The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Each card starts with one representative test file. Choose a use case, search, or filter to find a specific profile; a card’s variant menu contains its related samples.

Sample Rate Ladder
A 1 kHz sine tone sampled at 16000 Hz: part of a sample-rate ladder (8/16/44.1/48/96 kHz) of the identical tone, for testing resampling, sample-rate detection, and aliasing.
Color And Metadata
A 16-bit (deep-colour) grayscale PNG holding a smooth 0–65535 gradient, for testing high-bit-depth support and spotting banding when a tool truncates to 8-bit.
3gp
The clip as 3GP: the 3GPP mobile container from the feature-phone era. For testing 3GP demuxing and conversion.
Mesh
A 10 mm cube as 3MF: the modern OPC-packaged manufacturing format (a ZIP of model XML plus relationships). For testing 3MF readers and slicers.
Bit Depth Ladder
A 440 Hz sine tone stored as 16-bit PCM: part of a bit-depth ladder (8/16/24-bit) of the identical tone, for testing bit-depth conversion, dithering, and quantisation-noise handling.
Formats
A 60 frames-per-second clip with a smoothly sweeping marker: double the usual frame rate. A fixture for testing high-frame-rate playback, frame-rate detection, and fps conversion (60→30 decimation).
Sevenzip
A 7-Zip archive using LZMA2 compression, containing a small documented file tree. For testing 7z extraction and conversion.
Sevenzip
A password-protected 7z archive (AES-256, encrypted header). The password is “novus-example”, printed here on purpose so you can test encrypted-archive extraction. Contains only harmless sample text.
Hdr Linear
8-bit PNG twin of the linear 16-bit greyscale ramp. Compare banding after truncation.
Sync
A five-second clip that flashes white and plays a 1 kHz beep on every whole second: the first clip in the library WITH an audio track. A direct fixture for measuring and correcting audio/video sync (lip-sync) offset.
Codec Set
The clip as raw AAC in an ADTS stream: the codec behind most streaming and mobile audio. For testing AAC decoders and remux into MP4.
Container Formats
A pure 1 kHz sine tone stored as AIFF: Apple's big-endian 16-bit PCM container, 3 seconds, 44.1 kHz mono. A clean reference for testing AIFF decoders and WAV↔AIFF conversion.
Container Formats
A pure 440 Hz sine tone stored as AIFF: Apple's big-endian 16-bit PCM container, 3 seconds, 44.1 kHz mono. A clean reference for testing AIFF decoders and WAV↔AIFF conversion.
Airflow
An Airflow DAG definition in the classic operator style, using only the no-op EmptyOperator so the file describes a topology and performs no work. Carries the six-task ETL graph shared across the Airflow JSON, Argo, Grap
Airflow
A decorator-based Airflow TaskFlow DAG where dependencies are implied by function calls rather than >> operators: the shape static DAG extractors most often get wrong. Every task returns a literal, so nothing performs I/

ANSI X12 810 invoice with a wrong SE segment count for Alder Table Bistro. Identical to edi-810-invoice.edi except for one element: SE declares 11 segments where 13 are present between ST and SE inclusive. The ISA, GS, G
