Convert TrueHD 7.1 MKV files to WMV keeping the TrueHD audio track


Dolby TrueHD audio is one of the two best surround sound formats found in today’s Blu-ray-based home theater systems. This lossless surround format is identical to the sound heard at the theater and comes across best via HDMI connection from Blu-ray players. Dolby TrueHD is a lossless audio format, which means there is no fidelity lost when encoded onto Blu-ray. A Dolby TrueHD bitstream can carry up to 16 discrete audio channels. Sample depths up to 24 bits/sample and audio sample rates up to 192 kHz are supported. Like the more common legacy codec Dolby Digital, Dolby TrueHD bitstreams carry program metadata. Metadata is separate from the coding format and compressed audio samples, but stores relevant information about the audio waveform and provides control over the decoding process.

Many people rip Blu-ray DVD into MKV files, so you will sometimes see Dolby TrueHD in MKV file. However, few of players support TrueHD format, you have to convert TrueHD audio MKV file into more popular format to play it anywhere.
