Waves Audio Ltd, a provider of audio signal processing technologies, has announced the MX5000, the first of a new family of MaxxDSP chips that implement the company's MaxxAudio technologies. The device uses a high-performance 24bit audio DSP and high-quality ADC and DAC audio converters for a complete digital audio subsystem.

The MaxxAudio algorithms are pre-programmed into the MX5000, eliminating the need for DSP programming or filter design expertise. MaxxAudio is a suite of DSP psycho-acoustic algorithms that compensates for loudspeaker and acoustic limits for the small speakers found in today's CE products such as TVs, multimedia, compact stereos and portable devices. MaxxAudio includes technologies for frequency range extension (MaxxBass, MaxxTreble, MaxxEQ), dynamic range compensation (MaxxVolume), and image expansion (MaxxStereo).

The MX5000 is provided in 40pin 6-by-6mm QFN packaging suitable for the most space limited applications. It uses a 5V analog supply for wide dynamic range on the analog inputs and 1.8V core supply for high performance digital logic. The MX5000 is currently available in sample quantities and will be shipping in volume production in March.
