Musicdisk
Module file (MOD music, tracker music) is a family of music file formats originating from the MOD file format on Amiga systems used in the late 1980s. Those who produce these files (using the software called music trackers) and listen to them form the worldwide MOD scene, a part of the demoscene subculture. The mass interchange of "MOD music" or "tracker music" (music stored in module files created with trackers) evolved from early FIDO networks. Many websites host large numbers of these files, the most comprehensive of them being the Mod Archive. Nowadays, most module files, including ones in compressed form, are supported by most popular media players such as VLC, Foobar2000, Exaile and many others (mainly due to inclusion of common playback libraries such as libmodplug for gstreamer). Structure Module files store digitally recorded samples and several "patterns" or "pages" of music data in a form similar to that of a spreadsheet. These patterns contain note numb ...

File Format
A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary or free. Some file formats are designed for very particular types of data: PNG files, for example, store bitmapped images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container for different types of multimedia including any combination of audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various character encoding schemes. Some file formats, such as HTML, scalable vector graphics, and the source code of computer software are text files with defined syntaxes that allow them to be used for specific purposes.

Commodore Amiga
Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- or 32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. This includes the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS. The Amiga 1000 was released in July 1985, but production problems kept it from becoming widely available until early 1986. The best-selling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The Amiga 3000 was introduced in 1990, followed by the Amiga 500 Plus, and Amiga 600 in March 1992. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha YM3812
The OPL (FM Operator Type-L) series are a family of Sound chip, sound chips developed by Yamaha Corporation, Yamaha. The OPL series are low-cost sound chips providing frequency modulation synthesis, FM synthesis for use in computing, music and video game applications. Internal operation The internal operation of the chips is completely digital. Each FM-tone is generated by a digital oscillator using a form of direct digital synthesis. A low-frequency oscillator and an envelope generator drive an FM operator to produce floating-point output for the DAC. Decapsulation of the chips shows two look-up tables, one for calculating exponents and one for log-sine. This allows the FM operator to calculate its output without any multipliers, using the formula \exp [\log \sin[\varphi_2 + \exp [\log \sin [\varphi_1] + A_1 + A_2] and two 256-entry look-up tables. Both tables are stored as pairs of values rounded to the nearest whole number, with the second value represented as the difference b ...

C (musical Note)
C or Do is the first note and semitone of the C major scale, the third note of the A minor scale (the relative minor of C major), and the fourth note (G, A, B, C) of the Guidonian hand, commonly pitched around 261.63 Hz. The actual frequency has depended on historical pitch standards, and for transposing instruments a distinction is made between written and sounding or concert pitch. It has enharmonic equivalents of B and D. In English the term ''Do'' is used interchangeably with C only by adherents of fixed Do solfège; in the movable Do system Do refers to the tonic of the prevailing key. Frequency Historically, concert pitch has varied. For an instrument in equal temperament tuned to the A440 pitch standard widely adopted in 1939, middle C has a frequency around 261.63 Hz (for other notes see piano key frequencies). Scientific pitch was originally proposed in 1713 by French physicist Joseph Sauveur and based on the numerically convenient frequency of 256 ...

S3M (file Format)
''S3M'' (Scream Tracker 3 Module) is a module file format, the successor to the STM format used by the original Scream Tracker. Both formats are based on the original MOD format used on the Amiga computer. The S3M format has many differences compared to its predecessors. * The format is a hybrid of digital playback and synthesized instruments. The official format specification document covers space for 16 digital channels and 14 synthesized ones with two unused slots out of a total of 32. * Separate volume channel in pattern data. * Supports more instruments than MOD or STM (99 instead of 31). * Default panning of channels can be specified by the composer. * Extra-fine pitch slides are added * Instruments are not limited to a fixed sample rate for a given note. The format stores the instrument's sample rate at middle C. The period table used by S3M is smaller than the one used by the MOD format (only 12 entries, compared to between 36 and 60 for the MOD variations) and uses larger ...

Scream Tracker 3
''Scream Tracker'' is a tracker (an integrated multi-track step sequencer and sampler as a software application). It was created by Psi (Sami Tammilehto), one of the founders of the Finnish demogroup Future Crew. It was written in C and assembly language. The first version (1.0) had monophonic 4-bit output via the PC speaker, as well as 8-bit output via a digital-to-analog converter on the parallel port or a Sound Blaster 1.x card. The first popular version of Scream Tracker, version 2.2, was published in 1990. Versions prior to 3.0 created STM (Scream Tracker Module) files, while versions 3.0 and above used the S3M (ScreamTracker 3 Module) format. The last version of Scream Tracker was 3.21, released in 1994. It was the precursor of the PC tracking scene and its interface inspired newer trackers like Impulse Tracker. As of version 3.0, ''Scream Tracker'' supports up to 99 8-bit samples, 32 channels, 100 patterns, and 256 order positions. It can also handle up to 9 FM-synthesi ...

Kickstart (Amiga)
Kickstart is the bootstrap firmware of the Amiga computers developed by Commodore International. Its purpose is to initialize the Amiga hardware and core components of AmigaOS and then attempt to boot from a bootable volume, such as a floppy disk. Most Amiga models were shipped with the Kickstart firmware stored on ROM chips. Versions Commodore's AmigaOS was formed of both the Kickstart firmware and a software component provided on disk (with the software portion often termed as Workbench). For most AmigaOS updates the Kickstart version number was matched to the Workbench version number. Confusingly, Commodore also used internal revision numbers for Kickstart chips. For example, there were several Kickstart revisions designated as version 2.0. Version summary The first Amiga model, the A1000, required that Kickstart 1.x be loaded from floppy disk into a 256 KB section of RAM called the writable control store (WCS). Some A1000 software titles (notably ''Dragon's L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiptune
Chiptune, also known as chip music or 8-bit music, is a style of synthesized electronic music made using the programmable sound generator (PSG) sound chips or synthesizers in vintage arcade machines, computers and video game consoles. The term is commonly used to refer to tracker format music which intentionally sounds similar to older PSG-created music (this is the original meaning of the term), as well as music that combines PSG sounds with modern musical styles. It has been described as "an interpretation of many genres" since any existing song can be arranged in a chiptune style defined more by choice of instrument and timbre than specific style elements. Technology A waveform generator is a fundamental module in a sound synthesis system. A waveform generator usually produces a basic geometrical waveform with a fixed or variable timbre and variable pitch. Common waveform generator configurations usually included two or three simple waveforms and often a single pseudo- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound On Sound
''Sound on Sound'' is an independently owned monthly music technology magazine published by SOS Publications Group, based in Cambridge, United Kingdom.

OctaMED
OctaMED is a popular music tracker for the Commodore Amiga, written by Teijo Kinnunen. The first version, 1.12, was released in 1989 under the name MED, which stands for Music EDitor. In April 1990, version 2.00 was released with MIDI support as the main improvement. In 1991 the first version with the name OctaMED was released, so-called as it could replay eight independent channels on the Amiga's four-channel sound chip. This was also the first commercial version of the software. The publisher throughout has been RBF Software of Southampton, UK which is run by Ray Burt-Frost. History The distinguishing feature of MED and OctaMED in comparison to other music trackers on the Amiga was that MED and OctaMED had native MIDI support for external instruments via the Amiga's serial port – this allowed many musicians to sequence a combination of outboard studio equipment and internally generated sounds to create studio quality releases such as "I Created Disco" by Calvin Harris. OctaM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panning (audio)
Panning is the distribution of an audio signal (either monaural or stereophonic pairs) into a new stereo or multi-channel sound field determined by a pan control setting. A typical physical recording console has a pan control for each incoming source channel. A pan control or pan pot (short for "panning potentiometer") is an analog control with a position indicator which can range continuously from the 7 o'clock when fully left to the 5 o'clock position fully right. Audio mixing software replaces pan pots with on-screen virtual knobs or sliders which function like their physical counterparts. Overview A pan pot has an internal architecture which determines how much of a source signal is sent to the left and right buses. "Pan pots split audio signals into left and right channels, each equipped with its own discrete gain (volume) control."Hodgson, Jay (2010). ''Understanding Records'', p.162. . This signal distribution is often called a taper or law. When centered (at 12 o'clock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
