Hi Richard,

Composer has no .wav export function currently. You need to record to .wav via your sound card.

1. Install an audio editor such as GoldWave or the free Audacity.
2. Set up Line Volume or Stereo Mix for your audio editor.
3. Set the audio editor into record mode and start recording.
4. Start playback in Composer.

Make sure you never go above 0 dB on your level meters, but keep the volume peak readings just under 0 dB.

Once your .wav file is right, burn it to CD.

Best Wishes,

Herbert
