This is really beautiful - is there any chance that a version could be created for Mac OS X, or online, or javascript - some sort of standalone that would work on a Mac?

I ask because this application can make some rad percussive sounds and it would go GREAT in Renoise!

Somehow. Can't be opened. Why is this?

The windows download link detected as malicious file


"Cannot create OpenGl context attribs" shows this message and does not open the program

I don't know why but it seems like it won't export for me.

I have no idea why xd

Anyone knows the issue?


really great and easy to understand, i'll make sure to recomended it



Huge range of sounds can be made with this tool. Not sure what J,S,H buttons are. Someone below said Jump, Shoot and Hit, but I still don't quite get what that means. Regardless, love this tool a lot.

actually slaps


Any chance you can add an explanation for all the buttons? I had to work out what the boxes next to each name did myself and I still have no idea what J S and H do.  Cool stuff though


I assume Jump, Shoot, Hit (as seen in Sfxr/Bfxr)

Perfect thank you, I was confused but that makes a lot of sense



Not even 5 minutes in and I'm already in love with the sounds that this generator produces. Thanks rxi, this is amazing!


Thank youuu


Hi, just got myself Sfxia and it's great! I'm happy that it sounds slightly different than BFXR. I'm wondering if you're going to expand on it - adding more presets etc.?

Could you explain how this differs from BFXR? I like some of the sounds this tool makes but it seems to be missing a few things BFXR has, like choosing the type of waveform for example.

You're right that the tool lacks some features that BFXR has, though not the waveform one specifically (this is the "Mode" slider). Without going too in depth, both tools differ in how they synthesise sound; the goal isn't for sfxia to be a superset of BFXR but to be a tool separate to it that produces sounds that are typically different to what it would produce.

Cool, thanks for the explanation!


i understand nothing, but looks cool

Please make 32bit binary for Windows.

 Amazing work, love the sound quality and the option to lock parameters.
I will be using this tool instead of BFXR from now on.

Awesome tool, thank you <3

This is cool I really like it. What is the license on the tool and the sounds created with it?

Thanks! You have full ownership over any sounds you produce using the tool

Fantastic! I look forward to using this for games. Thank you.

I can't seem to play any sounds from within the editor; if I export them they play fine.  Running linux, but this also happens running the windows version under wine.


What did you use to create this program?

I second this question. I'm curious as to how it's only 114kb.


The program is written in C; it uses tigr, sokol_audio and microui.

Very cool! Thanks for listing the libraries that you've used! Really generous of you!

This... is... incredible... Compare it to electron or unity apps...


Thank you rxi! Any chance in releasing a macOS version?

Unfortunately not -- I don't own a mac myself which makes developing for it a bit of a problem

No worries, I understand. Thank you very much for this tool!

Well, let me know if you want help in that sense. I'm a software engineer (10+ yrs), I own a mac, and I'm right now in the rare situation of having some free time for a pet project.

Maybe a Hackintosh in a VM ;)?
