The Audigy SE and Audigy Value both carry the SB0570 model number. With these cards only one of the mic, line in, or AUX sources may be unmuted at a time. With the CA0106, the SE/Value are limited to 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. The Audigy SE (SB0570) and Audigy Value (SB0570) are stripped down models, with a less expensive CA0106 audio-controller in place of the EMU10k2. This variant (SB0160) uses the full EMU10K2 chip (CA0100 chip ) and is, as a result, quite similar in feature set. The ASIO and break out box features were an attempt to tap into the "home studio" market, with a mainstream product. Some versions of Audigy featured an external break out box with connectors for S/PDIF, MIDI, IEEE 1394, analog and optical signals. Īudigy card supports the professional ASIO 1 driver interface natively, making it possible to obtain low latencies from Virtual Studio Technology (VST) instruments. (A resulting class-action settlement with Creative later awarded US customers a 35% discount on Creative products, up to a maximum discount of $65.)Īside from the lack of an end-to-end path for 24-bit audio, Dolby Digital (AC-3) and DTS passthrough (to the S/PDIF digital out) had issues that have never been resolved. This fact was not immediately obvious in Creative's literature, and was difficult to ascertain even upon examination of the Audigy's spec sheets.
So despite its 24-bit/96 kHz high-resolution DACs, the Audigy's DSP could only process 16-bit/48 kHz audio sources.
The Audigy and Live shared a similar architectural limitation: the audio transport (DMA engine) was fixed to 16-bit sample precision at 48 kHz. The audio processor could mix up to 64 DirectSound3D sound channels in hardware, up from Live!'s 32 channels.Ĭreative Labs advertised the Audigy as a 24-bit sound card, a controversial marketing claim for a product that did not support end-to-end playback of 24-bit/96 kHz audio streams. The Audigy cards equipped with EMU10K2 (CA0100 chip) 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.
