EXPORTING YOUR SESSION
Getting your session ready for podcasting.
1. Once you have finished recording, you will need to create a
Mixdown of your session so it can be podcast.
Click on File | Export | Audio Mixdown.
2. You will see the window to the right.
3. In the File name field, type a name for the audio file Mixdown (name of your
session) and select where you would like to save the file.
4. For Files of type, select MPEG Layer 3 file (.mp3). This is the format that you
will need to save to in order to be able to upload your podcast.
5. Under Attributes you can set the quality of the Mixdown file. Keep in mind that
higher kBit/s rate and sample rate (kHz) will result in better quality audio but slower
upload speeds. Also note that speech can be discernible at much lower bit and
sample rates than music so if you are planning on including music in your podcast,
try using 96 kBit/s rate or higher.
