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.

Using nokiaaacenc, you could probably directly save as AAC >> What about a real free format like OGG vorbis? > > Um.. speex?
