[FFmpeg-user] mono or stereo? ffmpeg converts or phone?

[Sean Darcy]

I have a bunch of lectures I need to transcode to play from the android 
phone, The lectures are in wav stereo format. The phone has only one 
speaker, so mono.

I want to transcode it for the most compression for a given bitrate; 
I've only got 16gb. So for a bitrate of let's say 48000, am I better off 
converting to mono in ffmpeg ( -ac 1 ) or leaving it stereo and letting 
the phone convert it?
