| File | Format | Size | What it catches |
declared-length-mismatch.wav | WAV | 172 KB | Valid WAV whose data chunk header declares ten times more bytes than the file actually contains. |
no-id3-raw.mp3 | MP3 | 31.4 KB | The same audio with no ID3 tag at all, so the file begins directly with an MPEG sync word. |
silence-30s.wav | WAV | 2.5 MB | 30 seconds of digital silence, 16-bit PCM mono. |
silence-5s.mp3 | MP3 | 77.9 KB | Five seconds of silence as MPEG-1 Layer III, 128 kbps, 44.1 kHz mono, with an ID3v2.3 tag carrying a title and artist. |
tone-5s.wav | WAV | 431 KB | 5 seconds of a 440 Hz sine tone, 16-bit PCM mono at 44.1 kHz. |
truncated-header.wav | WAV | 30 bytes | A WAV file cut off after 30 bytes, mid-header. |
very-short-10ms.wav | WAV | 926 bytes | 10 milliseconds of audio - 441 samples. |
empty-ftyp-only.mp4 | MP4 | 28 bytes | A valid ftyp box declaring isom/mp42 branding, with no moov and no mdat - structurally an MP4, but with zero tracks. |
fake-mp4-wrong-magic.mp4 | MP4 (spoofed) | 64.0 KB | Named .mp4 but the first bytes are random noise rather than an ftyp box. Contains no video data. |
