We are going to use the speex format to compress the files. MP3 (or Ogg) is a generalized format for music and such, and thus missing opportunities for compression of voice that speex finds. Speex is a very dominant format, being used in lots of things from Ventrilo to Asterisk. We are seeing compression ratios of 40:1 and even one of 75:1 with "acceptable" quality. This is crucial because the audio will be pushed in real-time on demand to each client from the server.
You guys are welcome to obsess about model numbers of microphones but I think it shows that you are missing the point. As Xillix pointed out, we are not even attempting to get to "pro" quality audio here. This isn't Oblivion, I believe he said.
- Amateur voice actors
- Uncontrolled background environment (machine fans, etc.)
- Low quality mics
- Compressing the bejesus out of the result
We are doing this because we think it will make the game more fun. We're offering to have players help us record because we think it will be fun for people to contribute. If you think it is fun to help write the guide about how to make the best audio, that's fine too, but I don't want to scare off people from trying to record.
If you don't like the end results, you can certainly disable the audio voicing entirely and never have to hear an amateur voice or compression artifacts. :-)
