# audio-utsl

A C audio player library you can build from source!

Integrates libsndfile with portaudio.

This project is intended to fill the same niche that

[BASS](https://www.un4seen.com/bass.html) does.  BASS is

awesome, but I couldn't get it to run recently, possibly because of

a false positive on the AV scan.  This project doesn't require any binary

blobs.

## Installation

 - Install libsndfile, portaudio, and pthreads.  E.g., on cygwin, those are

   packages you can install from setup.exe.

 - `make`.  This will build the three examples.

## Usage

To use audio-utsl in your own projects, just copy everything in `src` to

some directory in your project and make sure that directory is listed as `-I`.

See the example `CFLAGS` and `LDFLAGS` in [Makefile](Makefile).

## Internals

 - A producer thread to read from the source using libsndfile

 - A portaudio callback consumer (which probably runs in portaudio's own thread)

   to pass the data to portaudio

 - [PortAudio's ring buffer](https://app.assembla.com/spaces/portaudio/git/source/master/src/common/pa_ringbuffer.h)

   to pass ownership of blocks of data between the producer and the consumer
