UPDATE: Wwise Sound Tool BETA v.0.9.9 This tutorial shows how to translate the original DiRT Rally Co-Driver callouts into your own language or switch to a different co-driver voice using Wwise Sound Tool by Xaser (v.0.9.9). If you can find out where the notes are called during a stage then you can tweak them as well. This method does not work for countdown and messages callouts. Tested on Windows 10. Create new folder named Original and extract contents of wwise.7z here. Rename Wwise Sound Tool.exe to wst.exe and copy your chosen soundbank to this folder (s_cd_panzerplatte_rally_01_fwd.bnk used as an example). Duplicate the folder and rename it Custom. Open Command Prompt within Original folder and run following commands: wst.exe extract_all s_cd_panzerplatte_rally_01_fwd.bnk wst.exe decode_all wem Using wav files as a reference create or modify your custom calls in your favourite audio editing software, remembering that they have to be exactly the same length as their counterpart originals. If your call is too short, simply add silence at the end. Export to 16-bit PCM and save as .wav in Custom folder. Open Command Prompt within Custom folder and run following commands: wst.exe encode_all wav wst.exe pack_all wem s_cd_panzerplatte_rally_01_fwd.bnk If the process of packing files is unsuccessful then compare all your custom .wem files in Custom folder with original ones extracted from the soundbank in Original folder. All of them have to be the same kB as their counterparts. Replace the original soundbank in your DiRT Rally installation folder with your custom one. If you want to revert back to original calls use a backup or reinstall your language in Steam. I strongly advise to use French/German/Italian/Spanish version of Route Notes for translation because they contain only the necessary calls as opposed to English version, which uses 4 intonations of the same call. Although translated calls are not as detailed and correct as English notes this simplifies the job as you would have to translate and replace 4 times as many samples as with other languages (the sound files are scattered all around the soundbank and unless someone can read the binary files inside them it is very hard to establish where the calls appear during a stage). Use at your own risk, however there is no messing with physics so it is safe, I guess CREDITS: Xaser - Wwise Sound Tool BETA 0.9.9 versedi - batch processing code (obsolete) Codemasters - DiRT Rally!
