These are samples of audio post-processing I’ve done, in order to get a cleaner sound. The first pair of sounds come from an old, beat up 45 RPM record designed for training your canaries (yes, I can vouch that this actually exists!).
The second pair of sounds come from a 48-Hour Film Festival project I was involved with, where the filming was done on location in an office building. Because of the time constraints involved, there wasn’t little time to prep the location for clear recording, so there was lots of background noise from machinery and the building’s HVAC system.
The last pair of sounds came from an interview that needed some clean-up to get rid of some background hum and as much of the reverb as possible.
