    sfxr – sound effects for all!

    Posted by

    Been tinkering with this over the last couple of days.

    EDIT: Official sfxr homepage – http://www.drpetter.se/project_sfxr.html

    As the audio geek I am, I find it a bit unfortunate that most LD48 entries are usually silent. I figure it’s probably due to the authors not having a quick ‘n’ easy application at hand for making sound effects and therefore neglecting that aspect of the game in favor of code and, usually, graphics. Even simple sound effects can add a huge amount of immersion and fun to a game, though.

    What I present here is, if you will, an MS Paint for sound effects… or something along those lines. It’s meant to make it dead easy for anyone to whip up a few simple sound effects and save them as .WAV files for playback using most game/media libraries like SDL or pygame.

    Basic usage involves clicking the left-most buttons to automatically generate random sounds loosely targeted at certain categories. For more advanced users it’s possible to spend some additional time to manually create fairly varied and interesting sound effects.

    The interface is based entirely around sliders for controlling sound parameters, along with a few buttons. Even if you don’t want to spend time learning about all the sliders you can still have some fun just hammering away at them and listening to the various sounds that come out.

    Hopefully this will mean that there’s no longer any valid excuse for anyone to get N/A in sound!

    Download: sfxr.zip (win32, 48 kB) – Latest update: 2007-12-15 (see screenshot)

    EDIT: Apparently it sort of works in wine 0.9.50, though with some stability issues. Fortunately though, the good Gerry JJ/mjau managed to port it properly. Here’s a copy of his post:

    I ported DrPetter’s excellent sfxr (info) to SDL, so it can now be compiled and run natively in Linux!

    Download: sfxr-sdl.tar.gz

    Just type ‘make’ to compile. You need SDL and GTK 2.

    Source code is obviously included in the portable archive, and anyone is free to use or modify it for anything they please. There’s no need to credit me, although it would be nice if you did. I would also appreciate a little email note if you do create something cool based on my code.

    If I get around to making a little update I’ll include source code in the win32 archive as well.

      What about a library that generates SDL Mix_Chunk?

      Awesome tool, but I’m reluctant to use it as my anti-virus (kaspersky) goes crazy thinking its a key logger :(

      THANK YOU for the simple brilliance that is sfxr — I’m enjoying the Cocoa Mac port, cfxr, right now. And I also made a fun video tour of it:

      Maybe you need a mirror, the download website is down from days…

      Hello,

      I know the website to download Sfxr is down. So I decided to share my ressource about Sfxr and Cfxr :

      http://www.woolyss.free.fr/chipmusic.php#generators

      There is an audio demo of Sfxr too !
      It’s my website about chipmusic, chiptune, 8bit music…

      If DrPetter is disagree, tell me. I will delete ZIP archive. Thank you.

      I made a Flash port of sfxr: as3sfxr! That means a cross platform web app that does everything sfxr does and more. I even stayed true to the original design
