Mel spectrogram inversion with stable pitch
Web4 dec. 2024 · Key to improving the pitch stability is the choice of a shift-invariant target space that consists of the magnitude spectrum and the phase gradient. We discuss the … Webincreased by increasing the number of mel channels. Gener-ated spectrograms are converted back to time-domain sig-nals using classical spectrogram inversion algorithms. We experiment with both Griffin-Lim [18] and a gradient-based inversion algorithm [10], and ultimately use the latter as it generally produced audio with fewer artifacts. 3.

Estimate a STFT in normal frequency domain from mel frequency domain. It minimizes the euclidian norm between the input mel-spectrogram and the product between the estimated spectrogram and the filter banks using SGD. n_stft ( int) – Number of bins in STFT. See n_fft in Spectrogram.
