Hi,
Can you back up your claims that pulseaudio uses less CPU than JACK ?
pulseaudio cannot do wonders, if mixing is required the code must sum
up the inputs, jack does this
already in the most efficient manner and one can easily add ARM vector
code to speed it up.
I mean if battery is a concern th

The N900 already sucks batteries like mad. JACK is a no-compromise
low-latency pro audio server, and does it at the exp

Hi Benno,
I think you would probably recieve better answers if you did two things:
1) split your points up into logical groupings
2)
Hi all,
I'm writing an interactive app on the N900 with PR 1.2. which captures
audio and analyzes it.
I used QAudioInput and while audio capture works, is has an EXTREMELY
high latency, several seconds, (around 3-5secs).
I tried several sample rates, 8000, 44100, 48000 Hz, tried with small
buffer
