I'm bringing here an issue I'm a bit lost to solve on my own. Information : English is not my mother tongue.
I use Bela as a multi-effects processor for a beatboxer. It is enclosed in a sort of saucepan and interactivity is provided by pots, buttons and some sensors. There is an input which is a XLR to unbalanced mono and an output which is mono Jack.
My project is not a prototype anymore and I'm reaching the end of it.
Unfortunately, when the musician is including the "saucepan" into its sound chain, there is an undesirable noise heard which makes the whole thing unusable. It appears even when the signal is not wetted by any effects and it's especially strong at attacks' times.
Before detailing here the entire technical configuration and presets of the whole project (I don't really know where to start from) I wanted first to make you hear the thing in the eventuality it makes you think something about...
Pay attention to the little "metal" sound which goes over pops (a hand hitting mic).
I really hope you can help me with that, feel free to help me describing more what informations I should bring on...
