As I recall, when setting conversions, you are supposed to select a format and bit rate. Then Replay Converter converts to that format and bit rate. I have noticed if recording a 128KBPS source and converter is set to 320KBPS, the result will be 320KBPS even though the audio quality will reflect the 128KBPS Quality. The result is a larger file with lower quality audio. Is there a setting so that you could select to simply preserve Original Bit Rate when converting?
