Audio Formats

this page covers the audio modes that different models support, recommended audio modes, and additional notes supported audio xc2055, xc4055 and xt2145 the audio modes supported by these player models are stream / codec name common name aac aac ac3 ac3 or dolby digital eac3 eac3 or ac3+ or dolby digital plus opus opus mp2 mpeg1 layer 2 or mp2 mp3 mpeg1 layer 3 or mp3 vorbis vorbis dts dts audio pcm xxxxx pcm audio (all types are supported) truehd dolby truehd mlp meridian lossless adpcm xxxx adpcm audio (all types are supported) flac flac au335 series 4 additional player audio format information xtx44, xdx34 flac codec (with the ogg file format) opus codec xtx43, xdx33/32, hdx24/23/22, ls424/423, 4kx42 flac and vorbis codecs (with the ogg file format) hd600 mp3 audio files as stereo or mono at a 48khz sampling rate hd2000 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) recommended formats aac audio in h 264 video (cbr only) mp3 audio files as stereo or mono at a 48khz or 44khz sampling rate (mpeg1/mpe2 video), with a maximum bit depth of 16 bits, and a maximum bit rate of 320kbit/s wav audio files as stereo or mono we recommend a maximum bit depth of 24 bits at a sampling rate of 96khz, 48khz, or 44 1khz (except for the hdx20, hdx10, and au320, which may require a lower bit depth) m4a and aac audio files (note that if you are using brightauthor, you must be on version 4 3 0 x or later and these formats are not supported in bsn presentations) notes to play videos with surround sound, you must encode an ac3 audio layer along with an video layer in a supported codec and format all tracks must have the same sampling rate, or you must enable the audio docid\ ps 4gxslstoqhwbvlzslo feature, if you plan to output multiple audio tracks simultaneously (from either audio or video files) series 4 and earlier 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 two channel pcm and aac currently requires specific settings and a plugin for brightauthor classic and brightauthor\ connected, or else the output will be stereo down mix because they're handled in the "multichannel" output routing which currently isn't exposed in the ui see https //brightsign box com/s/ni3dn4eztw2jjr4sgo14jpgjkigj36jj https //brightsign box com/s/ni3dn4eztw2jjr4sgo14jpgjkigj36jj and note that audio that the player can decode with 2 or fewer channels is routed as normal "stereo" audio audio the player cannot decode, regardless of channel count, is routed as "compressed" audio audio the player can decode with 3 or more channels is routed as "multichannel" audio and that's where the ui doesn't match the output possibilities the pass pass throughthrough option currently routes only "compressed" audio through to the output "multichannel" audio isn't affected and therefore gets down mixed to stereo and output the plugin enables "multichannel" audio to go out through hdmi when in fixed audio mode we do not decode dolby ac3, but dolby digital (ac3) 5 1 audio can be used in an mpeg2 or mov video (pass through over hdmi or toslink with an expander) other multichannel audio formats may work as pass through, but they are not officially supported dts audio in the ts (transport stream) video container can be used as pass through dts in other containers (mov, mp4, mkv) are not currently supported the xtx44 currently does not support dts audio in any container brightauthor classic version 8 0 73 fixes a bug that caused ac3 audio to play back louder than expected gefen hdmi to hdmi plus audio converter, (sku gtv hdmi 2 hdmiaud, upc 845344056111) only supports multichannel analog output for lpcm 5 1 audio input it does not output analog for compressed audio formats
