What is FLAC?

FLAC (Free Lossless Audio Codec) provides lossless compression of digital audio without any quality loss, reducing file size by 50-60%.

What is M4R?

iPhone Ringtone (M4R) is Apple's ringtone format based on AAC audio, used for custom ringtones on iPhones.

When Should You Use FLAC vs M4R?

FLAC vs M4R: Key Differences

• •FLAC and M4R diverge on compression: lossless compression for the source, lossy compression for the target.
• •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
• •Alpha channel support: M4R lacks transparency support, so semi-transparent pixels from the source will be lost.
• •Storage footprint: 5MB per minute at CD quality for FLAC vs Very small, under 500KB for M4R.
• •Use case fit: FLAC targets archival audio, audiophile listening and M4R targets iphone ringtones, notification sounds — your choice depends on which workflow stage you are serving.
