What is ADTS?
ADTS stands for Audio Data Transport Stream. ADTS is a container for AAC encoded audio. It consists of a series of frames, each frame having a header followed by the AAC audio data. The formats are defined in MPEG-2 Part 7, but are only considered informative by MPEG-4.

AAC compressed audio data may be stored in either an MPEG-4 container file format (.mp4, .m4a) or more basic MPEG-2 based file formats such as a ADTS (.aac, .adts) Audio Data Transport Stream file.

An MPEG-4 file contains a header that includes meta-data followed by "tracks" which can include video as well as audio data, for example, H.264 encoded Video and AAC encoded Audio.

ADTS in contrast is a streaming format consisting of a series of frames, each frame having a header followed by the AAC data.

Therefore, a decoder can start playing a ADTS stream at any point within that stream making it ideal for "radio" like applications. To decode an MPEG-4 file however, the file header must first be read in order to properly playback the file.

What is AC3?
Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound. The most elaborate mode in common usage involves five channels for normal-range speakers (20 Hz - 20,000 Hz) (right front, center, left front, right rear and left rear) and one channel (20 Hz - 120 Hz) for the subwoofer driven low-frequency effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates up to 48kHz. Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The LaserDisc version of Clear and Present Danger featured the first Home theater Dolby Digital mix in 1995.
