Since some time, the macOS CI run via github actions usually gets killed before it is finished.

We should try to make it faster so it doesn't get killed by github for running too long.

Likely, it is not the tests taking too long, but some preparational steps.

I am working on creating a WandbCallback for Weights and Biases. I am glad that CatBoost has a callback system in place but it would be great if we can extend the interface.

The current callback only supports after_iteration that takes info. Taking inspiration from XGBoost callback system it would be great if we can have before iteration that takes info, before_training, and `after

As peak value I expect app. 50'000 messages per second.

With several settings I reached up to 20'000 msg/sec. but that is not sufficient for our life traffic. The MongoDB ho

hi,
as you know, in SoLoud, the number of filters are limited
we should implement more like different reverbs, fir and irr filters, (these could be used to implement HRTF support), Chorus, One Poll, One Zero, Pole Zero, Two Pole, Two Zero, etc
a library exists called stk under zlib license which already implemented these maybe we can implement some of these out
