[maemo-developers] [maemo-developers] microphone recording quality

[From: Andrew Barr]

Hi, I notice that apps recording from the microphone input--Maemo
Recorder in my case--are limited to a sampling rate of 8,000 Hz (I
looked in ~/.gstreamer-0.8/registry.arm.xml (or whatever) to determine
this). This is okay if there is little to no background noise (I am
recording class lectures), but if there are papers shuffling or excess
talking the main voice can get very hard to follow. Is it possible to
increase the sample rate, say, to 22,050 Hz, where the GNOME Sound
Recorder is set for "voice" quality? This works quite well but
unfortunately requires my Thinkpad to be fired up :(. What's more, my
Thinkpad doesn't have the battery life of the Nokia, especially with
WLAN on. I have a 1 GB memory card so space is not really a concern
(typical .wav files from one session with g-s-r on my laptop are ~230
MB).
