SMARTWAV 2 Datasheet SmartWAV 2 processor internally is a sophisticated multi-task system, it processes individual .wav tracks mounted on each of the 14 channels, mixing those with a master sample rate and a master gain control, this process is automatically. The master sample rate is how the processor outputs audio samples; this parameter is global for all 14 channels. The master gain control (master mixer volume) is a global parameter that affects all the 14 channels.
SMARTWAV 2 Datasheet Point A and Point B are markers that the processor handles for each channel for rewind, loop and other functions. Each time a track is mounted, the points A and B are set at their defaults: A-Start of track and B-End of track (blue color). User can later set and re-define those A and B points (green color) by the respective command.
SMARTWAV 2 Datasheet 3- Operation Modes: The module offers 8(eight) modes of operation; selection between modes is by setting the external pins M0, M1 and M2, the next table details how mode is selected by tying the M0, M1 and M2 pins to VCC or GND: SmartWAV 2 M0, M1, M2 Pin Mode Selection Table: Mode M0: Standard Serial M1: Rewind Play (always) M2: Rewind Play / Pause M3: Rewind Play(hold) / Pause M4: MIDI Serial M5: Play / Pause M6: Play(hold) / Pause M7: Music player M2 Pin GND GND GND GND VCC VCC VCC
