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

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

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

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.
