Horn

Car horns need to be saved as one of the following, and placed within the cars .zip file.

horn.wav (Uncompressed WAV, pcm, 8 or 16 bit, mono or stereo 8-44kHz))
horn.ogg
horn.mux

If the sound effect is in stereo it must be converted to mono. There can only be one horn per car.

Considerations

Keep file sizes down to reduce the strain on the peer-to-peer system.
Amplify the sound so it can be heard without distortion.
Use Locator Files if your connection doesn not support peer-to-peer.
