In python audio processing, we can use this function to hide the beginning and the end of audio data in an audio file. For example, we often use python python_speech_features package to extract audio feature: mfcc or fbank. Here we can use numpy.hanning () to winfunc.

https://dsp.stackexchange.com/questions/13238/numpy-correlate-and-autocorrelation-audio-signal
I want to calculate delay between an input and an output audio signal of my audio processing system. The input and output signals are available as signed 16 bit integers. To try out, I tried the autocorrelation of the input signal with the following numpy commands:

https://dsp.stackexchange.com/questions/2610/scipy-audio-processing
$\begingroup$ Scipy and Numpy together provide excellent tools for both real-time and offline processing of data. In combination with Cython or Ctypes (I tend to prefer the Cython approach), it's easy to operate on numpy arrays with low level fast operations written in C, if other libraries can't be persuaded to fit. $\endgroup$

The FFT is such a powerful tool because it allows the user to take an unknown signal a domain and analyze it in the frequency domain to gain information about the system. In the next entry of the Audio Processing in Python series, I will discuss analysis of audio data using the Python FFT function.

Audio Handling Basics: Process Audio Files In Command-Line or Python. This article shows the basics of handling audio data using command-line tools. It also provides a not-so-deep dive into handling sounds in Python. The two basic attributes of sound are amplitude (what we also call loudness) and frequency (a measure of the wave’s vibrations ...

ing audio signal processing applications. Overviews of Python language, NumPy, SciPy and Matplotlib are given, which together form a powerful platform for scienti c computing. We then show how SciPy was used to create two audio programming libraries, and describe ways that Python can be integrated with the SndObj library and Pure Data, two exist-
