What is it?

FLAC (Free Lossless Audio Codec) ist ein Open-Source-Audioformat, das Audio ohne Qualitätsverlust komprimiert und die genauen ursprünglichen Audiodaten bewahrt, während die Dateigröße im Vergleich zu unkomprimiertem WAV um 40-60% reduziert wird.

Das Verständnis von FLAC hilft Ihnen, das richtige Format für Ihre spezifischen Bedürfnisse und Arbeitsabläufe auszuwählen.

Pros & Cons

Advantages

Perfect Quality

Decoding a FLAC file produces bit-for-bit identical audio to the original - no quality loss whatsoever.

Smaller than WAV

FLAC compresses audio by 40-60% without any quality loss, saving significant storage compared to WAV or AIFF.

Open Source

FLAC is completely free and open-source with no licensing fees or patent restrictions.

Excellent Metadata

Supports comprehensive tags for artist, album, artwork, lyrics, and ReplayGain data.

Disadvantages

Larger than MP3

FLAC files are typically 3-5x larger than equivalent MP3 files, using significantly more storage.

Limited Streaming

Most music streaming services use lossy formats. Only Tidal and Qobuz offer FLAC streaming.

No iTunes Native Support

Apple iTunes and iOS do not support FLAC natively; you need to convert to ALAC for Apple devices.

CPU Intensive

Decoding high-resolution FLAC files requires more processing power than MP3 on older hardware.

When to Use It

Hier sind die häufigsten Szenarien, in denen FLAC die richtige Wahl ist:

Music Archiving

Audiophiles and music collectors use FLAC to rip CDs with perfect quality preservation.

Hi-Res Music

High-resolution audio (24-bit/96kHz or higher) is distributed in FLAC for audiophile listening.

Recording Masters

Musicians and producers store master recordings in FLAC before converting to lossy formats for distribution.

Frequently Asked Questions

Can you hear the difference between FLAC and MP3?

For most people in normal listening conditions, no. The difference is audible only on high-end audio equipment with trained ears.

Is FLAC worth the larger file size?

If storage is not a concern and you have quality audio equipment, yes. For casual listening on earbuds, high-quality MP3 is sufficient.

Can iPhone play FLAC?

Not natively. iOS does not support FLAC. Use VLC app, or convert to ALAC (Apple Lossless) for native iPhone playback.

How do I convert CD to FLAC?

Use EAC (Exact Audio Copy) or dBpoweramp for accurate CD ripping to FLAC. These tools verify data integrity during ripping.

What is the difference between FLAC and ALAC?

Both are lossless. FLAC is open-source and widely compatible; ALAC (Apple Lossless) is Apple's equivalent used in iTunes and iOS.
