Spectrogram low quality detect
WebA spectrogram is a visual representation of sound, displaying the amplitude of the frequency components of a signal over time. Unlike MFCCs and other transformations that represent lower level features of sound, spectrograms maintain a high level of detail (including the noise, which can present challenges to neural network learning). WebSep 3, 2024 · In this paper, we propose a deep-learning-based method to detect and cut out the interference in spectrograms. Then, we restore the spectrograms in the cut-out region. First, a fully convolutional neural network (FCN) is …

WebCracks are one of the most common factors that affect the quality of concrete surfaces, so it is necessary to detect concrete surface cracks. However, the current method of manual crack detection is labor-intensive and time-consuming. This study implements a novel lightweight neural network based on the YOLOv4 algorithm to detect cracks on a concrete … WebThe other side of the source-filter coin is that you can vary the pitch (source) while keeping the the same filter. Figure 2 shows wide and narrow band spectrograms of me going [aː], but wildly moving my voice up and down. The formants stay steady in the wide band spectrogram, but the spacing between the harmonics changes as the pitch does.
