The sole DSP-like feature of the circuit was ADPCM decompression. FM radio quality) and record at up to 12 kHz (approx. It could play back monaural sampled sound at up to 23 kHz sampling frequency (approx. This actually stood for Digital SOUND Processor, rather than the more common digital signal processor, and was really a simple micro-controller from the Intel MCS-51 family (supplied by Intel and Matra MHS, among others). Creative used the 'DSP' acronym to designate the digital audio part of the Sound Blaster. It provided perfect compatibility with the then market leader AdLib sound card, which had gained support in PC games in the preceding years. In addition to Game Blaster features, it had an 11-voice FM synthesizer using the Yamaha YM3812 chip, also known as OPL2. The first board bearing the Sound Blaster name appeared in 1989. First Sound Blasters: the right bundle Sound Blaster 1.0 Creative did not change any of the labeling or program names on the disks that came with the Game Blaster, but also included a later revision of the game Silpheed that added support for the C/MS hardware. This card was identical in every way to the precursor C/MS hardware. Game BlasterĪ year later, in 1988, Creative marketed the C/MS via Radio Shack under the name Game Blaster. Surprisingly, the board also contained a large 40-pin PGA (Creative Technology Programmable Logic) integrated circuit, bearing a CT 1302A CTPL 8708 serigraphed inscription and looking exactly like the DSP of the later Sound Blaster. On the C/MS board in particular, the Philips chips had white pieces of paper with a fantasy CMS-301 inscription on them real Creative parts usually had consistent CT number references. The various integrated circuits had white or black paper sheets fully covering their top thus hiding their identity. For many years Creative tended to use off-the-shelf components and manufacturers' reference designs for their early products. These circuits were featured earlier in various popular electronics magazines around the world. It contained two Philips SAA 1099 circuits, which, together, provided 12 voices of square-wave bee-in-a-box stereo sound plus some noise channels. The history of Creative sound boards started with the release of the Creative Music System ('C/MS') board in August 1987. The pre-Sound Blaster years Creative Music System The creator of Sound Blaster is the Singapore-based firm Creative Technology, also known by the name of its United States subsidiary, Creative Labs. The Sound Blaster family of sound cards was for many years the de facto standard for audio on the IBM PC compatible system platform, before PC audio became commoditized, and backward-compatibility became less of a feature.
