Real-Time Pitch Estimation in Music Using Frequency Convolution Neural Network (FrCN) on Edge

Results show that frequency axis dilation is effective for low-parameter, noise-robust pitch estimation, and the proposed Frequency Convolution Network is also competitive with recent pitch estimation systems while using far fewer parameters.

Low-Rank Frequency Convolution and Noise-Range Augmentation for Real-Time Pitch Estimation on Edge Devices

The Frequency Convolution Network (FrCN) of earlier work is factored into a low-rank form, and the semi-orthogonal constraint used in TDNN-F is found to be redundant with the normalization inside the bottleneck, and accuracy is reduced when both are applied.
