What is MQA?

MQA, or Master Quality Authenticated, is an audio format designed for the digital age. It was developed with the goal of preserving the sound quality of the original studio recording while optimizing it for streaming or downloading. MQA achieves this through a process known as ‘audio origami,’ where high-resolution audio files are ‘folded’ across the sound spectrum into smaller, more manageable file sizes. This allows for the efficient distribution of high-quality audio over the internet. MQA is a proprietary format.

One of the claimed features of MQA is its ability to ensure that listeners hear the audio exactly as the artists and producers intended. It's so-called lossless audio capability.

Despite its benefits, MQA has been a subject of debate among audiophiles. Some praise its ability to deliver high-fidelity sound in a compact format, while others question its advantages over other lossless audio codecs like FLAC. MQA's adoption by streaming services, most notably Tidal, has made it more accessible to the public, but it also requires compatible playback devices to fully experience its enhanced audio quality.

In fact, MQA provides true lossless audio only for 17-bit / 96 kHz resolution. However, FLAC is a serious competitor in terms of file size. [?]

In summary, MQA is a modern audio format that offers high-resolution sound quality with the convenience of smaller file sizes, making it a compelling choice for those seeking the ultimate listening experience in the digital era. However, its reception and widespread adoption remain mixed, as the audio community continues to discuss its place in the landscape of high-quality music formats.

What is FLAC?

FLAC stands for Free Lossless Audio Codec, an audio format that has gained widespread popularity among music lovers and audiophiles. It is an open-source codec which means it is available for anyone to use without licensing fees. The 'true lossless' aspect of FLAC is its most significant feature; it compresses audio files without any loss of quality, ensuring that the sound remains identical to the original source.

The main advantage of FLAC over other formats is its ability to reduce file sizes significantly while maintaining perfect audio fidelity. This makes it an ideal choice for those who don't want to compromise on sound quality but also wish to save storage space. Unlike MP3s or AACs, which lose some audio information to achieve smaller sizes, FLAC keeps all the data intact.

FLAC's compatibility with a wide range of devices and software makes it a versatile choice for many users. Whether you're listening on a smartphone, computer, or high-end audio system, FLAC files can deliver high-quality sound across platforms. Additionally, FLAC supports high-resolution audio, which can go beyond CD quality, providing an even richer listening experience.

In summary, FLAC is a robust audio format that offers lossless compression, ensuring that listeners can enjoy music that is true to the original recording. Its open-source nature and compatibility with various devices further cement its position as a preferred choice for high-quality audio.

MQA vs FLAC Comparison

When evaluating MQA (Master Quality Authenticated) and FLAC (Free Lossless Audio Codec), several key criteria come into play. These factors are crucial for understanding the differences between the two formats and determining which might be the best fit for your audio needs.


Sound Quality

The primary concern for most audiophiles is sound quality. MQA claims to deliver the sound of the original studio master with a smaller file size. FLAC is known for its lossless audio quality that is true to the original recording. The debate often centers on whether the "folding" technique used by MQA actually preserves the nuances of the master recording. Alternatively, some argue that FLAC's straightforward lossless compression offers a more authentic sound.
Above, we considered that MQA may be truly lossless for 17-bit / 96 kHz resolution only. FLAC is truly lossless format for any of its supported resolutions.
Master Quality Authenticated format promises some enhancement on high resolutions after the "unfolding", but not every listener wants it.


File Size

File size is another important consideration, especially for those with limited storage space or bandwidth. MQA's "audio origami" allows for high-resolution audio in a file size that's often smaller than traditional FLAC files. However, FLAC remains a popular choice for efficiently storing truly lossless audio without the need for proprietary technology or software.


Compatibility and Availability

Compatibility with playback devices and software is essential for a hassle-free listening experience. FLAC enjoys widespread support due to its open-source nature, making it playable on a variety of devices and platforms.
