What is the best player for FLAC audio?

What is FLAC Audio?

FLAC (Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio. Lossless compression means that when an audio file is compressed using FLAC, it can be decompressed into an identical copy of the original audio data. No information is lost during compression.

FLAC uses linear prediction to compress audio data. This allows it to compress audio data by 30-50% without any loss in quality. When compressed with FLAC, the WAV file of an audio track will be roughly half the original size without any information loss. This makes FLAC beneficial for archiving audio and reducing bandwidth needed for streaming and downloading large audio files.

The key advantage of FLAC over lossy formats such as MP3 is that it preserves the full quality of the original audio. Lossy compression formats like MP3 work by discarding audio data that is considered beyond the auditory resolution ability of most people. While lossy formats take up less space, the discarded data results in degraded sound quality. FLAC allows original CD-quality audio to be compressed without this quality loss.

According to the Internet Engineering Task Force (IETF) Cellar Working Group, “The full encapsulation definition of FLAC audio in MP4 files was deemed too extensive to include in this document. A definition document can be found at https://github.com/cellar-wg/Cellar-FLAC/blob/master/flac.md“

Why Listen to FLAC?

FLAC (Free Lossless Audio Codec) offers better sound quality than lossy formats like MP3, AAC, and OGG by preserving all the original audio information. While lossy formats use “perceptual coding” to selectively discard audio data that is considered beyond the auditory resolution ability of most listeners, FLAC retains everything in the original uncompressed audio (source).

This makes FLAC files useful for audiophiles who want the highest fidelity playback, as well as recording engineers and other audio professionals who need access to the raw, uncompressed audio data for editing and archiving. The ability to retain the integrity of the original studio master recordings gives FLAC an advantage over lossy formats when listening with high-end audio gear or critical ears.

However, FLAC’s preservation of original audio information comes at the cost of larger file sizes compared to lossy formats. While this may be an acceptable trade-off for sound quality for some, others may prefer the smaller files of lossy audio for portability or storage reasons. Still, for critical listening applications where audio quality is paramount, FLAC reigns supreme.

Flac Hardware Players

For dedicated audiophiles, using a hardware player designed specifically for high-quality FLAC playback can provide advantages over relying solely on software players. There are several brands that produce premium portable players with support for FLAC files and high-end audio components like external DACs (digital-to-analog converters).

Some well-known options include:

FiiO – Budget-friendly brand with models like the M11 that offer excellent value.
Astell&Kern – High-end luxury brand with gorgeous designs and premium build quality.
Sony – Reliable brand with mid-range models like the NW-A55 that focus on usability.

HiBy – Emerging audiophile brand with powerful processor chips optimized for audio.

The main benefits of using a dedicated FLAC hardware player are the optimized audio circuitry and components that are designed specifically for music playback, not just as an added feature. This can lead to lower noise, less distortion, more power output, and higher sound quality compared to listening via a smartphone or computer.

Additionally, high-end models boast premium DAC chips, balanced outputs, and support for formats like native DSD. The user interface is also tailored for music listening versus generic mobile device usage. On the other hand, hardware players are more expensive, less versatile, and need to be charged separately from your phone.

Ultimately, a FLAC hardware player is best suited for discerning listeners who are willing to pay more for premium audio quality on the go when listening to lossless music files. For most budgets and casual listening, a software player on a phone or computer will be sufficient.

Recommended FLAC Settings

When ripping audio CDs to FLAC, it’s generally recommended to use the following optimal encoding settings for the best quality:

Sample Rate: 44.1 kHz or 48 kHz – These are the two most common sample rates used on audio CDs. There is debate over which is better, but both will provide high quality results.¹

Bit Depth: 16 bit – This matches the bit depth of audio CDs. Higher bit depths like 24 bit are not necessary.²

Compression Level: 5 or 8 – FLAC is lossless at all compression levels, but 5-8 provides a good balance of file size reduction while still being relatively fast to encode.³

Metadata Tagging: Accurately fill out all relevant ID3 tags, including title, artist, album, track number, genre, etc. This helps organize music libraries and provide info to players.

In summary, ripping CDs to FLAC with 44.1kHz or 48kHz sampling, 16 bit depth, compression level 5-8, and comprehensive metadata provides excellent quality in an efficient package.

Conclusion

In summary, FLAC (Free Lossless Audio Codec) is an excellent uncompressed audio format that provides CD-quality audio in compressed file sizes. Though FLAC files are larger than popular lossy formats like MP3, the audio quality is vastly superior as no data is lost in compression.

For those seeking the very best audio quality, VLC Media Player and Audirvana are two of the top options for desktop FLAC playback thanks to their focus on bit-perfect output. Foobar2000 offers incredible customization and tweaking for those who want more fine-grained control. Roon provides a beautiful interface and robust metadata support ideal for large libraries. On mobile, UAPP and Poweramp are standout Android choices while Vox is great on iOS.

There are many legal sources for FLAC files such as HDtracks, Tidal, and Bandcamp. With the right player, listeners can experience their favorite music in the highest fidelity possible.
