Thank you for your tip, I really appreciate not being C&D'd.

The sample rate was probably slightly changed to fit the samples into the last sample block without changing the play Mike_Z: (at least the extracted files were ever so slightly distorted when playing with VLC, now they aren't anymore, maybe it was just my imagination) Speeding up the source material will distort the music, this was a problem in one of the updates if I remember correctly. (if there is no loop it doesn't matter if there is silence at the end)Ī block with 2048 samples (ffmpeg, old) is ~46 ms long Sadly the encoder adds silence (something that is not desired when looping) if the music data has ended before the last block is filled. I'm guessing but I think a low block size is needed because a loop can only occur on the end of each block: see here for a technical overview The required FACT chunk is missing (according to Microsoft docs it is required in any non-uncompressed-PCM file to be true to the standard, but not for XAUDIO2 ADPCM) but it doesn't matter if it's streamed.Īdditionally loop information is (probably) given by the SMPL chunk (or it's just a leftover from production) The target format for SkullGirls is the codec 'XAUDIO2 ADPCM' in the container WAV with a fixed bitrate of 385 kb/s (for music) / 192 kb/s (for character sounds) and slightly varying sample rate (around 44,1 k) and a fixed block size of 140 samples (music) / 70 samples (sound).

Ok, research post incoming: (no info for the average user here, just for future reference)įor the music found in music and character sounds: Thanks for pointing me into the right direction. ~ let's have some funĮdit3: It still works (at least for music)Īdpcm.exe -b 128 uncompressedPCM.wav compressedADPCM.wav I did not find a download for XAudio 2, or is adpcm.exe in the Direct X SDK?Įdit: ok, seems to be in the current Win 8 SDK, let's have a look.Įdit2: Yeah it's in the Win 8.1 SDK as well.
