We are often presented with a waveform or spectrogram for which it is helpful to suppress details in noise-dominated sections of time (in the waveform) or of time-frequency(“T-F”, in the spectrogram).
In keeping with the knowledge-based focus of SpeechMark, we are particularly interested in solutions based on broad principles rather than ones that must be determined in a subtle, complicated, or ad hoc fashion, whether by the user or by SpeechMark.
