What is a 10MB FLAC file useful for?

A 10 MB FLAC file provides approximately 4 minutes of lossless audio — a full music track or a long field recording segment. Use it to test the full lossless audio processing pipeline: FLAC upload, archival storage with integrity verification (MD5 checksum from STREAMINFO), FLAC-to-AAC transcoding for streaming, and waveform image generation. At 4 minutes it is long enough to test seek accuracy in lossless audio players.

What's inside this file?

Generated by ffmpeg. A 440 Hz sine tone approximately 4 minutes long at 44.1 kHz, 16-bit, stereo. The equivalent uncompressed WAV would be approximately 80 MB. FLAC's STREAMINFO block stores the MD5 hash of the uncompressed PCM data — any corruption during upload or storage is detectable by re-decoding and comparing the MD5.
