What format does ardour use when recording raw data?

In other words when I arm a track and hit record, how much storage space is used in the raw recording/tracking. Also is this same data volume summed for each track (ie 2 tracks twice the storage space)

I assume it depends on the jack sample rate and bit rate, but I know there are different lossless formats so I wanted to check before I over run my Mac’s harddrive.



Ardour uses an uncompressed format to store audio in. You can select which format specifically in the Options menu. Sampe Rate is derived form whatever Ardour(And Jack thusly) is running at.

And yes obviously for each channel you record you will need to add that to the equation when figuring out disk space.
