MKV to AIF: Extract Audio from MKV(Matroska Video) Video to AIF(AIFF/AIFC Apple Audio) with River Past Audio Converter, MKV2AIF 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 AIF?

Short for Audio Interchange File Format, a common format for storing and transmitting sampled sound. The format was developed by Apple Computer and is the standard audio format for Macintosh computers. It is also used by Silicon Graphics Incorporated (SGI).

The AIFF format is uncompressed so AIFF files tend to be large. However, there is another format called AIFF-Compressed (AIFF-C or AIFC) that supports compression ratios as high as 6:1.

AIFF files generally end with an .AIF or .IEF extension.

AIFC files generally end with an .AIFC extension.

AIFF and AIFC are standard audio format used on MacOS systems. AIFF is not compressed. AIFC is compressed.

To encode AIF audio, please make sure Apple QuickTime is installed.

Troubleshoot

If you don't see the AIF output option, you have a problem with your QuickTime installation.

You need to have the latest QuickTime installed. Occasionally, QuickTime may be corrupted. In any case, reinstall QuickTime should fix this problem.

You can change the compressor, and depending on the compressor, you can change the sample rate, channel (stereo or mono), bits/sample, and bitrate.

When "16 bit LPCM" or "16 bit PCM" is selected as the "Compressor", the file is uncompressed, and satisfy the original AIFF specification. When other compressors are used, the file is compressed and is considered to be an AIFC file.
