Sound Blaster 16
The Sound Blaster 16 is a series of sound cards by Creative Technology, first released in June 1992 for IBM PC compatible, PCs with an Industry Standard Architecture, ISA or conventional PCI, PCI slot. It was the successor to the Sound Blaster Pro series of sound cards and introduced Compact Disc, CD-quality digital audio to the Sound Blaster line. For optional wavetable synthesis, the ''Sound Blaster 16'' also added an expansion-header for add-on MIDI-daughterboards, called a Creative Wave Blaster, Wave Blaster connector, and a game port for optional connection with external MIDI sound modules. The ''Sound Blaster 16'' retained the Pro's OPL-3 support for FM synthesis, and was mostly compatible with software written for the older Sound Blaster and Sound Blaster Pro sound cards. The SB16's MPU-401 emulation was limited to UART (dumb) mode only, but it was sufficient for most MIDI software. When a daughterboard, such as the Creative Wave Blaster, Wave Blaster, Roland Sound Canva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

UART
A universal asynchronous receiver-transmitter (UART ) is a peripheral device for asynchronous serial communication in which the data format and transmission speeds are configurable. It sends data bits one by one, from the least significant to the most significant, framed by start and stop bits so that precise timing is handled by the communication channel. The electric signaling levels are handled by a driver circuit external to the UART. Common signal levels are RS-232, RS-485, and raw TTL for short debugging links. Early teletypewriters used current loops. It was one of the earliest computer communication devices, used to attach teletypewriters for an operator console. It was also an early hardware system for the Internet. A UART is usually implemented in an integrated circuit (IC) and used for serial communications over a computer or peripheral device serial port. One or more UART peripherals are commonly integrated in microcontroller chips. Specialised UARTs are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulse-code Modulation
Pulse-code modulation (PCM) is a method used to digitally represent analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. Alec Reeves, Claude Shannon, Barney Oliver and John R. Pierce are credited with its invention. Linear pulse-code modulation (LPCM) is a specific type of PCM in which the quantization levels are linearly uniform. This is in contrast to PCM encodings in which quantization levels vary as a function of amplitude (as with the A-law algorithm or the μ-law algorithm). Though ''PCM'' is a more general term, it is often used to describe data encoded as LPCM. A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the sampling rate, which is the number of ...

3D Audio Effect
3D audio effects are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones. This frequently involves the virtual placement of sound sources anywhere in three-dimensional space, including behind, above or below the listener. 3-D audio (processing) is the spatial domain convolution of sound waves using head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3-D space. It allows trickery of the brain using the ears and auditory nerves, pretending to place different sounds in different 3-D locations upon hearing the sounds, even though the sounds may just be produced from only two speakers (dissimilar to surround sound). Complete 3D positional audio Using head-related transfer functions and reverberation, the changes of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QSound
QSound is the original name for a positional three-dimensional (3D) sound processing algorithm made by QSound Labs that creates 3D audio effects from multiple monophonic sources and sums the outputs to two channels for presentation over regular stereo speakers. QSound was eventually re-dubbed "Q1" after the introduction of "Q2", a positional 3D algorithm for headphones. When multi-speaker surround system support was later added to the positional 3D process, the QSound positional 3D audio process became known simply as "Q3D". Technology QSound is essentially a filtering algorithm. It manipulates timing, amplitude, and frequency response to produce a binaural image. Systems like QSound rely on the fact that a sound arriving from one side of the listener will reach one ear before the other and that when it reaches the furthest ear, it is lower in amplitude and spectrally altered due to obstruction by the head. However, the ideal algorithm was arrived at empirically, with paramet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bochs
Bochs (pronounced "box") is a portable IA-32 and x86-64 IBM PC compatible emulator and debugger mostly written in C++ and distributed as free software under the GNU Lesser General Public License. It supports emulation of the processor(s) (including protected mode), memory, disks, display, Ethernet, BIOS and common hardware peripherals of PCs. Many guest operating systems can be run using the emulator including DOS, several versions of Linux, Xenix, Microsoft Windows, BSDs and Rhapsody OS ( precursor of Mac OS X Public Beta). Bochs runs on many host operating systems, including Android OS, Linux, macOS, PlayStation 2, Windows, and Windows CE along with its derivatives. Bochs is mostly used for operating system development (when an emulated operating system crashes, it does not crash the host operating system, so the emulated OS can be debugged) and to run other guest operating systems inside already running host operating systems. It can also be used to run older software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QEMU
The Quick Emulator (QEMU) is a free and open-source emulator that uses dynamic binary translation to emulate a computer's processor; that is, it translates the emulated binary codes to an equivalent binary format which is executed by the machine.

DOSBox
DOSBox is a free and open-source MS-DOS emulator. It supports running programs primarily video games that are otherwise inaccessible since hardware for running a compatible disk operating system (DOS) is obsolete and generally unavailable today. It was first released in 2002, when DOS technology was becoming obsolete. Its adoption for running DOS games is relatively widespread; partially driven by its use in commercial re-releases of games. Development Before Windows XP, consumer-oriented versions of Windows were based on MS-DOS. Windows 3.0 and its updates were operating environments that ran on top of MS-DOS, and the Windows 9x series consisted of operating systems that were still based on MS-DOS. These versions of Windows could run DOS applications. Conversely, the Windows NT operating systems were not based on DOS. A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Althou ...
