Deck and Peak are complimentary applications. Using them together gives you much more power and flexibility than using them separately. By combining the two you get the multitrack mixing capability of Deck, and the precision editing and mastering tools of Peak. Taking the band example used in the Deck section above—you’ve recorded your band, but now you need to turn that recording into something that can you can deliver to someone else. You can use Deck to turn your multitrack mix into a stereo file, and then open that stereo file in Peak. Once it is in Peak, you can boost the levels of the audio, create CD track index points, burn a CD, and convert to mp3 to be posted on the Internet. Using Peak on your Deck recordings allows you to make edits to the whole mix and finalize the file for delivery. This process is commonly known as mastering and gives you a much more professional sounding result.
