I’m not sure that Audacity can process live audio. If it does, I’ve never tested it. For reference, the hosts that get tested the most here are:
Windows
- Ableton Live
- FL Studio
- Bitwig
- JUCE Plugin Host
- VSTHost (Seib)
Mac OS
- Ableton Live
- Logic
- Audiomulch
- Bitwig
- JUCE Plugin Host
I have been also testing in Reaper a little lately to fix some timing issues that came up. It’s not the easiest instrument plugin host to use, but if you’re mostly doing audio recording I would definitely look into it.
The JUCE Plugin Host is not a full-featured program, but it starts up quickly and is very handy because of that. Unfortunately you can only get it by downloading JUCE and compiling it. I would have to read the current JUCE license carefully to know if distributing it as binary is allowed.
I don’t yet offer a native Linux version of Aalto but I want to.
