## PortAudio Binding for the Ada Programming Language

This is a thick binding of [PortAudio](https://www.portaudio.com/). So effort
has been made to get rid of all C-isms and C-specific types wherever possible.
In particular:

<ul>
  <li>Pa_Initialize and Pa_Terminate are now automatic</li>
  <li>All error codes have been converted to exceptions</li>
  <li>Void pointers are completely absent</li>
  <li>Standard error is suppressed in C during init, so no unexpected text
  output</li>
</ul>

The package hierarchy is as follows:

<ul>
  <li>Portaudio (Version information, exceptions, and a few common minor types)
    <ul>
      <li>Portaudio.Devices (Host_API and device related things)</li>
      <li>Portaudio.Streams (Streams, sample buffers, and callbacks)</li>
    </ul>
  </li>
</ul>

A few short example programs are available in the `example` subdirectory.

#### Building and Installation

This repository is written to use the GNAT Project Manager build tools. To
build, use the following command

`gprbuild portaudio.gpr`

There is a single build switch of `-Xbuild` which can have a value of `release`
(the default) or `debug`.

To install the binding, use

`gprinstall -p -m portaudio.gpr`

The other gpr file `example.gpr` can be used to build the short example
programs provided.

For further information on the build tools, consult the
[GPRbuild docs](https://docs.adacore.com/gprbuild-docs/html/gprbuild_ug.html).



#### Credits and Licensing

This binding and the Ada test/example programs were written by Jedidiah Barber.

All code of this binding and example programs is released into the public
domain. Consult `unlicense.txt` for further information.
