AFAIR and according to http://www.wikipedia.org/wiki/Sampling_frequency the phone uses 8Khz, if the phone
is good enough for you (and don't consider noise, etc., that's unrelated), it should be good enough for voice. My experience is similar, as long as I am recording voice, I can downsample as far as I can (at least with the original archos FW) and hear no difference, I can also compress a lot (I think I used the lowest level once). AFAIR phones uses 64kbps PCM - and that means 8 bit depth (I ran across 32kbps ADPCM too), and that usualy seems OK to me, voice conferencing and VoIP usually go so low that it's scary and so did early cell phones.

Just don't try to listen to music over the phone...

I think you are asking if YOU would ever need to use them, and my response
is that if you are just ripping CD and encoding MP3, stick with 44.1
sampling and set the bitrate as you see fit. I can't answer about
recording voice with the Archos -- any ABJR owners care to chime in with
some practical advice?
