**TLDR:** A core transform that enables windowed analysis of audio frequency content over time.

<p>The Short-Time Fourier Transform is one of the most fundamental mathematical tools in modern audio processing. A raw waveform is analyzed in the frequency domain through small time windows, producing spectrogram-like representations. This makes it indispensable for understanding audio jointly in time and frequency. It is a shared foundation across speech, music, and general audio analytics systems.</p>
