Re: Question about OSX audio routing

[Raul Bonell <raul.bonell@gmail.com>]

... not much related but i need to know.

if i try to capture through soundflower, and providing that
soundflower always sends 32bits streams, my ableton's impro's into
logic (under leopard) ... does this implies that logic will truncate
from 32 to 24 bits, since logic can't open 32 bits files? ... i know
logic operates with 32 bits internally, but what about recording from
soundflower? is ableton really sending 32 bits in realtime? any
workaround per?
