About Spectrograms
Wideband Spectrogram (5ms window): Shows formant structure clearly with good time resolution. Ideal for analyzing articulation, vowel quality, and temporal patterns. Formants appear as dark horizontal bands.
Narrowband Spectrogram (30ms window): Shows harmonic structure with good frequency resolution. Ideal for analyzing pitch, voice quality, and harmonic-to-noise characteristics. Individual harmonics appear as distinct horizontal lines.
