I found this: https://github.com/p0nce/dplug

Which seems to be a good analysis library but I haven't found a library to play sounds.
Is there one?

Downloaded it, put the D example in a source folder, downloaded the official library, compiled the official library, stuck the libportaudio.la with the example, ran DUB and it can't the port audio library.
Undefined symbols for architecture x86_64:
  "_Pa_CloseStream", referenced from:
      __Dmain in unknown.o

The source is 3 years old, probably why no dub.json file. Know how to fix the library problem?

What does dub -v show?

SDL2 can through DerelictSDL2 (use the mixer extension for easier playback).
D-SFML can probably too.


Out of Topic: we need what ae.utils.graphics does for images, but for sound! A good abstraction for audio data and processors would be welcome.
Vanilla ranges do not cut it since it would need the additional concept of:

- clearing the state (setting delaylines to 0)
- separate channels that can be stored interleaved or not. Samples would be indexed by time and channel index. I feel like samplerate can be left out of the equation, it will almost always be a runtime value.

- and more importantly, batch processing instead of sample per
sample like I do now in dplug

in d plug sample by sample processing is justified because of the z-transform, while in video games you just basically play some wavetables.

I've seriously considered in the past to implement a library just like Devisualization.Window but for sound. Unfortunately my knowledge of sound/music isn't good enough to do so.

idk if it would be useful at all, I'm not even happy with it myself yet, but I am writing a simpleaudio.d https://github.com/adamdruppe/arsd/blob/master/simpleaudio.d

it is meant to do waveform i/o and MIDI, but I'm not happy with my first draft of the api so it is probably going to change.... eventually.

Currently works on Windows (winMM) and Linux (ALSA).

It should work, I'm using it a lot. I use libportaudio.a, make sure you reference deimos/portaudio.di or have it in your `source` folder. Here's an excerpt from my dub.json (you might have to include other libs too):

"libs": [
        "portaudio",
        "asound",
        "jack",
        "sndfile",
        "FLAC",
        "vorbisenc",
        "vorbis",
        "ogg"
      ],

Also, compile or download the portaudio lib for x86_64, if you're on 64bit. Alternatively, compile your code with -m32.

BTW, did you pass the library to the compiler and linker?
