Spectrogram vs mel spectrogram

WebSep 19, 2024 · Mel scale is the scale of pitches that can be felt by the listener to be equal in distance from one another. For example, a listener can identify the difference between the audio of 10000 Hz and 15000 Hz if the audio sources are in the same distance and atmosphere.

WebSpeech and music are human universals, and they have been the theme of numerous research topics in the social and natural sciences. From an engineering perspective, both speech and music information processing deal with symbolic and acoustic data, i.e., symbolic music notes or text, and acoustic music or speech audio signals. WebApr 12, 2024 · So I'm trying to replicate the process of obtaining MFCC from an audio file. So far I have obtained the Mel Spectrogram, and the last step is to perform Discrete Cosine Transform to the Mel Spectrogram. I've tried using scipy's dct() function to the spectrogram but it's still not quite what I'm looking for.

WebFeb 24, 2024 · Mel Spectrograms work well for most audio deep learning applications. However, for problems dealing with human speech, like Automatic Speech Recognition, you might find that MFCC (Mel Frequency Cepstral Coefficients) sometimes work better.
