FFSampledSP is a free implementation of the javax.sound.sampled.spi interfaces. It is part of the SampledSP collection of javax.sound.sampled libraries. Its main purpose is to decode audio from various formats at high speed using FFmpeg. To do so, it uses the tagtraum FFmpeg package, which offers FFmpeg binaries configured to decode audio while avoiding CODECs with patent problems. In other words, it supports formats like Ogg and FLAC well, while leaving MPEG-4 and MP3 unsupported.
