Can these 10 steps for creating a podcast episode be automated? This is my first time trying to put together a recording of something which will become a podcast, and it seems like I have 10 "post processing" steps which I am currently doing manually.

It's entirely possible (in fact, it's likely) that I'm doing this in a way which is much harder than it has to be, but I don't know how to automate and/or simplify it. I'm hoping others who know more about this process might chime in and tell me how to make it simpler.

I'm starting with an AIFF file which has to be edited (cutting off time at the beginning and ending). This strikes me as the only step which can't be automated.


Edit AIFF in Fission to just contain the recording
Export as AIFF
Open Intro (a pre-recording mp4), Outro (same), and new recording (AIFF) in QuickTime7
Create new document in QuickTime7, and then Copy/Paste: 1) the Intro, 2) the new recording, and 3) the Outro.
Export AIFF from QuickTime7
Open AIFF in Levelator
Import leveled AIFF in iTunes
Export leveled AIFF to MP3 (iTunes) at a certain bitrate
List item
Add tags to MP3 (iTunes) checking to make sure I'm using same tags I used in previous episodes in all required fields except for the episode title which is different.


It seems like steps 2-10 should be something I can automate, even the tagging, except for the episode title, which I can manually add before I upload it to the server.

So how can I automate this, or otherwise make it easier / less error-prone?
For a good summary about how other people do it see How we do our home work which documents how the Home Work podcast gets recorded and post-processed:


QuickTime for audio recording
GarageBand for audio editing
Levelator 
Sound Studio to adjust the sample rate, mix down to mono and add metadata


Depending on your setup and your quality requirements you can at least combine #1 and #2 by recording directly in GarageBand and also add intro/outro parts.
