MKV to MPA: Extract Audio from MKV(Matroska Video) Video to MPA(MPEG Audio) with River Past Audio Converter, MKV2MPA converter, conversion

What is MKV?

Matroska aims to become THE standard of multimedia container formats. It was derived from a project called MCF, but differentiates from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers.

It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in conception to other containers like AVI, MP4 or ASF, but is completely open source. Matroska file types are .MKV for video (and audio) and .MKA for audio-only files.

To convert MKV files to other video formats, please have CCCP installed.

What is MPA?

There are three "layers" in the MPEG-1 Audio specification.

In MPEG Audio Layer-1, a simple 32-subband audio compressor using a floating point representation for subband samples. Resolution and scale factor are stored for groups of 12 subsamples. MP1 is only used for Philips DCC Digital Compact cassette with data rates of 384 kbps.

Both MPEG-1 and MPEG-2 files use MPEG-1 Audio Layer-2.

MPEG-1 Audio Layer-3 becomes the widely popular MP3.

MPEG.ORG is an excellent source for additional information on MPEG format and usage.

To encode MPEG Audio, you will need River Past MPEG-2 Booster Pack in addition to your audio software.
