Foobar2000 plays most audio files but can be extended. There is an official Encoder Pack which is a good place to start.

www.foobar2000.org/encoderpack

After downloading the latest version of the encoder pack, launch the installer and confirm it’s found the correct foobar2000 installation.

The next step is to deselect any encoders you don’t need.

And then click Install

Installing Additional Encoders

You may also need to install additional encoders; these are installed as components. For instance, foo_midi.fb2k allows foobar to play midi files. The component’s download page is here:

www.foobar2000.org/components/view/foo_midi

After you’ve downloaded the component, double click it and foobar should start the component installation procedure.

Click Yes and foobar will install foo_midi and require a restart. Once this is done, you should confirm that foo_midi was installed.
