Next, click on Configure Encoder to change the settings for the LAME MP3 encoder. By default, it's going to be set to Standard, Fast . which doesn't give you a very high quality MP3 file. The second thing you'll read is that you should never convert a lower bitrate stream to a higher bitrate stream and hope that it sounds better. You cannot gain quality by increasing the bitrate. This is exactly correct. You will actually reduce the quality of your MP3 file if you try to convert up the bitrate.
