Once the tracks have been mixed down to stereo, applications such as Steinberg’s Wavelab and Apple’s WaveBurner can be used to compile the stereo songs that make up your album. This typically includes drag and drop changing of the running order, adjusting ‘leader tape’ gaps between each track, or creating cross-fades between tracks. In addition, these applications allow you to prepare your music for CD duplication using the Sony ‘Red Book’ standard ‘PQ’ encoding of trackmetadata.
