Compiling miniaudio without any external dependencies

[ell1e]

I am writing a program where I want to support a headless environment (= no desktop libraries, including no audio libraries and no graphics libraries). However, I am looking for a decent baseline audio resampler.

Is it possible to compile miniaudio somehow in a way that never accesses, links, loads any sort of system or sound library other than the C API while still offering access to the resampler? Like miniz for example offers #define MINIZ_NO_STDIO to get the pure compression functionality in memory without touching any file input or output.

There's a suite of defines you can use to eliminate parts of the code, but the main one you're after is probably #define MA_NO_DEVICE_IO which will need to be visible to both the the header and implementation section. Section 2.7 in the documentation will give you additional options.

However, if you're looking at miniaudio just for resampling, you might actually want to consider looking elsewhere for that. The miniaudio resampler is just a simple linear resampler with a low-pass filter for anti-aliasing (the LPF stuff can be configured). I make no claims on it being particularly good quality or fast.

That's so cool, looks like MA_NO_DEVICE_IO is what I'm looking for! Thanks 😊 I'm really not looking for anything else than a resampler, for now.

I wonder, would you have any recommendations for any good baseline resamplers? I know there are better resamples, but I couldn't really find any that are available as a single header. I know libsrc is the de facto standard, but it's just kind of a big dependency that I don't want to ship as part of the core base set. (I might add optional support or it later at some point.)

r8brain was my pick when I last looked around. High quality, performant, easy api, and seems very thoughtfully designed

Oh although it’s technically not header only, you do need to include a cpp file in your build

My project is C only, sadly! But I hope this will help someone else coming by from a web search for this topic in the future 😊

Ah, sorry I missed that, you mentioned the C API in your discussion post. Good luck!
