Atpdec will convert these sounfiles into .png images. For each soundfile up to 4 images could be generated : -1) Raw image : contains the 2 transmitted channel images + telemetry and synchro pulses. - Raw image is not calibrated, so it could be too dark or too light depending of - the recording level. -2) Calibrated channel A image -3) Calibrated channel B image -4) False color image + + 1.

False color image Input soundfiles must be mono signal sampled at 11025 Hz. Atpdec use libsnd to read soundfile, so any sound file format supported by libsnd
