Audio Formats
The type of audio format that you choose to use first depends on
one simple question: Will you be using the Binloop to play only
audio, or will you be playing video? If you are only playing audio,
you can create one of several types of uncompressed audio files.
These file types are discussed in Uncompressed Audio
Formats. If you are creating an MPEG2 Program stream for the
purposes of playing video, you must include an audio track that
is compatible with the Program Stream format. These formats
are discussed in MPEG2 Program Stream Audio Formats.
MPEG2 Program Stream Audio Formats
When encoding video files as Program Streams, it is required
that you have audio along with video. Here are the audio
formats that you are permitted to use within the MPEG2 Program
Stream:
1. MPEG Audio
2. Dolby Digital Audio (AC3)
MPEG Audio Specification
Parameter Options
Format: MPEG-1 Layer I/II, MPEG-2 Layer II
Mode: Stereo, Mono
Sample Rate: *32kHz, *44.1kHz, *48kHz
Max Bitrate: 384kbps
Emphasis: Off
* For synchronization, the Binloop uses a global sample rate
clock used throughout the entire system. This means that it is
ABSOLUTELY CRITICAL that the sample rate used to encode
files matches the sample rate configuration of the Binloop cage.
A mismatch between the two will result in both audio and video
playback issues.
Dolby 

 Dolby Digital Specification
Parameter Options
Format:
Dolby Digital AC3*
Mode: 2.0, 5.1
Max Bitrate: 448kbps
Emphasis: Off
* AC3 audio streams are not decoded in the Binloop. They are
only bitstreamed from the digital audio output of the Binloop. This
bitstream output must be decoded using an external AC3
decoder or A/V receiver.
