+|         OneLoneCoder Pixel Game Engine Extension            |
+|                    AudioListener v1.0                       |
++-------------------------------------------------------------+
+
+What is this?
+~~~~~~~~~~~~~
+This is an extension to the olcPixelGameEngine v2.16 and above.
+
+Its purpose is to allow audio integration into PGE which is
+compatible with Emscripten for Web applications also.
+
+Unlike my other extensions, this one requires some external
+libraries and additional setup (refer to github for instructions).
+
+In addition to the libraries the following files are required:
+
+olcPGEX_AudioListener.h      (this file)
+olcPGEX_AudioSource.h
+
+These can be found in the github repo as well...
+
+
+What it can do:
+~~~~~~~~~~~~~~~
+Play Audio!
+
+Using SDL2 as a backend and SoLoud as a frontend, this extension allows you
+to easily load and manipulate sound in a way that is cross platform and also
+has web support (using emscripten for PGE).
+
+In addition to the standard PLAY, PAUSE, and STOP controls you can also adjust
+VOLUME settings and MODULATION (playback speed).
+
+WAV and OGG are supported on most backends, however MP3 is also supported by
+SoLoud and SDL2 (even inside the web browser!).
+
+
+Limitations:
+~~~~~~~~~~~~
+Requires SDL2, SDL2_Mixer, and SoLoud libraries be installed and linked
+successfully (detailed instructions on the github repo).
+
+
+How Does It Work?
+~~~~~~~~~~~~~~~~~
+Once you have followed the setup instructions on the github repo and
+successfully compiled the test program you are ready to follow these
+instructions...
+
+Add the following defines / includes underneath your olcPixelGameEngine
+include:
+
+#define AUDIO_LISTENER_IMPLEMENTATION
+#include "olcPGEX_AudioListener.h"
+#define AUDIO_SOURCE_IMPLEMENTATION
+#include "olcPGEX_AudioSource.h"
+
+(Order matters here, they must be included exactly as above!)
+
+In your declarations add exactly (1) AudioListener
+
+olcPGEX_AudioListener AL{};
+
+
+(Note: Currently, only 1 instance of an AudioListener is permitted)
+
+Now add at least (1) AudioSource (you will eventually add many of these)
+
+olcPGEX_AudioSource AS_Test{};
+
+
+In the OnUserCreate function you must now initialise the AudioListener
+
+AL.AudioSystemInit();
+
+
+Next we can assign our AudioListener to our AudioSource and load an audio file
+
+AS_Test.AL = &game.AL;
+AS_Test.LoadAudioSample(1, "./assets/mus/Test.mp3");
+
+
+This assumes you have an MP3 file called "Test.mp3" in the listed folder in your
+project directory.  Also note the ID is set to "1" in this example. It is recommended
+that you assign labels to your audio files as IDs instead so you can more easily
+keep track of them. For example
+
+enum AUDIO
+{
+NULL_SND = 0, // used as a default case
+TEST_SND = 1,
+// add other sounds here
+};
+
+AS_Test.LoadAudioSample(TEST_SND, "./assets/mus/Test.mp3");
+
+This way you can easily refer to your sound without having to remember the integer
+value you assigned it in the beginning...
+
+
+Now all that is left to do is play the sound...
+
+In OnUserUpdate we can play / stop the sound using the SPACEBAR like so
+
+if (GetKey(olc::Key::SPACE).bPressed)
+{
+if (AS_Test.bIsPlaying)
+AS_Test.Stop();
+else
+AS_Test.Play();
+
+}
+
+
+Those are the basics... other features can be accessed in much the same way.
+
+Enjoy!

+A very bare bones emulator for Commodore VIC-20 sound chip. Supports both PAL and NTSC models.
+Bass, alto and soprano should be quite close to original vic, noise probably not so.
+
+The first three channels (bass, alto and soprano) are square waveform generators with 7-bit frequency.
+The highest bit of each oscillator register switches the oscillator on/off.
+The fourth oscillator generates a noise waveform.
+
+VIC-20 does not have per channel volume control, only global volume,
+which you can change by setting audio source's volume.
+
+To get that authentic moldy VIC-20 sound, the audio source should be coupled with a biquad resonant filter
+with the following params: type = LOWPASS, sample rate = 44100, frequency = 1500, resonance = 2.0.
