What is a .flac file?
FLAC (Free Lossless Audio Codec) compresses PCM audio losslessly, typically to about half the size of the original with no quality loss. It supports metadata tags, embedded cover art, and fast seeking. It is favored for archival and audiophile music libraries.
How to use this file
Use an example FLAC to test lossless decoding, verify bit-exact round-trips against source PCM, and exercise tag parsing and transcoding to lossy formats.
How to use this file for testing
“FLAC with Vorbis Comments and Picture” is a deterministic Novus Examples fixture for Metadata testing, Conversion testing. Images, audio, video, and documents with documented metadata paired with deliberately stripped versions, for verifying extraction, preservation, redaction, and privacy-scrubbing behavior.
Documented properties for this file: FLAC · 96,878 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Media fixtures are short and synthetic by design. Prefer waveform or transcript ground truth in the same group when measuring ASR, trim, upscale, or sync tools; do not assume broadcast-quality masters.
