Post Production
These are my post production notes on what we did for the nameless developer podcast #1 so I can reproduce and tweak.
We talked over Skype. I fed Skype’s output to my Tascam US-122 USB Audio Interface device. I fed the output from the Tascam (my mic + PC line out) back into my PC. I used Audacity to record the signal coming in from the Tascam. I recorded in stereo with Audacity.
Using Audacity I split the stereo track into two mono tracks. After a lot of experimentation, I found the following worked out well for this recording:
Skype Track: Noise Removal, Low Pass Filter (2000Hz), High Pass Filter (400Hz), Hard Limiter (-2, 0.5, 0.5)
Local Mic Track: Noise Removal, Low Pass Filter (2500Hz), High Pass Filter (100Hz), Hard Limiter (-2, 0.5, 0.5)
Then I did some spot treatments to take out a few noises that the noise filter didn’t catch.
Exported to WAV and ran through Levelator.
In a new Audacity project, I put together my intro, music, and the Levelator-ed WAV. I made each track mono so the exported MP3 would properly end up with a 44,100Hz sample rate.
Exported whole thing to MP3 at 64kbps.
