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 [[Environmental audio extensions|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&nbsp;kHz (like the EMU10K1 in the original Live!), and all audio had to be resampled to 48&nbsp;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&nbsp;kHz was supported for stereo playback/record, while 6.1 was capped at 96&nbsp;kHz. In addition, Audigy 2 supported up to 6.1 (later [[7.1 surround sound|7.1]]) speakers and had improved [[signal-to-noise ratio]] (SNR) over the Audigy (106 vs. 100 [[decibels]] ([[A-weighting|A]])). It also featured built-in [[Dolby Digital|Dolby Digital EX]] 6.1 and 7.1 decoding for improved DVD play-back. The Audigy 2 line were the first sound cards to receive [[THX]] certification.

''Sound Blaster Audigy 2 ZS'' (September 2003) is essentially an Audigy 2 with updated DAC and [[Operational amplifier|op-amps]]. Audigy 2 ZS uses the [[Cirrus Logic]] CS4382 DAC together with the op-amps and can produce an output SNR of 108 dB. There were a few slight [[printed circuit board]] modifications and [[7.1 surround sound|7.1]] audio support was added.

''Sound Blaster Audigy 4 Pro'' (November 2004)<ref>{{cite web|url=http://reviews.cnet.com/sound-cards/creative-sound-blaster-audigy/4505-9334_7-31229395.html|title=Creative Sound Blaster Audigy 4 Pro|website=Reviews.cnet.com|access-date=12 July 2016}}</ref> was an Audigy 2 ZS with updated DACs and [[Analog-to-digital converter|ADCs]], the new DAC being the Cirrus Logic CS4398, boosting the output SNR to 113 dB. Other than a [[breakout box]], 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 Audigy Rx'' (September 2013) is similar to the ''Audigy 4'' but with a dedicated 600-ohm headphone amplifier and a [[PCIe]] 1x interface.<ref>{{cite web |url=http://us.store.creative.com/Sound-Blaster-Audigy-RX/M/B00EO6X7PG.htm |title=Sound Blaster Audigy RX &#124; Creative Labs Online Store |access-date=2013-09-23 |url-status=dead |archive-url=https://web.archive.org/web/20130928061052/http://us.store.creative.com/Sound-Blaster-Audigy-RX/M/B00EO6X7PG.htm |archive-date=2013-09-28 }}</ref>

''Sound Blaster Audigy Fx'' (September 2013) also features a 600-ohm amplifier and a PCIe interface, but lacks the EMU10K DSP.<ref>{{cite web |url=http://us.store.creative.com/Sound-Blaster-Audigy-Fx/M/B00EO6X4XG.htm |title=Sound Blaster Audigy Fx &#124; Creative Labs Online Store |access-date=2013-09-23 |url-status=dead |archive-url=https://web.archive.org/web/20130929170447/http://us.store.creative.com/Sound-Blaster-Audigy-Fx/M/B00EO6X4XG.htm |archive-date=2013-09-29 }}</ref>
