1// 0x01A527DB audio snr (voice/aud)
1// 0x01EEF63A audio sns (fx/music)
1// 0xB1CC1AF6 Movies

Movies strangely enough seem to be the easier of these to decode since there's a known spec for them. They are basically a general EA container format with encoded pieces of data stored in them using (luckily) known codecs.

The movies are VP6 video encoded with SCxI/GSTR/adpcm_ea_r3 audio

researched by lenglel: snr Codec Info: If the first byte is 05, that means its using EALayer3 codec. encode/decode via ealayer3.exe http://bitbucket.org/Zenchreal/ealayer3/downloads note: there is no pre-compiled mac version, but source code links are posted on the same page below the windows binaries.

If the first byte of the snr data is 04, that means its using the EA XAS ADPCM codec. encode/decode via ffmpeg.exe. http://www.ffmpeg.org

If its anything else, the codec is currently unknown.

sns Data Info: This is the actual encoded audio data.
