I’ve a little note on my desk from last time I had to clean up a dodgy sermon recording. It was a spur of the moment idea to record onto the laptop, little did I know that the laptop had a built in microphone and so recorded not only on the line-in from the mono out (post-mix) of the mixing desk but also the hiss, flutter and buzz of the laptop via it’s own mic.

Here’s what I did in audacity to get a bearable result:

1.  Noise removal using a “silent” section as the noise sample
2. Effect > Glame, Low-pass (not butterworth)filter: 4800,  10poles
3. Dynamic range compress: Threshold -30dB, Ratio 3:1, Attack 6.2
4. Split new (to section up as “tracks” of a reasonable size to be compressed and emailed)
5. Export multiple to variable rate MP3

That may not help anyone, but I can chuck that scrap of paper away now.
