The mel spectrogram is a time-frequency representation of an audio signal that compresses high-frequency components and focuses more on low-frequency components . Analyzing sequential data or time series is a very relevant and explored task in Deep Learning. In this paper, we detail an approach to use convolutional filters to push past the inherent tradeoff of temporal and frequency resolution that exists for spectral representations. As future work, CNN architectures with custom 2D filters should, implementing a simple CNN with one-dimensional convolutional first la, constitute a robust architecture to achieve the goals of estimating correctness of bow-strok, executions. This is a closed-set speaker identification: the audio of the speaker under test is compared against all the available speaker models (a finite set) and the closest match is returned. To generate the feature extraction and network code, you use MATLAB Coder, MATLAB Support Package for Raspberry Pi Hardware, and the ARM® Compute Library. In order to process this information, deep learning models with convolution layers can be used to obtain feature maps. The proposed ensemble of deep MIL networks achieved a 0.98 AUC and 0.92 F1 score performance on the test set, using only a log mel-scaled spectrogram as data representation. Linear Prediction Coefficients estimation from mel-spectrogram implemented in Python based on Levinson-Durbin algorithm. Furthermore, we postulate that only when attention is directed toward a particular feature (e.g., pitch or location) do all other temporally coherent features of that source (e.g., timbre and location) become bound together as a stream that is segregated from the incoherent features of other sources. In particular, the example uses a Bidirectional Long Short-Term Memory (BiLSTM) network and mel frequency cepstral coefficients (MFCC).
