Hi, An audio colleague asked me something regarding the sample rate conversion tab and filters He said that even if the sample rate conversion is off the sound changes when the filter is changed. I didn't knew that the filter section is available if SRC îi disabled. My logic (based on a limited understanding of audio conversion) is that when SRC is off (disabled) then the filter section is bypassed. I have tested on my setup and the only thing I notice is that the song played was 5-10 seconds rewinded. I don't notice anything else regarding sound quality. But I didn't test long, 2 separate songs. We also use HQPLAYER and don't want any other filters from Roon active. Can you please provide some clearance?
Great question. This has come up before, so we’ll answer definitively: when sample rate conversion is disabled, the phase filters are bypassed as expected.
The “pause” you hear when you change phase filters is simply a UI artifact to acknowledge a configuration change in the DSP pipeline. Roon will “pause” like this anytime the DSP settings are changed, even if a particular stage is not active.
You can always check the Signal Path to verify what Roon is and is not doing in your audio chain. The Signal Path is fully transparent to the digital chain, so any stage omitted there is not being applied.
Thank you and please reach out if we can clarify anything further.
