increpare's browser sfxr descendant (current app is Bfxr2 in JavaScript). More parameters than jsfxr, plus a port of obiwannabe's footstep generator. Use it when ChipTone's CC0 output grant is what you wanted and jsfxr is too thin, knowing this page does not CC0 the WAVs. The software is MIT. Homepage About does not discuss output ownership. Sounds you generate are not a redistribution of someone else's pack, but that is inferred, not quoted.
