The FireWave is a device that is, essentially, an external FireWire soundcard made by Griffin Technology as a third party accessory for Apple Inc.'s line of personal computers.

FireWave uses the FireWire (IEEE 1394) port of the Mac as an audio output to its Dolby Digital sound processing hardware, effectively acting as an external soundcard.

Griffin Technology's product website explains that FireWave uses the Dolby processors to allow the user to connect a 5.1 surround sound system. Speakers are then connected directly to FireWave's speaker terminals (three female 1/8" stereo connectors). Many different sound setups and configurations are possible, using a combination of Griffin's included FireWave software and Apple's "Audio MIDI Setup" utility.

Sadly, Griffin Technology's website lists the Griffin FireWave as a discontinued item.

    • Here we have the Micronas MAS 3529H Dolby Digital and Mpeg2 Layer 2 Audio Decoder. Its the heart of the sound card, without it, there would be no 5.1. Dolby labs made a contract with Micronas to manufacture these chips under specifications.

    • The MAS 3529H decoder IC acts as a complete implementation of 5.1 DTS and Dolby Digital/Pro Logic II decoders. On the chip’s 8-channel output an Lt/Rt or Lo/Ro downmix is available simultaneously to the multi-channel audio for recording or headphone usage.

    • The chip right below it is the Xilinx XC9536XL High Perfonmace CPLD (Complex Programmable Logic Device). It works with the Wolfson chip to calculate delay time of the center and surround speakers.
