iirc it is the same as audio volume (e.g. 1=unmodified, 0.5=multiply by 0.5, etc). 1 Comment...

Question: Hey Justin, which audio backends do you use for REAPER? I've been looking for something cross-platform that isn't locked with licenses, so far it's looking like supporting xaudio2 initially and adding additional support where needed, I'd assume you'd fairly heavily abstract your sound api? Thanks

hmm for what? code? 1 Comment...

Question: I hope it is ok to ask this here: in REAPER, if i have, for example, 50 tracks with lots of inserts, some with sends to each other, some folders, and all their outputs are being sent to 24 buses. And I use ReaStream/ReaRoute on those buses to send to another DAW. How is the latency compensation calculated? Will audio arrive on perfect time or I should be cautious? I will be running some tests but I'd like to understand how this works a bit more. Also, is Reastream sample-accurate with a cabled LAN? Thanks!

definitely better on the forum, but in general reastream isn't really good for this. If you do it, make a single 64 channel reastream instance, send everything to that, then have that send to the other place. 5 Comments...

Question: hey justin- are you aware or keeping up with serato "stem" tech? a few other wares are doing this-- its probably some fft thing which will seperate music into its composition parts..drums,vocals,melody,bass.. could cockos champion this idea?? primer here> ( youtu.be/J2L5jyiuT7A)

I would like to say that I wouldn't, but it would be so obviously an over-valuation that it would be hard to pass up. But I wouldn't keep the money. 5 Comments...

Question: Is it in your plans to have a UX/UI/Workflow redesign for Reaper 7.x? I love Reaper, I have a full license, but it would be amazing to have it more natively integrated with extensions and redesigned visually....Impossible to explain without making references to other DAWs :)

you can email support with your requested changes but you should include the explanation for the changes, and we might consider it, though as our terms are very reasonable and widely accepted we might also not. 3 Comments...

It is compiled. If you carefully optimize the code it's probably about half the speed of typical non-SIMD C++. Some things are slower, e.g. memory accesses using [], since it involves bounds checking and conversion to integer, etc. 1 Comment...
