What is a MPC file?
A file with .mpc extension is a Musepack audio file format that uses audio compression with a strong emphasis on high quality. This makes it possible for you to not even notice the sound quality differences of original WAV file and the compressed MPC file. It uses MPEG-1 Layer-2 algorithms to achieve highly optimized compression. Musepack MPC file format is open source with BSD/GNU LGPL license. The SVN repository by Musepack allows to get latest updated code for the codec. Applications that can open MPC files include VLC Media Player, JetAudio, and Winamp in addition to several others.
MPC File Format
MPC file uses the MPEG-1 Layer-2 algorithms to compress the audio files. It is a container-independent format and also allows raw stream encoding. The format doesn’t use any internal clipping and is streamable with sample-accurate cutting. Its Packetized stream allows multiplexing into audio and video containers such as MKV.
Key Characteristics of MPC Files
| Characteristic | Description |
|---|---|
| Audiophile-Centric Design | The entire development philosophy is geared towards achieving the highest possible perceptual audio quality, not maximum compression. |
| Open-Source and Royalty-Free | MPC is an open-source project, meaning it is free to use, modify, and distribute without any licensing fees or patent restrictions. |
| Niche but Dedicated Community | While not mainstream, it maintains a loyal following among audio enthusiasts who value its transparent sound quality. |
| Limited Hardware Support | Unlike ubiquitous formats like MP3, native support for MPC in consumer devices like car stereos or portable players is rare. Playback is typically guaranteed on PCs using supported software. |
| File Extension | MPC files are most commonly saved with the .mpc extension, but you may also encounter the older .mp+ extension. |
FAQ
Q1: Is MPC better quality than MP3?
A: Yes, at comparable bit rates, MPC generally provides superior audio quality, especially in preserving high-frequency detail and complex musical textures.
Q2: What software can play MPC files?
A: Most advanced media players like VLC, Foobar2000, and Winamp support MPC natively through their built-in codec libraries.
Q3: Is MPC a lossless format like FLAC?
A: No, MPC is a lossy format; it discards data to reduce file size, but it is designed to be perceptually lossless for most listeners at high bit rates.
Q4: Why isn’t MPC as popular as MP3?
A: MP3’s first-mover advantage, massive marketing, and wider early adoption in hardware devices created a standard that was “good enough” for the general public.
Q5: Should I use MPC for archiving my music?
A: For a perfect archive, a true lossless format like FLAC is recommended. However, for a high-quality, space-saving archive where transparency is the goal, MPC is an excellent lossy choice.
