Extract Audio from Blu-ray Disc

Have a concert recording or background music on a Blu-ray disc and wish to extract the audio from it so that you can play the music on your devices but haven’t any idea where to start. The following article will show you what types of audio you can save from Blu-ray disc and how to use the right Blu-ray audio extractor to complete the job effortlessly.

Blu-ray disc audio formats

Blu-ray disc provides much better sound quality than DVD disc by offering lossless audio formats including PCM, Dolby TrueHD or DTS-HD Master Audio soundtrack. These higher-resolution formats allow for up to 7.1 channels of uncompressed audio.


PCM, short for Pulse Code Modulation, is also called LPCM, Linear PCM, or Uncompressed. It encodes the original master without any compression. Therefore, it takes up large amount of Blu-ray disc space. However, it carries three fronts, four surround and a low frequency effect channel at higher sampling rates and bit depth.

Dolby TrueHD

Compared to PCM, Dolby TrueHD provides the same quality but takes less space in Blu-ray disc. Unlike PCM’s constant bit rate, it is a variable bit rate codec, which provides 8 full range channels 24-bit/96 kHz audio. Dolby TrueHD is the mandatory audio codec of HD DVD. Although most Blu-ray discs will encode audio with this codec, it’s becoming less popular these days than DTS-HD Master Audio.

DTS-HD Master Audio

Like Dolby TrueHD, DTS-HD takes up less space on a Blu-ray disc than uncompressed PCM. DTS-HD consists of two streams: one high resolution but lossy DTS track and one DTS-HD Master Audio track which is lossless. Because DTS-HD Master Audio requires more to be processed, it usually appears in high end of Blu-ray players. If you have a separate sound system, you could choose the corresponding Blu-ray disc with DTS-HD Master Audio. Otherwise, the DTS-HD Master Audio will be possibly converted to PCM or just digital Dolby before sending to the receiver.

Apart from above listed high quality lossless audio formats that included in original Blu-ray disc, sometimes, you may also wish to save Blu-ray disc to other audio format types such as WMA, MP3, AAC, FLAC, ALAC, M4A, etc for viewing on specific music playback devices. Then you may need a powerful Blu-ray Audio Converter application that offers more output audio options for you.
