WebJan 19, 2024 · A spectrogram can be defined as the visual representation of frequencies against time which shows the signal strength at a particular time. In simple words, a spectrogram is nothing but a picture of sound. It is also called voiceprint or voice grams. A spectrogram is shown using many colors which indicates the signal strengths. WebThis codebase provides PyTorch implementation of some librosa functions. If users previously used for training cpu-extracted features from librosa, but want to add GPU acceleration during training and evaluation, TorchLibrosa will provide almost identical features to standard torchlibrosa functions (numerical difference less than 1e-5).
