USB SoundCards set to 44.1KHz with slight ppm

Assuming A1 and A2 are both connected through an asynchronously USB interface, they will have different clock domains. Assuming A2 has a slightly higher clock rate (by a few PPMs), PC will have to sync them otherwise there will come a time A2 will not have Audio data to output. How do you solve that...

Re: Voicemeeter using two USB SoundCards set to 44.1KHz with slight ppm

Thanks for the fast reply :)
I am referring to a configuration in which A1 and A2 are both set to 44.1KHz but there is slight PPM between them due asynchronous USB configuration.
My understanding is that SRC will have to be enabled to compensate for the PPM difference.
Am I correct?

I understand that, my question is whether A2 output is a re-sampled version of A1...

I did, there did not seem to be a noticeable error.
Yet, I wanted to verify from a technical point of view rather than sound...

Re: Voicemeeter using two USB SoundCards set to 44.1KHz with slight ppm

My first sound-card is Traktor controller.
The second sound card will source the PA system through its AES/EBU output (same music data of course).
I am wondering whether sound quality is not affected by this setting, since re-sampling for the second sound-card is lossy.

Voicemeeter using two USB SoundCards set to 44.1KHz with slight ppm

My Setup: A1 main:ASIO Focusrite USB Audio Driver, fs=44.1KHz A2: USB asynchronous DAC, fs=44.1KHz Assuming A2 sampling rate is slightly faster than A1 (about 100ppm), at some point A2 will not have data. How is it possible then to have two outputs? Are you re-sampling A2 in a way that add/subtract ...
