Quick Verdict
Use TTA when…
Use TTA only if you specifically need it for a tool or workflow that requires it. TTA's compression is very slightly better than FLAC's default settings, but the ecosystem difference is enormous.
Use FLAC when…
Use FLAC for all lossless archiving. FLAC is supported on virtually every platform, player, and streaming service that supports lossless audio. Choose FLAC unless you have a compelling reason not to.

Frequently asked questions
Is TTA audio quality better than FLAC?
No — both are lossless. The decoded audio is bit-perfect from either format. TTA achieves slightly smaller file sizes than FLAC at its default compression level, but FLAC at level 8 or 12 can match or beat TTA.
How do I convert TTA to FLAC?
`ffmpeg -i input.tta -c:a flac output.flac`. This is a lossless conversion — the audio samples are identical in both files. Metadata is preserved.
