Homework 5: FFT-based Real-time Tracking
To create the first free recording, I played an portion of "Safe and Sound" on the guitar. For the FFT, I used the multiTrackers transformation with a StifKarp, which created a neat combination of strings in the output sound. The cascading StifKarp made the somber song sound even more eerie and ethereal.
For the second free recording, I used a combination of hand whistling, snapping, tapping, and clapping to create a more rhythmic sound source. While the first recording focused on melody, the second recording involved more rhythm and syncopation. I ran the recording through an amplitude frequency tracker with the BeeThree unit generator, which chose because it created a sharp buzzing sound to highlight the rhythms.
For the rhythm recordings, I used the output from Homework 3 and ran it through an amplitude frequency tracker with modified parameters. I chose a Saxofony as the first unit generator, which gave a deep, grumbling sound. I then used a TriOsc as the second unit generator to create a much sharper and crisper rendering.
For the scored sections, I used two different clips from the nature-15 recording. A sketch of the track is below. I ran the two clips through the amplitudeFrequency FFT with a Saxofony. The first nature clip source consisted of a louder constant noise (more consistent chirping in the background), with different animals and bees. In contrast, the second nature clip contained more punctuated spurts of bird chirps amidst quieter peace.
To assemble the final score, I arranged and mixed the six sections together in Audacity. The original nature clip contained two main "bursts" of bird noise - one in the first third and one at the end. To represent this structure, I created two climaxing moments in the piece - one from 0:20-0:25, and one from 0:47-0:52. These moments contain the spurts of bird chirps from the second nature recording, which I overlapped with various rhythms and intensities of other clips for dramatic effect. I also applied a reverb to the guitar/Stifkarp free recording to give it a more ethereal sound, which gradually crescendo from the middle of the piece into chords during the second climax. I liked playing with various combinations of the different sound clips.
I exported four sound files and combined them in Binaural, and then recorded the output with StereoRecorder for the final output.
