1. Record a podcast narrative using a microphone 1.1 Press the RECORD button and read your narrative 1.2 Press the stop button when complete 1.3 Play the recording and use the SELECTION tool to remove unwanted pieces of audio. 1.4 If necessary use the ENVELOPE tool to increase or decrease the sound level or the GAIN SLIDE at the left of the audio profile. 1.5 Select the SAVE PROJECT option and save your original recording before modifications are made.

4. Prepare the multiple audio files for integration. You now have a number of audio files. Note the sample rates (44100hz, 8000hz, 11025hz,etc.) for your audio files. If there is a difference in the sample rates then: 4.1 Go to the bottom left corner of the screen to the PROJECT RATE box and confirm or change the sample rate for your files e.g. 44100. 4.2 Select FILE and then EXPORT MULTIPLE.

Bouncing Two Stereo Tracks to One Mono Track Now we have the audio file open that we are going to edit. Next, we need to split the left and right channels into their own separate tracks and then convert them into mono tracks. Figure 1 shows the menu to split the tracks into the left and right channels. Select the title of the audio track (on my track it is labeled “harder”). Once the menu comes up, select the Split Stereo Tracks option. You should now have two separate tracks; you will use this same menu shown in Figure 1 again to change the two tracks to mono. Select the title of each audio track, and select the Mono option.

Figure 1. Changing the Tracks to Mono Doing this allows the two tracks to be mixed together. Next, we mix the two tracks together into one single track, which is called bouncing. Select both tracks; you can do this one of two ways. You can select the audio pane, which is right under the drop-down menu you used to change the audio track to mono, and then select the other track while holding down the Shift key. Or, you can go to the Edit menu, followed by the Select submenu, and then select the All option. This selects all of the audio tracks in the entire project. Either way works the same for this project. You then need to go to the Project menu

and select the Quick Mix option. This should bounce the two audio tracks into one single audio track.
