DSP – according to the Arctic Monkeys…

The time domain:

The frequency domain:

Samples, impulses, and convolution

(in the time domain)

  • Decomposition
  • Unit impulse (delta function)
  • convolution (from the input side and output side)
  • filters
Reference: http://www.dspguide.com “The Scientist and Engineer’s Guide to DSP”, By Steven Smith – chapters 6-7

Clocks

Time, under a microscope.

Granular synthesis

Audio under a microscope.

Andy Farnell, “Designing Sound” http://aspress.co.uk/sd/index.php

Chapter 16.7 Methods “Granular” p. 257

Chapter 13 “Shaping Sound” p. 205

Destroying information

Abstract is what remains after shedding details.

Example Max patches:

  • timestrech3.maxpat
  • nothingness.maxpat

Assignment:

See notes from last week. https://reactivemusic.net/?p=10059

Work through the convolution examples on your own. Its important to have a physical concept of signals, in various transformations. Become a wave. Have an out of body experience. Take a good look at yourself.

ep-4yy13 DSP – week 5

transforming music into music

Examples

Notes

  • Solving problems
  • Exploration
  • Stories

Assignments

Mystery field recording: (email to me this week)

  • Record a very short sound clip (less than 15 seconds)
  • It should be something that you hear, not something you produce – for example, a fire-truck, a refrigerator, the wind…
  • Please don’t tell me where the sound came from. We will try to guess. When you send the file, just have your name on it. For example: field-recoding-keithMoon.mp3
  • Alternative: Record an impulse response in an interesting space. We will try to guess the space. The impulse can be anything, for example: hand clap, yelling “hello”, a trumpet.
  • Extra credit – transcribe your recorded event. For example, what chord or rhythms do the machines in a coffee shop produce?
  • Email a link or attachment to: [email protected]

Composition: Sound-byte (due March 17th)

  • The sound-byte is a short audio clip of speech.
  • The speech can come from anywhere. Something familiar, something famous, something unusual.
  • Every sound in the composition is derived only from the sound-byte. You can use any tool or method.
  • The sound-byte in its original form should occur somewhere in the piece
  • Duration: roughly 2-3 minutes?  That is up to you.

Music from the future:

Please send me a link to your future music piece – sometime before the end of the semester
