I keep reading "AMR" everywhere.. all I know is that it's a file extension for some kind of sound file. Is this correct? What about AMR? What is it specifically, what is it used for and what's so special about it?

Thanks

It's the file type used for se's when oyu record voice. I'm not sure about technical details... but it seems to be quite high compression, because they sound terrible. I don't think theres anything particualrly great or special about it though... It's also in mono, on my k750i at least...

yes, indeed, AMR works in low frecuencies. I have this AMR converter and to convert WAVE to AMR, the WAVE file needs to be in 16 bit, 8kHz sampling frecuency. wiki:

Thanks! The two posts summed it up nicely. AMR? Nothing I have to worry or care about even remotely

Thanks

Unfortunately I do use it alot. I use to record my university classes.
But the problem is that W800 media player doesn't support AMR files, so you can't listen them on your phone...
Well, actually you can listen but without skipping and pause functions, so for long recordings it is useless
