SDIF
SDIF, "Sound Description Interchange Format" is a standard for the well-defined and extensible interchange of a variety of sound descriptions. SDIF consists of a fixed framework plus a large and extensible collection of spectral description types, including time-domain (analogous to regular audio file formats), Sinusoidal Models, other spectral models, and higher-level models. SDIF was jointly developed by IRCAM and CNMAT The University of California, Berkeley (UC Berkeley, Berkeley, Cal, or California) is a public land-grant research university in Berkeley, California.

IRCAM
IRCAM (French: ''Ircam, '', English: Institute for Research and Coordination in Acoustics/Music) is a French institute dedicated to the research of music and sound, especially in the fields of avant garde and electro-acoustical art music. It is situated next to, and is organisationally linked with, the Centre Pompidou in Paris. The extension of the building was designed by Renzo Piano and Richard Rogers. Much of the institute is located underground, beneath the fountain to the east of the buildings. A centre for musical research Several concepts for electronic music and audio processing have emerged at IRCAM. John Chowning pioneered work on FM synthesis at IRCAM, and Miller Puckette originally wrote Max at IRCAM in the mid-1980s, which would become the real-time audio processing graphical programming environment Max/MSP. Max/MSP has subsequently become a widely used tool in electroacoustic music. Many of the techniques associated with spectralism, such as analyses based on ...

Audio File
An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is usually embedded in a container format or an audio data format with defined storage layer. Format types It is important to distinguish between the audio coding format, the container containing the raw audio data, and an audio codec. A codec performs the encoding and decoding of the raw audio data while this encoded data is (usually) stored in a container file. Although most audio file formats support only one type of audio coding data (created with an audio coder), a multimedia container format (as Matroska or AVI) may support multiple types of audio and video data. There are three major groups of audio file formats: * Uncompressed audio f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Additive Synthesis
Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. The timbre of musical instruments can be considered in the light of Fourier series, Fourier theory to consist of multiple harmonic or inharmonic ''Harmonic series (music)#Partial, partials'' or overtones. Each partial is a sine wave of different frequency and amplitude that swells and decays over time due to modulation from an ADSR envelope or low frequency oscillator. Additive synthesis most directly generates sound by adding the output of multiple sine wave generators. Alternative implementations may use pre-computed Wavetable synthesis, wavetables or the inverse fast Fourier transform. Explanation The sounds that are heard in everyday life are not characterized by a single frequency. Instead, they consist of a sum of pure sine frequencies, each one at a different amplitude. When humans hear these frequencies simultaneously, we can recognize the sound. This is true for both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CNMAT
The University of California, Berkeley (UC Berkeley, Berkeley, Cal, or California) is a public land-grant research university in Berkeley, California. Established in 1868 as the University of California, it is the state's first land-grant university and the founding campus of the University of California system. Its fourteen colleges and schools offer over 350 degree programs and enroll some 31,800 undergraduate and 13,200 graduate students. Berkeley ranks among the world's top universities. A founding member of the Association of American Universities, Berkeley hosts many leading research institutes dedicated to science, engineering, and mathematics. The university founded and maintains close relationships with three national laboratories at Berkeley, Livermore and Los Alamos, and has played a prominent role in many scientific advances, from the Manhattan Project and the discovery of 16 chemical elements to breakthroughs in computer science and genomics. Berkeley is also kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
