| Property | Value | Why it’s relevant | |----------|-------|-------------------| | | speechdft-16-8-mono-5secs.wav | Self‑descriptive: “speech DFT”, 16 kHz sampling, 8‑bit depth, mono, 5 s long. | | Length | 5 seconds | Short enough to fit comfortably in a Jupyter cell, long enough to contain a few spoken words or a short phrase. | | Sample Rate | 16 kHz | Common in telephony & low‑latency speech‑recognition models. Provides a Nyquist limit of 8 kHz, covering the bulk of human speech intelligibility. | | Bit Depth | 8‑bit (PCM) | Introduces quantisation noise—great for testing robustness of algorithms that must handle low‑quality audio (e.g., IoT devices). | | Channels | Mono | Simplifies processing (no need to worry about left/right mixing). | | Content | Human speech (likely a single speaker, neutral tone) | Perfect for speech‑feature extraction (MFCC, LPC, pitch tracking) and for visualising the effects of DFT on real‑world audio. |
