I’ve been recording my favourite radio program using mplayer (dumps to wav), then encoding to ogg. For some reason, probably related to the web broadcast, the result is far from satisfactory. In the case at hand, the right channel is clearly at a lower level than the left - it sounds quieter, and Audacity shows the same waveform, though with a tenth of the amplitude.
Since this is radio, I’m not overly concerned with quality. I would like to have the same volume on both channels, though. I thought about converting to mono from the higher channel, than to dual-channel mono. Notice, though, that I still have a stereo recording, its simply that the right channel has a really low gain.
What would be you suggestion for equalizing.adjusting the channels?
