Concept | Definition
———————–|——————————————————
Audio Signal | The pattern of air pressure changes that produce sound.
Frequency | The number of cycles of a sound wave completed per second.
Amplitude | The height of a sound wave representing its loudness.
Fourier Transform | A mathematical tool to transform a signal from time domain to frequency domain.
Spectrogram | A visual representation of sound signals in 2-dimensional frequency-time domain.
Mel Scale | A non-linear mapping of frequencies used in audio signal processing.
Mel Frequency Cepstral Coefficients (MFCCs) | The most common feature representation technique for audio signal in speech recognition systems. It captures information about the human perception of sound.
