The following sections outline which audio formats are supported by BrightSign players.
XTx43, 4Kx42, XDx33, XDx32, XDx30, HDx23, LS423, HDx22, HDx20, HDx10, LSx22, AU320:
- AAC audio in H.264 Video (CBR only; no VBR support)
- MP3 audio files as stereo or mono at a 48 kHz or 44 kHz sampling rate (MPEG1/MPE2 Video)
- WAV audio files as stereo or mono (32-bit/96kHz output is supported on all models except the HDx20, HDx10, and AU320)
- M4A and AAC audio files (requires BrightAuthor version 4.3.0.x or later; not supported in BSN presentations)
- Dolby Digital (AC3) 5.1 audio in an MPEG2 or MOV video (pass-through over HDMI or TOSLINK w/ expander). Other multichannel audio formats may work as pass-through, but they are not officially supported.
Important: All tracks must have the same sampling rate if you plan to output multiple audio tracks simultaneously (from either audio or video files).
XTx43, 4Kx42, XDx33, XDx32, XDx30, HDx23, HDx22, LS423:
- FLAC and Vorbis codecs (along with the .ogg file format)
- MP3 audio files as stereo or mono at a 48KHZ sampling rate
- MP3 audio files as stereo or mono at a 48KHZ or 44KHZ sampling rate
- WAV audio files as stereo or mono
- Dolby Digital (AC3) 5.1 audio in a video file (decode or raw pass-through)
- PCM Audio in a video file (LPCM)
- To play videos with surround sound, you must encode an AC3 audio layer along with an MPEG2 video layer.
- BrightSign players do not decode surround sound (AC3) audio; but the audio can be passed through to a decoding device over HDMI of SPDIF.
- If you are using Adobe Premiere to encode the video with the SurCode codec for audio, ensure that SurCode is in BluRay mode, not Dolby Digital mode.
