🎙️ Fast, installable, in-browser audio spectrum visualizer. Support for both realtime and audio files!

WavvieW: Analyzes the noise-wave-generator, synthesizer, audio files, input-mic_line-in with Oscilloscope and Spectrum FFT.

Kick drum keyfinder.

A basic sound visualizer in Python, to transform an audio file in a little movie!

autofft is a Matlab package which performs the time-frequency analysis without the need of Signal Processing Toolbox™. It mimics options of the Brüel & Kjaer FFT analysers and focuses on fast and accurate estimates of averaged autospectra (also called modified periodograms) and spectrograms.

Online web based mel-spectrum, power spectrum, FFT analyzer for speech and music processing

Chat using „enhanced“ end-to-end-enryption and modulation of audio signal in isolated device, ensuring privacy, anonymity and cybersecurity.

An audio visualizer written using soundcard, scipy and pyqtgraph. Supports internal and microphone audio. Live waveform, buffered, hanning, FFT (frequency domain) etc.

Решение задач по анализу временных рядов: детекция пиков QRS на сигналах ЭКГ с помощью ML, прогнозирование заболеваемости COVID с помощью LSTM и др.

AudioSpectraCLI is a command-line tool that provides real-time FFT visualization of audio spectra. It captures audio input from the microphone and displays the corresponding frequency spectrum directly in the terminal window, allowing users to monitor and analyze audio signals without the need for graphical interfaces.

Audio Quality Measurement Software

Discrete / Fast Fourier Transform and Inverse FFT with Excel VBA

This is a Python GUI Application Developed by Anshuman Biswal to Perform Fast Fourier Transform (FFT) on a given Signal Sequence, it is written in Python 3.8 and TKinter. Users can find DFT and IDFT of 4-Point,8-Point signal sequence in Frequency and Time Domain using Radix Algorithm, Also Linear Convolution and Circular Convolution using Radix.
