Hi Marcio Frayze David, Before I install a "native" Haiku installation (I just used it under VMware) > I would like to know: is Haiku ready for simple sound edition? I have played around that, Haiku is not ready to record in real time due to some latency problems. Is there a good hardware (audio) support? Yes, we have many native drivers and a port of OSS, usb/firewire audio devices are not available (a native driver is requested). I suggest you to install Haiku, usually the system run better on native hardware than in vm. What (free and open, if possible) softwares should I use? I don't want > anything too complex, just want to record on multiple tracks, that's all. > BeAE is an audio editor for Haiku. You can install BeAE using the installoptionalpackage command from Terminal, some apps are available to haikuware.com, i suggest to take a look. Cortex is a "media_kit gui", it allow you to control any node in the media_kit (it is installed in any Haiku build). http://haikuware.com/directory/multimedia/audio/audio-editing/ Regards
