What is ACT ?

ACT is the compressed recording format written by inexpensive digital voice recorders and dictaphones. It stores speech with the G.729 codec at telephone quality, 8 kHz mono, so hours of dictation fit into very little memory. Ordinary media players and audio editors rarely open it, which is why recordings tend to stay on the device until they are converted.
