Well as sugested by Olnorton i copy the wav files from baldurs gate 2 into my sounds in baldurs gate 1 so i could have them in spanish , now the problem is that those voices sound so low in comparison with the rest of the voices that came with the game , so ive been looking around the web for a program that could increase the voulme of this wav files , and got a program called Audacity , problem is this program dont even recognize the wav file from my baldurs gate 2 but does recognize the ones in enlish , its a bit frustrating xD , im not very computer clever so it takes me a good amount of time to search for all this things and when i see i can just go no further i must ask for help , so if anyone does know how i could increase the volume of these files it would be greatly apreciated :)
Edit : on a side note i have even tried with WAV to MP3 converter programs to see if i could once its a mp3 control the volume but the diferent programs do not recognize the files , tried with the icewind dale voice sets in english as well and it didint work so im not even sure if its a WaV file anymore , im out of ideas by this point :P

There are two tools there, one is an editor and the other a converter. Looks like BG2 sound files aren't WAVs, they are ACM.

Hi Neant i had seen that tool in a spanish forum but they didint say i had to open in dos :P but anyways the tool said that the file is not a Acm so hence i cant convert it , wich is starting to be a bit stresfull since when i open properties in the file it does show up as a Wav file then when i get programs to do it i cant , ill try and see if i can find a program to convert wav2acm but this is starting to be such a hustle , its not a major problem really but the diference in volume bettewn the voices on my group and that of my main char is just a lot from 1-10 is like they was at 8 volume and me at 3-4 like really low xD

Ive just downloaded the program but im trying to figure it out , alltough the describtion mention weidu in the page and im not using eather weidu or tutu or anything , for that matter i play baldurs gate as it comes without mods :P ill try messing around a bit with it but so far im not understanding much of it hehe

Edit: i do belive i must have weidu aye , just checked the files and the music is indeed ACM but what im trying to work with is the sound files the voices of the chars , my main char in this case and its listed as WAV , but im starting to think its weird because no Wav program ive downloaded so far recognizes it as a WAV xD
2 Edit: ok from what ive gathered around the web the sound files are not WAV but actually WAVC and to change them you need a tool for it unfortunatly all ive found are old pages that dont have the links anymore so guess this means its the end :P
3 Edit: ok i have figure out how to work the tool you mention , now the Audacity tool can open the files , alltough im doin one at a time so its goin to be a bit of time before im done , then ill try them ingame and see if they work as intended :) if it does work i can call this finished and give you the answer since you apointed me to that tool :)
Final Edit :P after a good wile changing volume in each of my files i tryed them after in game and they did sound as loud as the rest of my party , so thanks a lot for pointing me on the right direction ,glad it finally got fixed i was about to give up haha
