Up until now, most of the editing you've done has been in the Waveform Editor, focusing on a single file at a time. Since all the clips for the podcast are edited at this point, it's time to assemble them into a single file — which can be done by creating a new multitrack session, and working in the Multitrack Editor. A multitrack session allows us to work with multiple audio clips at the same time, with different audio clips on different tracks. If you've worked with layers in other programs, such as Photoshop and Illustrator, tracks behave similarly to layers in that they can each hold separate information and can overlap each other to create interesting effects.
Before you start assembling the podcast, or any multitrack session in general, you'll want to have a general idea of how the clips will be assembled — in other words, what order the clips will be in, which ones might overlap, when music might fade in and out, and so on. The plan for the Tech Talk podcast is as follows:
- Start with 10-15 seconds of intro_song.wav before music lowers and intro.wav begins
- Once intro.wav ends, let intro_song.wav play until it fades out
- First segment: tech_news.wav
- Second segment: tech_word.wav
- Third segment: favorite_app.wav
- Fade in outro_song.wav, play for 5 seconds before music lowers and outro.wav begins
- Once outro.wav ends, let outro_song.wav play until it ends
Let's create a new multitrack session, and start building the podcast.
