First Generation

The Audigy could process up to 4 EAX environments simultaneously with its on-chip DSP and native EAX 3.0 ADVANCED HD support, and supported from stereo up to 5.1-channel output. The audio processor could mix up to 64 DirectSound3D sound channels in hardware, up from Live!'s 32 channels.

The Audigy was advertised as a 24-bit sound card. However with some controversy, the Audigy's audio transport (DMA engine) was fixed to 16-bit sample precision at 48kHz (like Live!), and all audio had to be resampled to 48kHz in order to be rendered through its DSP, or recorded from its DSP. As a result, the card did not support playback of individual audio streams at 24-bit / 96kHz precision through its 24-bit / 96kHz DACs, a fact that was not immediately obvious to those examining the spec sheets.

Creative later gave customers in the US who purchased an Audigy card 35% off a Creative product up to a maximum of $65 in a class-action settlement.

Despite being a high end card, the passthrough of Dolby Digital and DTS streams to the SPDIF digital out has issues that Creative does not appear to want to address since the product has reached its End of Life.

First generation break out box

Some versions of Audigy also featured an external break out box with connectors for SPDIF, MIDI, SB1394, analog and optical signals. The significance of the break out box was that it was the first physical sign that the "home studio" was for the first time becoming a mainstream market.

Note that Audigy card supports the professional ASIO 1 driver interface natively, making it possible to obtain low latencies from Virtual Studio Technology (VST) instruments.

Sound Blaster Audigy ES

This variant uses the full EMU10K2 chip and is, as a result, quite similar in feature set. It is only missing its FireWire port.[1]

Sound Blaster Audigy SE & Audigy Value

The Audigy SE and Audigy Value are stripped down versions of the Audigy, with software-based EAX 3.0 (upgraded to software-based EAX 4.0 with a driver update), no advanced resolution DVD-Audio Playback, and no Dolby Digital 5.1 or Dolby Digital EX 6.1 playback. It lacks the EMU10k1/10k2 processor, instead using a CA-0106 Family chip. As opposed to the rest of the Audigy series, the SE is a low-profile PCI card.

Sound Blaster Audigy LS

Similar to the Audigy SE in that it supports neither hardware acceleration nor FireWire. [2]

Second Generation

The Sound Blaster Audigy 2 (SB0240) (September 2002) featured an updated EMU10K2 processor, sometimes referred to as EMU10K2.5, and had an audio transport (DMA engine) that could support playback at 24-bit precision up to 192kHz (2-channel only. 6.1 limited to 96kHz) and recording at 24-bit precision up to 96kHz, thereby overcoming the single biggest criticism of its predecessor. However, the DSP again was limited to 16-bit at 48kHz, so all DSP effects had to be disabled to prevent harmful resampling. Audio using 96kHz or 192kHz was decoded directly by a section of the card known as "p16v." For DSP effects the lower half (48kHz) of the stream was sent to the DSP and mixed with the rest of the signal.

The Audigy 2 supported up to 6.1 speakers and had improved signal-to-noise ratio (SNR) over the Audigy (106 vs. 100 decibels (A)). Audio output was supplied by the AC97 codec on the front outputs and I2S on the rear. It also featured built-in Dolby Digital 5.1 EX (which is technically 7.1) decoding for improved DVD play-back. A IEEE-1394 (FireWire) connector was present in all modifications except Value.

Audigy 2's 3D audio capabilities received a boost when compared to its predecessors. Creative created the EAX 4.0 ADVANCED HD standard to coincide with Audigy 2's release. The chip again can process up to 64 DirectSound3D audio channels in hardware. It also has native support for the free and open...(and so on)
