Spectrogram resolution

WebNov 8, 2024 · We compared model performance and training speed for different combinations of spectrogram creation parameters. We identify three main takeaways: First, mel scaling uniformly does better than frequency scaling. Second, high resolution spectrograms lead to longer training times, as well as lower model performance. WebApr 21, 2016 · I am trying to determine the amplitude envelope of specific frequencies over time, from a sample of an instrument (a trumpet). I use the spectrogram function to find the amplitude of each frequency bin over time. Knowing that a harmonic lies within a certain bin, I can plot that particular bin against time to produce the following figure:
