Scream Tracker
''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 ...

Future Crew
Future Crew was a Finnish demogroup that created PC demos and software, active mostly between 1987 and 1994. History The group was founded in 1986 by PSI (Sami Tammilehto) and JPM (Jussi Markula) as a Commodore 64 group, before moving to the PC demoscene in 1988; other members included, over time, Trug, Wildfire, Pixel, ICE, GORE, Abyss, Purple Motion, and Skaven, as well as several others. Noteworthy demos by Future Crew include ''Unreal'' (released at Assembly 1992), ''Panic'' (released at The Party 1992) and ''Second Reality'' (released at Assembly 1993). Second Reality may be considered one of the most influential PC demos ever made. Future Crew was also responsible for the popular MOD (file format), MOD editor ''Scream Tracker'', which was fashioned after the Amiga Soundtracker as well as the '' Advanced DigiPlayer'' sound editor, and later became itself inspiration for other trackers like Impulse Tracker. Future Crew was co-organizer of the first Assembly demo party ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio Bit Depth
In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. Examples of bit depth include Compact Disc Digital Audio, which uses 16 bits per sample, and DVD-Audio and Blu-ray Disc which can support up to 24 bits per sample. In basic implementations, variations in bit depth primarily affect the noise level from quantization error—thus the signal-to-noise ratio (SNR) and dynamic range. However, techniques such as dithering, noise shaping, and oversampling can mitigate these effects without changing the bit depth. Bit depth also affects bit rate and file size. Bit depth is only meaningful in reference to a PCM digital signal. Non-PCM formats, such as lossy compression formats, do not have associated bit depths. Binary representation A PCM signal is a sequence of digital audio samples containing the data providing the necessary information to reconstruc ...

Demoscene Software
The demoscene is an international computer art subculture focused on producing demos: self-contained, sometimes extremely small, computer programs that produce audiovisual presentations. The purpose of a demo is to show off programming, visual art, and musical skills. Demos and other demoscene productions (graphics, music, videos, games) are shared at festivals known as demoparties, voted on by those who attend and released online. The scene started with the home computer revolution of the early 1980s, and the subsequent advent of software cracking. Crackers altered the code of video games to remove copy protection, claiming credit by adding introduction screens of their own (" cracktros"). They soon started competing for the best visual presentation of these additions. Through the making of intros and stand-alone demos, a new community eventually evolved, independent of the gaming and software sharing scenes. Demoscene productions can be made with the latest consumer techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MilkyTracker
MilkyTracker is a free software multi-platform music tracker for composing music in the MOD and XM module file formats. It is a clone that attempts to recreate the module replay and user experience of the popular DOS program FastTracker 2, with special playback modes available for improved Amiga ProTracker 2/3 compatibility. Module tracking Module composition or "tracking" is done through the control of multichannel sample playback. An instrument is created by arranging one or more audio samples across a keyboard range. The instrument is then sequenced on a monophonic track that contains note, volume and effect data. A pattern is a series of tracks that are played back simultaneously. A song is then created by arranging the patterns. Features MilkyTracker is able to open several legacy music module formats and is able to save in . xm and .mod formats. Like FastTracker, MilkyTracker contains a sample editor and an instrument editor. The envelope editor of the instrument editor ...

OpenMPT
OpenMPT is an open-source audio module tracker for Windows (with an intended Wine-functionality for UNIX and Linux x86-systems). It was previously called ModPlug Tracker, and was first released by Olivier Lapicque in September 1997. ''Computer Music'' magazine listed OpenMPT among the top five free music trackers in 2007, and it is one of the most widely used trackers. History MOD Plugin and ModPlug Tracker OpenMPT was initially developed as a browser plug-in called MOD Plugin, which enabled users to play music and other sounds encoded in module files. ModPlug Tracker, along with a player application named ModPlug Player, evolved from this plug-in. In December 1999, Olivier Lapicque sent the module-playing parts of ModPlug Tracker's source code to Kenton Varda, under the GPL-2.0-or-later, to write a plugin for XMMS based on the code. In 2001, the source code was released in the public domain, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FastTracker 2
FastTracker 2 (also referred to as FastTracker II) is a music tracker created by Fredrik "Mr. H" Huss and Magnus "Vogue" Högdahl, two members of the demogroup Triton (who later founded Starbreeze Studios) which set about releasing their own tracker after breaking into the scene in 1992 and winning several demo competitions. The source code of FastTracker 2 is written in Pascal using Borland Pascal 7 and TASM. The program works natively under MS-DOS. History In 1993, Triton released FastTracker. This tracker was able to load and save standard four channel MOD files, as well as extended MOD files with six or eight channels (identical to standard MOD files, aside from the extra channel data and ID markers "6CHN" or "8CHN"). It was only compatible with Creative Labs' SoundBlaster series of sound cards, which were most popular on the PC at that time. The whole editor was a single 43 KiB DOS executable. Through 1994, the musicians in Triton released some songs in a new multi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha YMF278
The Yamaha YMF278B, also known as the OPL4 (OPL is an acronym for ''FM Operator Type-L''), is a sound chip that incorporates both FM synthesis and sample-based synthesis (often incorrectly called "wavetable synthesis") by Yamaha. Sample-based synthesis component The sample synthesis part is based on pulse-code modulation (PCM). It features: * Up to 24 simultaneous sounds (voices) * Output sampling frequency of 44.1 kHz (it can also accept 22.05-kHz samples – they are up-sampled to 44.1 kHz before output) * Waveform data lengths of 8, 12, or 16 bits * Stereo output (with a 4-bit/16-level pan for each voice) The PCM synthesizer part accepts: * Up to 4 MB of external memory for wave data * Up to 512 samples * External ROM or SRAM memory. If SRAM is connected, then wave data can be downloaded from the OPL4. * Chip select signals for 128 KB, 512 KB, 1 MB, or 2 MB memory can be output.

Yamaha YMF262
The OPL (FM Operator Type-L) series are a family of sound chips developed by Yamaha. The OPL series are low-cost sound chips providing 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">varphi_2_+_\exp_[\log_\sin_[\varphi_1.html" ;"title="log \sin[\varphi_2 + \exp [\log \sin [\varphi_1">log \sin[\varphi_2 + \exp [\log \sin [\varphi_1+ A_1 + A_2] and two 256-entry look-up tables.
