I've been playing around with the Music.txt file recently and made a few interesting discoveries: #1, I think I've finally nailed down what is causing the crash with certain MP3 files: It seems to be related to the ID3 tag.... MP3 files created by using Windows Media Player or iTunes would ALWAYS crash the game, but when I used a certain Freeware program called SUPER to convert those files to WAV, then used an old-ass program called Audio Catalyst (it was made for windows 95/98 ) to convert those files back to MP3 format, but with blank ID3 tags, they worked perfectly with no problems whatsoever. Furthermore, for those who don't have Audio Catalyst, you can just use SUPER to convert the WAV files back to MP3 format, and they will work as well. (I had a few files I converted from other formats using SUPER to MP3 and they all worked).... The only problem is that SUPER will add the original extention to the converted files, so by the time you get done converting the files, your file will be "Songname.mp3.wav.mp3" which will require you to manually edit every single filename. Another program that works is VLC media player, but it can only convert one file at a time.... I haven't tried Audacity or any of the other free music editing programs yet, but I'm planning on getting Audacity tonight and will post any updates when I get done giving it a thorough shakedown. #2: Having taken care of the issues in #1, I'd like to re-emphasize the 44.1 KHZ sampling rate: Even though odd-ball sampling rate songs played after I sent them through my conversion carousel to delete the incompatible ID3 tags (or whatever it was that was causing the crash), if the sampling rate was not exactly 44.1 kHz, the song would either sound like Alvin and the Chipmunks or like a tape recorder with almost-dead batteries... I.e. the songs would be noticeably too slow or too fast. #3: Finally, the Music.txt file can also handle WAV files, so you can avoid most of the problems by just using WAV format, however that will hog up your HD space. Here's the free programs that I used that are known good for converting sound formats: SUPER... Also good for converting lots of images or rendering a video into a series of images and vice-versa. VLC Media Player Free & Open Source software... I personally haven't used Windows Media Player ever since discovering this program (it can play and/or convert REALLY obscure/obsolete media formats, such as Amiga MOD files!) Hoped this helped somewhat.
