nice to see a proper open-source multitrack editor that isn't tied to one OS. how does latency hold up with lots of tracks?

i have not benchmarked the playback yet. the performance should be industry standard an not a concern.

the audio callback is lock free and the dsp is vectorised. i think you can expect very good performance. there is a dsp load meter implemented that displays spikes in the load. anyways... adding benchmarks is in my backlog.

is audacity not multitrack?

Yeah but it’s not very good, crashes often and has been acquired by a company pushing some online subscription

let's hope audacity and audionaut will happily co-exist and learn form each other.
