Real-Time Pitch/F0 Detection Using Spectrogram Images and Convolutional Neural Networks (2504.06165v1)
Published 8 Apr 2025 in cs.SD, cs.AI, and eess.AS
Abstract: This paper presents a novel approach to detect F0 through Convolutional Neural Networks and image processing techniques to directly estimate pitch from spectrogram images. Our new approach demonstrates a very good detection accuracy; a total of 92% of predicted pitch contours have strong or moderate correlations to the true pitch contours. Furthermore, the experimental comparison between our new approach and other state-of-the-art CNN methods reveals that our approach can enhance the detection rate by approximately 5% across various Signal-to-Noise Ratio conditions.
