Intro to Audio and Video Synthesis

An Independent Study Course with Matthew Long

August 22

• went over John's Pd tutorial parts I and II

• project: make a cross fader which fades between a phasor and a cosine wave

August 29

• reviewed material from last week
• project: alter phasor~ in crossfader project so phasor~ itself goes from -1 to 1 in amplitude
• finish wiki homepage

• go through Part III of the tutorial

September 5

• went over project to make phasor~ go from -1 to 1

• added objects to create frequency relationship between the two wave generators
• assignments:
  • add more random and metro objects to PDPatch to randomize the frequency relationship between cosine and phasor
  • add slider to change the range of random master frequency
  • what other random and metro objects can you add?
  • where can you add a line or line~ object?
• upload all work to the wiki

September 12

Matt couldn't make class

September 19

• explored/revisited |line~|, |metro|, etc. Introduced |stop(

• assignment: make the scrubber in Part_IV:_Sampled_Sounds_and_Scrubbing

September 25

• Mic recording revisited
• Basic enveloping

• ADSR envelopes ADSR_Directions

October 3

• Find a recording of electronic music
• Listen and write a one-page critical response - the response should not be descriptive. It should be your personal opinion and interpretation of the work.
• ADSR again
• Make something with additive and subtractive synthesis and an ADSR envelope

October 24

• FM synth, attach keyboard to computer and get midi in from Pd

• Assignment:

  • hook up music keyboard to computer and get Pd to recognize it (use 'test audio and midi' in Pd menu)
  • add third operator which manipulates the freq of the modulator.
  • Play with the mathematical relationships between the operators to create a new and unique sound
  • record the sound in Pd
  • upload the resulting sound and the Pd patch that created it by midnight Tues/Wed

October 31

• startup flags on Pd

  • -midiindev <number>

• making an audio file in Pd
• saving your settings
• radio box
• experimenting with fm
• table and saving presets

• Assignment:

  • come up with more presents
  • read about wavetable synthesis and see if you can come up with a simple example

November 7

• Wave table values (0-1)
• Polyphonic midi
• Multiple wave table synthesis
• Vector Synthesis

• Assignment:

  • Build a wave stacking patch
  • Experiment with a vector patch
  • Read 159-163 in CMT

• Steve's PolySynth.zip Polyphonic Synth

November 20

conversation only --- brainstorming about the course

• more manipulation using real-world sounds live and recorded
• meet 2x/week for 30 minutes each time?
• integrate Pd with Acid Xpress?
• explore patterns, loops, sequencing in Pd

  • install Midi-Yoke

• start collecting sounds you think are interesting in Pd and
  • figure out what need to trigger the sound
  • save some interesting Pd sounds as wave files?

• check out buzz for fun

• check out cecilia for fun

• final project will be 3-5 piece which can be loop-based, using Acid/Sony music studio triggering sounds in Pd as well as using built-in sounds
• install Audacity (beta version) and optional downloads (LADSPA, VST, LAME, Plugins)
