Sound cards have evolved in terms of digital audio sampling rate (starting from 8-bit 11025 Hz, to 32-bit, 192 kHz that the latest solutions support). Along the way, some cards started offering wavetable synthesis , which provides superior MIDI synthesis quality relative to the earlier Yamaha OPL based solutions, which uses FM-synthesis .
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.
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave.In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal.
Sound Blaster AWE32 (CT3990) The Sound Blaster AWE32 is an ISA sound card from Creative Technology. It is an expansion board for PCs and is part of the Sound Blaster family of products. The Sound Blaster AWE32, introduced in March 1994, was a near full-length ISA sound card, measuring 14 inches (356 mm) in length, due to the number of features ...
Of critical importance at the time was support of the Creative Labs Sound Blaster, a card that was the ubiquitous sound standard of the day. Soundscape can emulate the Sound Blaster 2.0, an 8-bit monaural device with FM synthesis capability. While the digital sound emulation was quite good, the FM synthesis emulation leaves much to be desired.
The Windows operating system's 16-bit subsystem is lacking in several areas which directly or indirectly affect VDMSound emulation: Incomplete DPMI support in Windows NT/2000/XP results in a number of games not starting or crashing randomly when they communicate with the emulated sound card
There were also such exotic cards as Sound Blaster PCI 512 which were delivered to Compaq and Dell. The Platinum, X-Gamer, MP3+ and Player were all non-5.1 cards and only supported 4.0 (stereo with rear speaker support). The generation 3 of Sound Blaster Live! cards appeared on the market in autumn of 2000.
AdLib used Yamaha's YM3812 sound chip, which produces sound by FM synthesis. The AdLib card consisted of a YM3812 chip with off-the-shelf external glue logic to plug into a standard PC-compatible ISA 8-bit slot. PC software-generated multitimbral music and sound effects through the AdLib card, although the acoustic quality was distinctly ...
