Hi all,
Are there any recommendations out there about which of the various
CoreAudio approaches one should use for an iPhone app that does some
simple multitrack recording/playback? Just the usual deal with
recording a new track while playing previously-recorded tracks
(possibly with effects). I have seen CA examples that use AudioUnits,
some that use the AudioQueue API, some that use HAL, others that do
not. I realize that different apps may have different needs, but are
there any rules of thumb about which approach I should take? I
certainly love the idea of using audio units for doing mixing, effects
and so forth (coding up a simple mixer with the audio graph APIs) but
I'm still a bit confused about the recording examples (something about
using the output device as input?) and the audio queue examples seem
much more straightforward. Can someone set me straight? Thanks much...
