Of course, as far as LAME is concerned, adding a "-q 0" will increase
the quality.

But in fairness, I doubt that is what you seek.

Any radio ham or CB freak will tell you that you can improve
PERCEIVED quality (that is psychoacoustic trickery) by adding reverb
or echo to the sample. (Before compression, ?obviously?)
