All of the analog/vintage "color" modes have some amount of noise, it's just most audible on the BBD mode with age turned up.chagzuki wrote: ↑Mon Sep 25, 2023 11:23 am A question about the 'age' parameter on Valhalla plugins, at certain levels or on certain delay types, or in certain era modes (or a combination of all?) it emits a constant background noise whether there's any signal input into the delay. Is there a rule as to when this happens? I notice in some projects some noise during a silent passage and track it down to a Valhalla delay... I wonder, wouldn't it make more sense if the noise was only generated when there was actually a signal being processed/a delay occurring? I can't imagine a scenario where it would be desirable to have a constant background noise, but of course it's often desirable to add some noise to the actual delay.
Edit, it appears to only be the bucket brigade mode, but not the BBDuck... which I guess makes sense.
Apart from being a part of the model, constant background noise allows you to get to feedback self oscillation with no input, which can make some fun feedback sounds.
