This study converts piano recordings to mel spectrogram and classifies them by SOTA pre-trained neural network backbones in CV. Comparative experiments show that SqueezeNet achieves a best classification accuracy of 92.37%.|该项目将钢琴录音转为为mel频谱图,使用微调后的前沿计算机视觉领域预训练深度学习骨干网络对其进行分类,对比实验可知SqueezeNet作为最优网络正确率可达92.37%
