DTMF Dialing Tones (WAV)
A DTMF (touch-tone) dialing sequence dialing a reserved 555-01xx number — each digit is the standard dual-tone pair. A fixture for testing DTMF decoders, Goertzel detectors, and tone analysis.

What is a .wav file?
WAV (Waveform Audio) is a RIFF-based container that typically holds uncompressed linear PCM audio, though it can wrap other codecs. Because samples are stored raw, files are large but lossless and simple to read, with configurable sample rate, bit depth, and channel count. It is the standard format for high-fidelity and intermediate audio.
How to use this file
Use an example WAV to test PCM decoding, sample-rate and bit-depth handling, waveform rendering, and audio pipelines that need a lossless reference source.
How to use this file for testing
“DTMF Dialing Tones (WAV)” is a deterministic Novus Examples fixture for Audio analysis. Pure tones, sweeps, and noise with known frequencies and levels for testing spectrum, level, and waveform tools.
Documented properties for this file: 16-bit · 1 ch. 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.
