Demo patchers from yesterday’s lecture are in iLocker. Look for patchers MSPBasic1[a - e].maxpat.

Outline of topics covered:

• Digital Audio basics relating to how computers generate audio samples (in blocks, or vectors). The larger the vector sample size, the less strain on the computer, more latency.
• Audio Rate and Control Rate, pertaining to patch cord connections and the rate at which they are computed.
• ~ denotes audio objects (tilde looks like a sine wave)
• dac~ and EZdac~ (and their related messages: start, startwindow, and stop)
• basic objects: cycle~, *~ (gain).
• The reliance on floating point numbers for messages, rather than integers
• audio discontinuity leading to clicks requires use of line~ for smoothing message changes, especially for amplitude
• replacing the sine wave table used for cycle~ with an audio signal of your choice (as long as it is 512 samples).
