WildMIDI
WildMIDI is a free open-source software synthesizer which converts MIDI note data into an audio signal using GUS sound patches without need for a GUS patch-compatible soundcard. WildMIDI, whose aim is to be as small as possible and easily portable, started in December 2001, can act as a virtual MIDI device, capable of receiving MIDI data from any program and transforming it into audio on-the-fly. It is the standard MIDI renderer for the GStreamer framework. Features WildMIDI consists of two parts, the library which other applications can link against and a command-line (CLI) player used to show off the features of the library itself.

Standard MIDI Files
MIDI (; Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper ''Universal Synthesizer Interface'' published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City. A single MIDI cable can carry up to sixteen channels of MIDI data, each of which can be routed to a separate device. Each interaction with a key, button, knob or slider is converted into a MIDI event, which specifies musical instructions, such as a note's pitch, timing and loudness. One common MIDI application is to play a MIDI keyboard or other controller and use it to trigger a digital sound module (which contains synthesized musical sounds) to generate sounds, which the ...

Music Player Daemon
Music Player Daemon (MPD) is a free and open music player server. It plays audio files, organizes playlists and maintains a music database. In order to interact with it, a client program is needed. The MPD distribution includes mpc, a simple command line client. MPD is used in proprietary audio hardware. The MPD project maintains a list of vendors, some of which infringe the GPL. Design MPD simply runs in the background playing music from its playlist. Client programs communicate with MPD to manipulate playback, the playlist, and the database. It is not a full-featured music player program such as Amarok, but its clients can serve such role. MPD uses a flat file database to maintain the basic music file information when it is not running. Once the daemon has been started, the database is kept completely in-memory and no hard disk access is necessary to look up or search for local audio files. Generally, music files must be located in a sub-directory of the music directory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Qmmp
qmmp (for ''Qt-based MultiMedia Player'') is a free and open-source cross-platform audio player that is similar to Winamp. It is written in C++ using the Qt widget toolkit for the user interface. It officially supports the operating systems Linux, FreeBSD and Microsoft Windows. In most popular Linux distributions, it is available through the standard package repositories. Until Audacious switched to Qt in version 4.0, QMMP was the only audio player to use Qt and not feature a database. Features qmmp is known for its small, themeable user interface and low use of system resources. The user interface and behaviour is very similar to the at its time very popular Winamp. By supporting Winamp (Classic) skin files it can easily be configured to look exactly the same as Winamp 2.x. It is also catering for more discerning or audiophile listeners with support for cue sheets and volume normalization according to the ReplayGain standard. Album cover art is supported using separate side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fork (software Development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community; as such, it is a form of schism. Grounds for forking are varying user preferences and stagnated or discontinued development of the original software. Free and open-source software is that which, by definition, may be forked from the original development team without prior permission, and without violating copyright law. However, licensed forks of proprietary software (''e.g.'' Unix) also happen. Etymology The word "fork" has been used to mean "to divide in branches, go separate ways" as early as the 14th century. In the software environment, the word evokes the fork system call, which causes a running process to split itself into two (almost) identical copies that (ty ...

Sound Blaster
Sound Blaster is a family of sound cards designed by Singaporean technology company Creative Technology (known in the US as Creative Labs). Sound Blaster sound cards were the de facto standard for consumer audio on the IBM PC compatible system platform, until the widespread transition to ''Microsoft'' Windows 95, which standardized the programming interface at application level (eliminating the importance of backward compatibility with Sound Blaster), and the evolution in PC design led to onboard audio electronics, which commoditized PC audio functionality. By 1995, Sound Blaster cards had sold over 15 million units worldwide and accounted for seven out of ten sound card sales. Creative Music System and Game Blaster Creative Music System The history of Creative sound cards started with the release of the Creative Music System ("C/MS") CT-1300 board in August 1987. It contained two Philips SAA1099 integrated circuits, which, together, provided 12 channels of square-wave "bee-i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenAL
OpenAL (Open Audio Library) is a cross-platform audio application programming interface (API). It is designed for efficient rendering of multichannel three-dimensional positional audio. Its API style and conventions deliberately resemble those of OpenGL. OpenAL is an environmental 3D audio library, which can add realism to a game by simulating attenuation (degradation of sound over distance), the Doppler effect (change in frequency as a result of motion), and material densities. OpenAL aimed to originally be an open standard and open-source replacement for proprietary (and generally incompatible with one another) 3D audio APIs such as DirectSound and Core Audio, though in practice has largely been implemented on various platforms as a wrapper around said proprietary APIs or as a proprietary and vendor-specific fork. While the reference implementation later became proprietary, there are open source implementations such as OpenAL Soft available. History OpenAL was originally ...

WinMM
This article describes audio APIs and components in Microsoft Windows which are now obsolete or deprecated. Multimedia Extensions (MME) The MME API or the Windows Multimedia API (also known as ''WinMM'') was the first universal and standardized Windows audio API. Wave sound events played in Windows (up to Windows XP) and MIDI I/O use MME. The devices listed in the ''Multimedia/Sounds and Audio'' control panel applet represent the MME API of the sound card driver. The Multimedia Extensions ( interfaces) were released in autumn 1991 to support sound cards, as well as CD-ROM drives, which were then becoming increasingly available. The Multimedia Extensions were released to Original Equipment Manufacturers (OEMs), mainly CD-ROM drive and sound card manufacturers, and added basic multimedia support for audio input and output and a CD audio player application to Windows 3.0. The Multimedia Extensions' new features were not available in Windows 3.0 real mode, only in standard and 386 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Linux Sound Architecture
Advanced Linux Sound Architecture (ALSA) is a software framework and part of the Linux kernel that provides an application programming interface (API) for sound card device drivers. Some of the goals of the ALSA project at its inception were automatic configuration of sound-card hardware and graceful handling of multiple sound devices in a system. ALSA is released under GNU General Public License, GPL-2.0-or-later and GNU Lesser General Public License, LGPL-2.1-or-later. On Linux, sound servers, like sndio, PulseAudio, JACK Audio Connection Kit, JACK (low-latency professional-grade audio editing and mixing) and PipeWire, and higher-level APIs (e.g OpenAL, Simple DirectMedia Layer#Subsystems, SDL audio, etc.) work on top of ALSA and its sound card device drivers. ALSA succeeded the older Linux port of the Open Sound System (OSS). History The project to develop ALSA was led by Jaroslav Kysela, and was based on the Linux device driver for the Gravis Ultrasound sound card. It sta ...

Open Sound System
The Open Sound System (OSS) is an interface for making and capturing sound in Unix and Unix-like operating systems. It is based on standard Unix devices system calls (i.e. POSIX read, write, ioctl, etc.). The term also sometimes refers to the software in a Unix kernel that provides the OSS interface; it can be thought of as a device driver (or a collection of device drivers) for sound controller hardware. The goal of OSS is to allow the writing of sound-based applications that are agnostic of the underlying sound hardware. OSS was created by Hannu Savolainen and is distributed under four license options, three of which are free software licences, thus making OSS free software. API The API is designed to use the traditional Unix framework of open(), read(), write(), and ioctl(), via special devices. For instance, the default device for sound input and output is /dev/dsp. Examples using the shell: cat /dev/random > /dev/dsp # plays white noise through the speaker cat / ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
