 circuits, which, together, provided 12 voices of square-wave bee-in-a-box stereo sound plus some noise channels.

These circuits were featured earlier in various popular electronics magazines around the world. For many years Creative tended to use off-the-shelf components and manufacturers' reference designs for their early products. The various integrated circuits had white or black paper sheets fully covering their top thus hiding their identity. 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.

Surprisingly, the board also contained a large 40-pin PGA (Creative Technology Programmable Logic) integrated circuit, bearing a CT 1302A CTPL 8708 serigraphed

 at up to 23 kHz sampling frequency (approx. FM radio quality) and record at up to 12 kHz (approximately AM radio quality). The sole DSP-like feature of the circuit was ADPCM decompression.

In spite of these limitations, in less than a year, the Sound Blaster became the top-selling expansion card for the PC. It achieved this by providing a fully AdLib-compatible product, with additional features, for the same, and often a lower price. The inclusion of the game port, and its importance to its early success, is often forgotten or overlooked. PCs of this era did not include a game port. Game port cards were costly (around $50) and used one of the few expansion slots PCs had at the time. Given the choice between an AdLib card or a fully compatible Sound Blaster card that came with a game port, saved a slot, and included the "DSP" for not much more in price, many consumers opted for the Sound Blaster. In-game support for the digital portion of the card did not happen until after the Sound Blaster had gained dominance.

Sound Blaster 1.5, CT1320C

Released in 1990, the Sound Blaster 1.5, CT1320C, dropped the C/MS chips, which were no longer popular with game developers. Instead, the board had two empty sockets, which could be user upgraded by purchasing the C/MS chips directly from Creative. Otherwise the card is similar to the Sound Blaster 1.0.

The Sound Blaster 16 retained the Yamaha OPL-3 for FM synthesis and a backward compatible programming interface, so most software titles written for the older Sound Blasters and Sound Blaster Pros would run without modification.

Eventually this design proved so popular that Creative made a PCI version of this card. Moving the card off the ISA bus, which was already approaching obsolescence, meant that no line for host-controlled ISA DMA was available, as the PCI slot offers no such line. Instead, the card used PCI bus mastering

Sound Blaster AWE32

 legacy support. Creative's acquisition filled a market segment where Live! was too expensive, and it gave them excellent DOS support, a feature that was proving difficult for companies to get working with PCI cards (as described above in the Sound Blaster 16 section, early PCI audio cards had to work around the missing ISA-DMA lines of the PCI slot to run with existing DOS software, and often the work-arounds did not function well, or worked only in DOS boxes within Microsoft Windows).

Creative released many cards using the original AudioPCI chip, Ensoniq ES1370, and several boards using revised versions of this chip (ES1371 and ES1373), and some with relabeled AudioPCI chips (they say Creative on them.) Boards using AudioPCI tech are usually easily identifiable by the board design and the chip size because they all look quite similar. Such boards include Sound Blaster PCI64 (April 1998), PCI128 (July 1998), Creative Ensoniq AudioPCI, Vibra PCI and Sound Blaster 16 PCI.

These cards were full-featured, but the features were limited in capability. MIDI, for example, was rather poor in quality and there was no ability to customize the sample sets beyond the three pre-made sets (2, 4, and 8 MB) included with the cards. The chips do not support hardware acceleration

).

The EMU10K1 (and its successors) did not use on-card RAM/ROM storage for instrument samples, instead it used a high-speed PCI DMA interface to access sample-data stored in the host-PC's system memory. The EMU needed only a single extra chip to interface with the PCI bus. Not only did this arrangement eliminate the need for on-card storage, it also raised instrument-sample and sound-effect size from the AWE64's 8 MB, to the size of host system memory. The EMU10K1 and FX8010 chips offloaded functions previously handled by separate custom chips.

All members of the SB Live! family were built on the EMU10K1, came standard with four-channel analog audio outputs, and the ubiquitous 15-pin MIDI/Joystick multiport, and similar AC'97 architecture (isolation of ADC/DAC functionality into a separate codec chip.)

Sound Blaster Audigy series

The Sound Blaster Audigy (August 2001) featured the Audigy processor (EMU10K2), an improved version of the EMU10K1 processor that shipped with the Sound Blaster Live!. The Audigy could process up to four EAX environments simultaneously with its upgraded on-chip DSP and native EAX 3.0 ADVANCED HD

 support, and supported up to 5.1-channel output.

The Audigy was controversially advertised as a 24-bit sound card. The EMU10K2's audio transport (DMA engine) was fixed at 16-bit sample precision at 48 kHz (like the EMU10K1 in the original Live!), and all audio had to be resampled to 48 kHz in order to be accepted by the DSP (for recording or rendering to output.)

Sound Blaster Audigy 2 (September 2002) featured an updated EMU10K2 processor, sometimes referred to as EMU10K2.5, with an improved DMA engine capable of 24-bit precision. Up to 192 kHz was supported for stereo playback/record, while 6.1 was capped at 96 kHz. In addition, Audigy 2 supported up to 6.1 (later 7.1) speakers and had improved signal-to-noise ratio

, it has no distinguishable difference from the Audigy 2 ZS. The DSP is identical to the Audigy 2 ZS's but Creative put an "Audigy 4" sticker to cover the chip, making it appear as if it is a new chip. The Audigy 4 Pro is not to be confused with the Audigy 4 (Value) which contains lower quality DACs and does not have golden plated jacks. The Audigy 4 (Value) is more in line with the Audigy 2 Value series. The Audigy 4 had a shorter life span than its predecessors, due to the short window between it and the next-generation Sound Blaster X-Fi.

Sound Blaster X-Fi

The X-Fi (for "Extreme Fidelity") was released in August 2005 and currently comes in XtremeGamer, Titanium, Titanium Fatal1ty Professional, Titanium Fatal1ty Champion and Elite Pro configurations. The 130 nm EMU20K1 (or EMU20K2 for Titanium series models) audio chip operates at 400 MHz and has 51 million transistor

s. The computational power of this processor, i.e. its performance, is estimated as 10,000 MIPS, which is about 24 times higher than the estimated performance of its predecessor, the Audigy processor. Beginning with the 2008 Titanium models, newer X-Fi cards switched from PCI to PCI Express

 5.0 which supports up to 128 3D-positioned voices with up to four effects applied to each. This release also included the 24-bit crystallizer, which is intended to pronounce percussion elements by placing some emphasis on low and high pitched parts of the sound. The X-Fi, at its release, offered some of the most powerful mixing capabilities available, making it a powerful entry-level card for home musicians. The other big improvement in the X-Fi over the previous Audigy designs was the complete overhaul of the resampling engine on the card. The previous Audigy cards had their DSPs locked at 48/16, meaning any content that didn't match was resampled on the card in hardware; which was done poorly and resulted in a lot of intermodulation distortion. Many hardcore users worked around this by means of resampling their content using high quality software decoders, usually in the form of a plugin in their media player. Creative completely re-wrote the resampling method used on the X-Fi and dedicated more than half of the power of the DSP to the process; resulting in a very clean resample.

 and/or subwoofer speaker instead)


Up until the AWE line, Creative cards has short text inscriptions on the backplane of the card, indicating which port does what (i.e. Mic, Spk, Aux In, Aux Out). On later cards, the text inscriptions were changed to icons. With the latest cards from Creative, the cards were changed to use numbers as the ports are flexi-jacks and can have different functions assigned to them at run-time (i.e. changed from speaker output to mic in), but a color overlay sticker is included with retail units to help consumers identify the commonly used functions of the ports in their default modes.

Driver software modification (soft mod)

Some drivers from the Audigy 2 ZS have been soft-modded by enthusiasts. These can be installed on Creative's older cards, including Sound Blaster Live!, Audigy, and Audigy 2. It has been claimed to offer improved sound quality, hardware acceleration of higher EAX versions in games, 64-channel mixing for Audigy 1, and an overall improvement in the card's performance. Several forum posts across the web have reported favorable results with this technique, excepting Live! users where the drivers only add the ability to use the newer software applications (i.e. the newer mixer applet). Comments on forums from developers of the software mod have said that Live!'s hardware is not capable of EAX3 nor 64-channels of hardware sound mixing.

Later, in 2004, Creative released updated drivers top-to-bottom for the Audigy through Audigy 4 line that put these cards basically at feature parity on a software level. As of 2006, the entire Audigy lineup uses the same driver package. DSP decoding at the driver level on other cards than Audigy 2 ZS and 4 is still not supported by official drivers, but it works with soft-modded drivers on the other cards with hardware DSP (like Audigy 2 6.1).

When Windows Vista was released, there was only a single beta driver for the Creative Audigy series that was usable on the operating system with minimal functionality and frequent instability reported by users. A Creative Forum activist named Daniel K. (His real name is Daniel Kawakami who is from Brazil) modified drivers from the X-Fi and applied it to the Audigy and Live! series, restoring most if not all of the features that came with the original XP setup CD in Vista. X-Fi drivers have noticeably better sound quality under Vista, and more bug fixes because of the newer build (last modified version is 2.15.0004EQ April). He managed to enable the X-Fi Crystallizer to work on Audigy series cards in software, however because of the patents involved, he was forced to remove all the modified drivers and DLL patch. The event ended as a PR disaster for Creative as they put legal pressure on a user who had succeeded in creating working Vista drivers where Creative had failed, especially on the Creative Forum and technical blog sites. It is possible that many previously loyal customers refused to buy Creative products and turned to other brands as a result.

Daniel K has since stopped developing modified support files for the above sound cards, however some of the files (as of July, 2008) may still be hosted on individual tech/blog sites. Creative has since then released a newer official Audigy Vista driver (2.18.0000 as of July 28, 2008) due to public and consumer pressure.
