I'm encoding at around 16kbps/24kbps in Mono at 22khz. I'm trying to achieve something like FM radio quality.
Sometimes I get close...

I've tried lame VBR with maxbitrate and more recently have tried ABR but I'm not sure the VBR wasn't better?

Does anyone have any tips on how I can improve my encodes in Lame? Should I add a highpass filter? What do others think of ABR vs VBR? I know ABR is recommended for low bitrates...

I know this is really far away from the usual Lame stuff but I hope people might be able to help a bit anyway!

love

While most of the stuff I'm working with will be mono all the way, that is still an awesome suggestion that will come in very handy!
THANKYOU! Very much appreciated!
