Random synthesized fire alarm
« on: August 22, 2018, 06:06:17 PM »
I was working on a project that needed a fire alarm sound effect, and I was a bit worried about possible, albeit unlikely, copyright issues if I was to use a recording of the sound a real alarm makes. So, I made my own to avoid that issue, and I'm posting it here as well in hopes that maybe someone will find it useful. You can use them for whatever you want, consider them to be public domain or an equivalent license such as CC0 or WTFPL.

Opus version (smaller) and WAV version (in case you can't play Opus) are both attached.

I've never seen an OPUS file before. Is that based on a more well-known codec or is their only one specific program that can read that type of file?

Opus is a standard codec, intended to be the successor to Vorbis. It's a free standard and everything, but not very widely supported yet because it's fairly new. Some players, including VLC and anything based around a recent version of FFmpeg, can read these files fine. It does manage to compress very well, though, as with most music very good quality can be reached around 64kb/s and effectively perfect at 128kb/s, and it even manages to beat AAC in certain tests.
