SmartWAV 2 is an embedded 14-channel polyphonic audio processor chip, It's aimed to help developers to create stereo audio designs in a very fast and easy way without the need of having experience in handling audio decoding, sampling, mixing, etc.

 

The processor offers 8 modes of operation: slave serial modes, MIDI, and stand-alone modes:


In slave serial modes, the processor receives simple commands from a host microcontroller to execute tasks play(), volume(), advanceTo(), etc, this reduces dramatically the code complexity (audio decoding algorithms) and saves a lot of headaches to the programmer. SmartWAV 2 can play up to 14 channels with high quality stereo sound from a microSD card with universal FAT/FAT32 format. The processor supports 8/16bit, 8Khz-48Khz, mono/stereo, WAVE (.WAV) files with CD Quality.

 

In stand alone modes: with directly connected external push buttons a full multi-trigger/mixing 10-channel audio system can be achieved without the need of any other host microcontroller/processor.

 

SmartWAV 2 is not a programmable device, no IDEs, programmers, nor debuggers are needed, it is a ready to plug and play device.

 

SmartWAV 2 is the most full featured, flexible, powerful and yet easy to use audio processor for embedded systems.
