Audio formats differ in compression, quality, metadata, channel support and compatibility with players and editing software.
What to know about ALAC
Audio encoding
ALAC uses format-specific rules to store or compress sound.
Quality and size
Bit rate, sample rate, bit depth and compression influence both fidelity and file size.
Metadata
Track titles, artists, artwork and other tags may be supported depending on the format.
Compatibility
Support for ALAC varies across browsers, devices, editors and media players.
How ALAC conversion works
Converting ALAC decodes the source audio and encodes it with the destination format's codec and selected quality settings.
Lossy conversion cannot restore detail already removed from the source, so keep the original when quality matters.
mp3.now accepts ALAC as input and can also create ALAC output.
ALAC compatibility and software support
Check that the target player or editing application supports ALAC before choosing it for delivery.
MP3 remains a practical fallback when broad playback compatibility is the priority.
