SRC EXT L+R (or individual) noise floor

Hi All,

Just received my DT. I immediately noticed that even with nothing connected to the inputs, if I record, there is a very “pink/white-like” noise that is recorded. Even with cables connected there is this noise underlying. Thankfully, once you record and the sample is normalized this noise floor is very low.

Anyone else seeing this? Just want to make sure I’m not the only one. OS 1.01.

Thanks!

Do you normalize when you record nothing ?

By default the DT normalizes so yes, the recording was normalized. But, you can actually see the meter hopping before you ever record which seems wrong.

I’ll continue trouble-shooting and try some different cables, etc. as well.

If you normalize noise it is normal ! The noise floor is the important thing to check.
I’d set auto normalize to off, if possible.

Same behaviour on Octatrack, without cables, if you normalize your record, you have a very nice white noise. Don’t need samples finally. :wink:

The more I play with it I think it likely is normal - but even so, would be nice the interface could filter out the display of it. Maybe it can be considered a bug :slight_smile:

I didn’t find it in the manual : can you disable auto normalization ?

I don’t believe so - I’d be willing to bet it might become an option one day though.

If you can’t disable it, I won’t buy it. :zonked:

This is slightly bugging me too … my recordings from the mixer have too much white noise for my liking.

pretty sure the noise is coming from your mixer.
the a/d interface in Digitakt is nice & clean.

could be that the output from your mixer is too quiet? This would explain that you can hear a noise floor after normalizing…

I notice this on the OT, the meters are going on the inputs when no audio is going through them. Always blamed the mixer.

not sure about OT, but on DT the input meter seems to be adaptive… so if there’s silence, it boosts the level so you can actually see the noise floor in the meter. Think this is so that you can better adjust the recording threshold…

I think it has to do with the variance in recording levels - say when I record a pad on the OP-1, and then a stab, the pad is much quiter so a lot more of the noise floor gets normalized … would be nice to be able to turn off normalize.
