Wasapi can not work as multitrack recording, but WDM-KS yes

[Dan Olaru]

I'm sorry, I can't record my band in multitrack session without WDM-KS driver, with my Onix Firebird soundcard (8 channels) in Win 7 or more. Why don't introduce this driver again in last edition of Audacity? Did you hope for that?

We trialed WDM-KS in an old version of Audacity, but found that many sound card WDM-KS drivers were buggy and could cause a complete system crash, so support for WDM-KS has been withdrawn from Audacity. There are no immediate plans to bring it back as we don't have a developer to work on it.

Maibe you can introduce ASIO. Many multitrack soundcards and DAW-s work with this driver.
Have all the licence for this?

Unfortunately the license for ASIO is incompatible with the license for Audacity. More details here: http://wiki.audacityteam.org/wiki/ASIO_Audio_Interface

Can Audacity 2.x record multitrack with WASAPI and other soundcards

The number of recording channels is entirely dependent on the audio device drivers. Based on posts to this forum, some devices are known to have multi-channel WASAPI drivers, and these work fine with Audacity.
