High Definition Audio Player Features Low Power Consumption
austriamicrosystems announces its model AS3532 music player sub-system with a core that is based on an audio engine and audio post-processor which act as co-processors to an ARM central programmable unit. The audio engine, in a fully hardwired context, executes the decompression and playback of most popular compressed audio formats, such as MP3, WMA and AAC, for the least amount of power consumption with zero CPU load. The audio post-processor implements an asynchronous sample rate converter (ASRC) with near transparent quality, a multi-channel mixer with limiting function and a 10-bands graphics equalizer. It supports 192 KHz sample rates at 24 bits dynamic range for high definition audio processing. The audio sub-system includes a stereo PDM digital microphone input, completing all audio requirements for mobile phones.
