This class is not used elsewhere, please make it private.
Additionally, the fields in this class should not be declared public as they are not effectively accessible outside this class.
Either make them private, or of you prefer a more compact look, make them package-private (by just omitting public).

Indentation is off in various places in this class. Please either use 4 spaces or 1 tab for indentation, and don't mix both styles.

This condition will always evaluate to true (ctx.format is only written in line 51 and checked immediately after)
WAV PCM audio is such a simple and safe format. RIFF format is supported so why not WAV files?
