**TLDR:** A time-frequency representation that maps audio into a frequency scale closer to human auditory perception.

<p>The mel spectrogram is one of the most widely used intermediate representations in modern speech and audio AI systems. It maps raw waveforms into a more learnable and acoustically meaningful surface. A wide range of tasks, including ASR, TTS, emotion analysis, and audio classification, are built on top of this representation. It offers a practical balance between temporal and frequency information.</p>
