Sound Effects Replacement

OpenSFX is a free replacement of the base sounds for Manual, so that OpenTTD can be played without requiring the (copyrighted) files from the TTD CD. This potentially increases the OpenTTD fanbase and makes it a true free game.

Technical and licensing details

Sounds should be uploaded as 44,100Hz, 16-bit mono WAV or FLAC files. There will be a new sound file format developed for OpenTTD, likely using .tar files in a manner similar to that of the new sounds. Until then, tools will be made available to enable work to go on using the existing sample.cat format.

For ensuring that resulting sample.cat (or tar) file may be distributed freely with OpenTTD code all sound files must have some of free license. Appropriate are domain Public domain or the Sampling Plus license. Other licenses (like for example Creative Commons -sa -nd -nc or its combinations) are more problematic. If sourcing sound effects from free libraries online, please ensure they are licenced under Public domain or the Sampling Plus 1.0 license.
