4 – Create your Voicetrack
OK, so you’ve recorded your Voice Prompts, and an Introduction for each week, and made your soundtrack, so you have a good idea of how Audacity works. Time to put your voice track together.
1. First, using your printout of the C25K program, you’ll want to write down the time cues for each run. For example, for week one, you would write down something like this -
- 0- 15 Introduction
- 2.45 – Pause for Stretches
- 5.15 – First Run
- 6.15 – First walk
- 7.45 – Second Run
Etc.
Of course, this assumes that you have a 15 second (or so) introduction and you start walking at the end of it. Having these written down will really make it faster when you come to put together your tracks.
2. Open Audacity. Import your Week One Introduction.
3. Import your “Pause to stretch” voice prompt. It will appear below your introduction.
4. Import your “It’s time to Run” voice prompt. Use the track toolbar on the left side of the track to re-name the track “Run 1″ This will help you to keep track later.
5. Repeat until you have eight Runs, and all the appropriate walks and other prompts as per your time cues.
6. Click on your “Pause to Stretch” track. Note that on your time cues sheet, this track should be at 2.45 minutes, so use the “Time Shift tool” (Time shift close) to move the track until it starts approximately at the 2.45 minute mark.
7. Use the Zoom tool to zoom in so that the time bar at the top of the screen shows one-second intervals.
8. Using the Selection tool, click on the “Pause to stretch” track until the cursor is lined up with the 2.45 mark. Keep trying until you are as close as you can be.
9. Use the time shift tool to line the track up with the cursor.
10. Repeat with each track until all your voice prompts occur at exactly the right time. Note that with your “Start to Run” track, the GO at the end is louder and looks distinct from the rest of the track. Try to line that bit up with the cursor.
11. Go to File and Export your Track as an MP3 as shown below. Save the track in a folder called “C25K Voice Tracks”
12. After you’ve exported the file go to the folder you exported it to, and rename the track “Week 1 Voice only” Or something along those lines.
Tip – You may want to load these voice tracks onto your MP3 player as well as the ones with music. Sometimes, like when the music in the gym is good, or you want to listen to the birds in the morning, it’s good to just have the voice prompts and silence.
13. Repeat this process for all nine weeks. Don’t worry, it’s a lot faster once you get the hang of it, and after the first few weeks there’s less intervals, so that makes it quicker too
