is the balance set to center?
cause usually that's the problem

we have left and right channel.
left channel volume is 50
right one is 100
and i hear the song only from the right channel

If you just want to change it temporarily (in an MP3 player) most programs like WinAmp have a slide bar L<-->R.

If you want permanent changes you need to decode it to WAV and work with the resulting WAV. For that I recommend a wave editor like AcidWAV.

already edited with goldwave.
i selected the right channel->copy->selected the left->mix.
but i don't know if this is the best method because the left channel with volume 50(for example) now is 110 compared to the right (100).
i didn't found function like normalize but to make the volume of the two channels equal.

it's not such a serious problem..... just ajust the balance....
or you can convert it to WAV and use any WAV editing program to change it to mono...... or if you want the stereo effect, you can just raise the volume on the channel you don't hear......

what about the quality if i raise the volume of the left channel from 10% to 100%?

well, you're gonna just have to try it to find out......
try it. if you don't like what you hear, just change it back to the way it was and change the balance...........
