Hi Deane

Record as a WAV file with the levels peaking just below the red, (Some of you previous posts have exceeded this and caused distortion/ compression artefacts) then transfer the files over to your PC and use Audacity to normalise them http://audacity.sourceforge.net/ and also convert them to mp3. (Use 256K settings when converting to mp3 to minimise the losses incurred when converting to mp3 or alternatively convert to FLAC as this is a lossless compression format)

Hope this helps

Bill
