[spectre] [nfo] GOTO10 workshop at 0KN0 - anASPintro - belgium july 2005

[propaganda at goto10.org]

The ASP Introduction workshop from goto10 and hosted by okno.be intends
to introduce the students to the basics of Audio Signal Processing in
the fields of realtime music production. The workshop is specifically
made for people willing to develop their work in the digital sound field
and for people curious about the processes involved behind audio
software they already use. The workshop will also teach and demonstrate
which free technologies are available for audio and video streaming. The
workshop will end with an open placard event (headphone live festival -
more infos soon).

ASP and Audio Synthesis
 Audio processing is the manipulation, either measurement or filtering,
 of an analog (voltage level) or digital (binary numbers) representation
 of sound. In the Digital Signal Processing field, this implies the
 conversion of the signal from an analog to a digital one and vice versa
 with a focus on one particular domain (time, space, frequency,...).

 Audio Synthesis is the art of producing artificially generated sounds
 using various techniques. This creation can be done either in the
 analog world (current manipulation) or digital world (discrete values
 manipulation).
   
 topics
 1. understanding the physical sound
         1.1 the phenomenon of sound
         1.2 perceived qualities (duration, pitch, loudness) of
	 sound
         1.3 quantitative measurements (time, frequency,
	 amplitude) of such qualities
 2. understanding the digital representation of physical sound
         2.1 basic sampling theory
         2.2 ADC & DAC
         2.3 binary numbers
 3. basic audio signal processing
         3.1 adding signals
         3.2 multiplying signals
 4. synthesis
         4.1 simple FM
         4.2 simple wavetable
         4.3 simple granular
 5. samples/soundfiles
         5.1 different soundfiles
         5.2 loss vs. lossless compression

PURE DATA
 PD (aka Pure Data) is a real-time graphical programming environment for
 audio, video, and graphical processing. It is the third major branch of
 the family of patcher programming languages known as Max (Max/FTS, ISPW
 Max, Max/MSP, jMax, etc.) originally developed by Miller Puckette and
 company at IRCAM. The core of Pd is written and maintained by Miller
 Puckette and includes the work of many developers, making the whole
 package very much a community effort.

 It's hard to describe the possibilities of such an environment as its
 field of creation is almost infinite. From audio processing, to video,
 2D/3D, interactivity, on-line experimentation, streaming and sensors,
 Pure-Data can handle all of these and provide a rock stable system
 which is perfect for performances and installations of any kind.
   
 topics
 1. messages vs. audio signals
    	1.1 how audio signal differs from message signal
    	1.2 how to see audio signals
 2. audio building blocks and operators
	2.1 oscillators
	2.2 [+~], [-~] and others
        2.3 ramping and envelopes
 3. delay & filters
	3.1 introducing delay
        3.2 various types of filters
 4. let's make
        4.1 a FM patch
        4.2 a sample playing patch
        4.3 an effect patch

MFP
 The aim of My First Packet is to provide graphical high-level modules
 dedicated to quickly build an audio/video mixing and streaming platform
 on linux and eventually OSX. MFP works like a high level and friendly
 environment built on top of PD, PDP and PiDiP.
  
 topics
 - what is an abstraction
 - presentation of the different possibilities
 - presentation of Open Sound Control
 - presentation of icecast, ogg, vorbis, and theora
 - building an audio and video streaming system
