Preprocessing. The task of the program can be simplified and the analysis/synthesis results improved if the sound input is appropriately manipulated before running the program. Most important is to equalize the input signal. This controls what it means to find spectral peaks in order of decreasing magnitude. Equalization can be accomplished in many ways and here we …

STFT and melspectrogram are most popular method of representing input data in audio classification. ( It is generally believed that melspectograms are a better choice with smaller dataset.) However, when the authors performed varieties of experiences with these two preprocessing methods, they found that it wasn’t the case for them.

https://arxiv.org/abs/1709.01922
In this paper, we empirically investigate the effect of audio preprocessing on music tagging with deep neural networks. We perform comprehensive experiments involving audio preprocessing using different time-frequency representations, logarithmic magnitude compression, frequency weighting, and scaling. We show that many commonly used input …

Audio Processing. Steven W. Smith, in Digital Signal Processing: A Practical Guide for Engineers and Scientists, 2003. Audio processing covers many diverse fields, all involved in presenting sound to human listeners. Three areas are prominent: (1) high fidelity music reproduction, such as in audio compact discs, (2) voice telecommunications, another name for telephone networks, …

There are countless ways to perform audio processing. The usual flow for running experiments with Artificial Neural Networks in TensorFlow with audio inputs is to first preprocess the audio, then feed it to the Neural Net. What happens though when one wants to perform audio processing somewhere in the middle of the computation graph?

sine_wave = [np.sin (2 * np.pi * frequency * x/sampling_rate) for x in range (num_samples)] Copy. It says generate x in the range of 0 to num_samples, and for each of that x value, generate a value that is the sine of that. You can think of this value as the y axis values. All these values are then put in a list.
