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.

Why Convert ACT files?

ACT recordings come off cheap dictaphones and voice recorders, and the moment you copy them to a computer you find out that nothing wants to open them. The format was never documented by the people who make these devices, so media players, phones, editors and transcription services all pass on it. Converting the recording to WAV or MP3 is usually the only practical way to listen to it, send it to someone or work with it.

Set your expectations by the source. ACT stores speech at telephone quality, 8 kHz and mono, and a conversion reproduces what the recorder captured rather than adding detail the microphone never picked up. For voices that is plenty. Choose WAV when the audio is going into an editor or a transcription tool, and MP3 when you just want a small file that plays everywhere.
