For my assignment 3, I convolved a series of impulse recordings with the quintessential audio clip of Dobby (the house elf from the Harry Potter series) being freed from his master (which I obtained a twenty second clip of from SoundBoard.com).

Original Audio Clip (Dobby is Free):

My two acoustic space IR recordings were taken by recording the audio of a balloon popping (with its accompanying reverb). The locations I chose to record were the women’s bathroom in the basement of Baker hall and the overlook present on the second floor of Baker Hall.

I then explored a little bit of what the Dobby recording would sound like when convolved with common soundtrack noises that might be present in a bad movie. Specifically, I chose gurgling water, seagulls cawing, applause, and crickets soundtracks that I downloaded from SoundBible.com.

After making these samples, I started exploring some of the built-in Max examples and ran into one named “convolution workshop.” A bit curious about what it would do, I merged our original convolution reverb patch this patch. Specifically, I pushed the “Dobby is free” audio and the “applause” IR through the original convolution and then pushed the result into a source filter convolution with the “Dobby is free” audio again. The result sounds significantly more noisey than the previous results.
