Traverso DAW
Audio recording editing
software for Windows, Mac and Linux. 
Features
Instead of using menus,
submenus, and yet more submenus, all actions in Traverso can be performed
quickly by using the mouse and keyboard
together. (Though most actions can be done by use of a
menu, you can learn them by using the menu first, and then using
the keyboard action.)
Non-destructive
editing
When applying filters (like
LV2 plugins) or changing volume and panning, the audio sources and
recordings are left in their
original state.
Filters are applied while playing or exporting.
Virtually
unlimited track count
Traverso is a Multitrack
Audio Recorder, and let's you create any number of Track's you want.
Track's support one or two channels,
and any
number of Audio Clips, either mono or stereo.

Traverso will let you un/redo all the actions that change the sound
of your
project.

lossless
format) or WAV64, it's possible
to record
to any of the supported file formats,
including OGG and FLAC, but currently
not enabled,
please let us know if you
want to record to those formats as well.
On
the fly sample rate conversion

operation lets you use files with different sample
rates in
your project.
No need to convert your audio files
to the sample rate in use by your
audio card.
Multiple Driver Back- ends
There's full support for
ALSA, Jack (including transport control) and
PortAudio.
Lock less realtime audio
processing
To assure smooth non interrupted
recording/playback of the
audio, Traverso uses a (soft)
Realtime audio processing
thread without mutual
exclusion primitives. Audio
read/writes are done via lockless ringbuffers
providing an optimal
process execution path,
guaranteeing high performance
low latency operation. CD TOC creation, integrated
CD Burning
With the CD Markers and
Marker Dialog one can create
a CD table of contents,
and
