![]() ![]() On the Macintosh, you can use the built-in internal or external sound system or dedicated sound hardware such as a Digidesign AudioMedia, SoundTools or ProTools system or a MediaVision ProAudioSpectrum card. The computer must have sound output capability. See the Internet guide at the end of the report for more information on obtaining the program. ![]() Versions of Csound are available via anonymous FTP on the Internet for most types of computers. You will need a computer on which Csound can run. As computer systems get faster, Csound will increasingly be used for real-time synthesis.Ĭomputer hardware and software requirements for using Csound This is why it is usually used for non-real-time synthesis. Because Csound runs on general purpose computers rather than dedicated hardware found in commercial synthesis, it cannot run as fast. The trade-off for Csound’s versatility is speed. In addition, Csound includes many functions which are not available in synthesizers, such as physical modeling, phase vocoding, linear predictive coding and spectral analysis and resynthesis. If you require an instrument with a complex arrangement of 1000 oscillators, you can create it in Csound. The blocks can be arranged in any order and in any quantity. These are similar to the building blocks found in analog and digital synthesizers.Ĭsound has several advantages over hardware synthesizers, however. The instruments in the orchestra file are created from a set of building blocks which include oscillators, envelope generators, function generators, sample file input, physical models, filters, effects and more. On fast computers, Csound can process live MIDI input and play sound in real-time. A standard MIDI file from a sequencer can be converted to a Csound score file, or Csound can process a standard MIDI file while running using MIDI information to play the orchestra instruments directly. In other words, the orchestra and score files specify synthesis computations to be performed, and Csound generates samples by performing these computations directly.Ĭsound can also accept MIDI input in two ways. Csound reads these files as input and produces digital audio samples, which are then written to disk as a sound file. The score file is a list of the notes and control parameters which play the instruments. The orchestra file contains the specifications for the software "instruments" to be played. ![]() When using Csound, the first step is to create two text files: an orchestra and a score file. Since Csound is currently used mostly for non-real-time synthesis, the descriptions in the report pertain to using Csound in this mode, unless otherwise noted. However, most of the information contained in this report is applicable to other versions. This paper describes the use of Csound on a Macintosh computer. Currently, versions of the program are available for Macintosh, PowerMac, IBM-PC, Atari, Amiga, NeXT, Sun, SGI, HP and other computers. That is, Csound can play sound out of the computer as the program is running.Ĭsound runs on a variety of computer platforms. On a fast computer system, Csound may be able to perform synthesis in real-time, dependent on the complexity of the input files. The time it takes to process is dependent on the speed of the computer, the complexity of the instruments and the length of the score. When used in this mode, Csound computes sound output and writes it to a file, which can then be played back. This means that sound does not come out immediately upon running the program. "Csound" refers to both a software synthesis language and a program for translating this language into sound.Ĭsound is generally used for non-real-time synthesis. This process is commonly referred to as software synthesis. Csound is a public domain computer program which processes text files to synthesize audio and music on a computer. ![]()
