Re: Recording calls

The problem is to find a compromise between:
a) CPU/power usage
b) Encoding efficiency
c) Playback capability
d) API availability

Due to a) and d), I'm only looking at the gstreamer encoders available
on the N900. Du to c) I have dropped the ANB and AWB codecs from
evaluation - I was unable to quickly find a standard software for
playback on Windows (e.g. WMP or VLC bot failed)

Tonight, I'll try low bitrate AAC as it is probably a good compromise
between these factors. I will also try speex, as it's on the N900 by
default and technically ideally for encoding this kind of audio.
However, I'm not so sure about playback capability on Windows :-) Is
Speex on the N900 using the DSP? Because I guess that all NokiXXXenc
are, e.g. the AAC one.


Thanks
