debugging an app
I'm trying to debug a program that page faults on me, and I'm actually
quite keen to have a go at fixing it myself.
Unfortunately, I seem to have fallen at the first hurdle: I can't make
good use of the debug messages.
Background:
The program I am attempting to run is TrackLogs
( http://www.tracklogs.co.uk ). Installation went fine and on first run
I got the licence key dialogue,

low-power real-time embedded speex implementations
Does anybody have experience of implementing Speex encoding on
low-power, low-cost bare-metal embedded hardware?
I'm trying to get a feel for minimum possible hardware upon which it is
possible to get a reasonable working implementation of Speex encoding.
I can find little in this area on the website or via Google.
Thanks,
Henry

Denoise causing drain pipe effect in audio
...e is linear,
then JM has already done the work for you. Just use the AEC and plug the
"noise" microphone into where you would normally plug in the speaker on
the AEC (and delay the primary microphone by at least the speed of sound
time between the two microphones).

Denoise causing drain pipe effect in audio
Hi Jean
Thanks for the reply.
We expect to use the codec in an environment where we expect very high
background noise where high noise suppression will be needed. In a
situation like a soccer match.
Is there a way of retaining high noise suppression and still getting
better audio quality. Your pointers will be of great help.
Thanks,
Gurinder

I hope people don't resent me making a point on this, as I don't
actually know how the noise suppression in speex works, but I have some
knowledge in the area of noise suppression.
