A test framework to playback various audio formats using only features of Qt plus format specific libraries.

It consists of a couple of components: sources, sinks, scanner, decoder and player.

Audio sources are QIODevice based so they can be read and written to like any Qt IO source.

Currently implemented are:

• libsidplayfp for SID files
• libopenmtp for Tracker modules (Prefered!)
• (libmodplug for Tracker modules (Optional, deprecated))
• libasap for SAP files
• sc68 for Atari and Amiga SC68 and sndh files
• FLAC

Basic usage of source goes like this:

• The source file data is loaded normally into a buffer, say a QByteArray
• source is opened for writing and the data is written to it
• source is closed
• source is opened for reading
• source is assigned to a sink, for example a QAudioOutput
• playback!

Currently work in progress, test app is using QAudioOutput

• Qt QAudioOutput
• ALSA
• QNX QSA
• Raw data file writer
• WAV file writer

Media file scanner, for now using only file extensions to decide what source to use.

Helper to check what source to use. Works.

To make playback easy as:

• load();
• play/stop/pause();

Works.

Support is planned for more formats:

• uade module playback
• other retro formats
• ogg, etc

I started working on a retro music player for BB10 devcies. The coded started as a very simple test on using libplayfp and QNX QSA audio output. Then it grew. And became a messy tangle of stuff bolted on and adding new formats and features started to be way too complicated.

So I started to create a simple framework for playback of various retro formats that works on plain Qt / QNX / BlackBerry 10.
