Audio Arts - Week 6 – “Production: Outside the Square Pt 3” – 08/04/08

First up this week I have recreated the ‘one sample triggering the output of another’ scenario, adding a little effects automation. This gives a Lo-Fi audio effect similar to a distant motor vehicle with a loud stereo moving gradually closer. After a failed attempt to have the bussed audio triggering stabs from a 60 Hz signal hum (even after recording the hum to a track and using the playback file) I have duplicated the audio file to be output via the opening gate, and pitch-shifted it down instead.

Secondly I have taken a bass heavy drum loop and attempted to make a musically pleasing but less bottom heavy version. The original is in the first four bars of the file. To reduce the bass dominance I have combined use of the Lo and Hi frequency filters in the Pro-Tools Gate and Std Compressor. The finished product was then duplicated and used to trigger itself with sharper attack to make up for some of the lost ‘stabbing’ effect.

Lastly is an example of extreme compression of a dynamically diverse file. The image in this post shows the before and after effect of five compressors utilising sequentially diminishing threshold values.
