This document presents all materials related to the topic of
AUDIO on the Toolbox:
DATA:
DOCUMENTS:
SOURCE:
- CDio, software for Writing and Reading CDs enables one to make an SGI efs OR ISO or Audio CD
- public:
- Chaos: The Chaotic Music Generator, Version 1.0
- rsynth: Rsynth speech synthesizer ported to SGI, Version 1.0
- public/freeware1.0:
- Cspect -- real-time oscilloscope/spectrum analyzer
- mpegaudio -- mpeg encoder/decoder does LayerI&II audio
- sono -- generate a score from electroacoustic piece
- sox10, v1.0-ircam -- universal sound converter
- tracker, v4.31 -- modfile-player
- src/demos/audio contains,
- amesh and ameshC, provide C++ and "straight C" versions of an "audio mesh" spectrum analysis of an incoming audio signal and displays it in a real-time "waterfall" of frequency spectrums.
- synthia, a midi synthesizer, plays a midi sound file and simultaneously displays the notes on a simulated keyboard.
- video, contains video demo progs including:
- specialfx, demos many of the special effects features possible with Galileo, Indigo2 Video and IndyVideo, particularly in the areas of chroma keying, luma keying, and transitions (also known as wipes & fades, blends, and/or switches),
- vidpaint, captures video into memory at the 1/4 by 1/4 size (1/8 the area of the full size of the source you are using), and then draws the frames into a window,
- vidtmesh, captures video into memory at the 1/4 by 1/4 size, (1/8 the area of the full size of the source you are using) and places the frames onto a 3D triangle mesh (tmesh) grid, which you can then manipulate in space,
- bigvideoin, simple mini app shows a zoomed up videoin window nearly filling your display with video, and,
- trails, a specialty program, sets up a feedback loop so that you can see trailing effects.
- src/exampleCode/audio contains,
- DAT: 3 DAT example programs,
- ascope: displays left channel of data coming in from an audio port,
- harmonizer: real-time audio pitch bender example,
- midi: example programs using libmidi.a illustrate basic use of the MIDI library,
- reverb: simulated reverberation for real-time audio input and output<
- rock: the indigo memorial barbeque theme song rapp, a study in random looping of musical "melodies" and rhythms,
- somePlayback: code to generate a bunch of oscillators, waveforms, change playback rate, mix, change pitch, loop audio samples and send them to the speaker,
- sonic: simple real time audio spatialization example with graphics, and,
- tablenet: generates small series of waveforms and writes them into a 16-bit AIFF file.
- src/exampleCode/inventor/soundspheres: Open Inventor-version of a very primitive spacial audio program
- src/exampleCode/inventor/ivcalc: full function infix scientific calculator includes sound cues
- src/exampleCode/irix/playEngine: routines permit playing audio track without interference from OS multitasking activities.
- sgi src/exampleCode/speech speech recognition examples, IRIX 5.3 inst images, and utilities.
