[Request] Bugs Bunny: Lost in Time (PC) - Decode or Encode for audio ".xa" type file

Featured Replies

Anyelse know some about .xa audio files from the bugs bunny lost in time for pc version? any idea? , the unique info i know from this type file, is that, for example in audio data folder from game i found "speech.xa"so could be encoded in format ADPCM 4 bit, so what i did encoded a new file sound cleanest, im taked from ps1 extraction in wav format and sincronized in timeline im export with extension.vox a renamed in .xa,but didnt work, for case of the original file i tried decoded but sound not its very clean,be listening but with a lot of noise similar to a old radio, im import this original file in "audacity" to VOX ADPCM in frecuency 88200hz Mono for get audio sound in correct tempo, but sound contained these noises previously mecioned...  maybe this file it was encoded or encrypt with special codified for this game or maybe not ,really i dont know..if you know something about types .xa files  im apreciated any  info .. anyway, thank.. for listen.

It's a headerless stereo 44100Hz IMA ADPCM audio
You can use this tool (for some reason decoding doesn't work but encoding works fine though)
https://github.com/eurotools/es-ima-adpcm-encoder-decoder
If you can't find the download links:
https://github.com/eurotools/es-ima-adpcm-encoder-decoder/releases/tag/3.5.0.0

Thanks for info, but lamently dont working in game, i tried in 4 versions of my source in format wav, compiled working to adpcm, but inside from game dint work, im share my samples cleanest for test.. 

Samples:

NOTE: i compared size by size betwen adpcm file with original .xa file and so very similar in its full size, in case for "speech03_44100_Stereo" and "speech03_88200_Mono" size = 33.4 MB  and .xa original size = 34.4 MB , in text decodified hex its more similar  "speech03_44100_Stereo.adpcm"  but dont listen fine in game.
