Spectrogram Python Packages

nnaudio

Audio processing by using pytorch 1D convolution network

colorsynth

A Python library for creating false-color images from Numpy arrays of spectral intensity

sonopy

A simple audio feature extraction library

shaderflow

🔥 Modular shader engine designed for simplicity and speed

audioflux

A library for audio and music analysis, feature extraction.

kapre

kapre: Keras Audio Preprocessors

sonore

Signals and stimuli for auditory research, built for Jupyter: generators, filterbanks, invertible spectrograms, binaural cues, spatialization, reverb and sound textures.

spectral-forensics

Spectral inspection toolkit: reassigned spectrograms beyond the uncertainty limit, lossy-transcode forensics, and invertible frequency-domain editing.

convolinear

Fluent signal processing for Python, one line at a time.

resonators

Rust implementation of the Resonate algorithm for low-latency spectral analysis, with Python and WebAssembly bindings

spectral-connectivity

Frequency domain estimation and functional and directed connectivity analysis tools for electrophysiological data

mel-cepstral-distance

A Python library for computing the Mel-Cepstral Distance (Mel-Cepstral Distortion, MCD) between two inputs. This implementation is based on the method proposed by Robert F. Kubichek in "Mel-Cepstral Distance Measure for Objective Speech Quality Assessment".

callistodownloader

A python package for downloading spectrograms sourced from the e-Callisto, which is an international network of solar radio spectrometers.

spwb

A DSP library and desktop application for measurement work: spectra, transfer functions, coherence, spectrograms and adaptive filtering

auvyon

AuVyon collects little helpers to handle media data.

signavis

Interactive waveform + spectrogram audio player for analysis, annotation, and embeddable previews (Web, Streamlit, Gradio)

tscv-vision

Computer-vision feature engineering for 1D time series. Convert sequences into images (e.g., Gramian Angular Fields, Recurrence Plots, Spectrogram-like maps) and extract robust visual features for downstream ML.

spectronote

🎧 Piano-perfect audio spectrogram

onc-hydrophone-data

Python tools for downloading Ocean Networks Canada hydrophone audio and spectral products, checking deployments, and generating custom edge-safe spectrograms.

spectoconvo

A python package to encode and decode messages in to audio spectograms

spectrographic

Turn an image into sound whose spectrogram looks like the image.

phase-spectrogram

Golang Mel Spectrogram and Spectrogram inversion

ppg-pre

ppg preprocessing (e.g., ppg> spectrogram, bandpass, moving average)

audio2spectrogram

This tool can be used to convert mp3 to processable wav files, generate chunks of wav's and generate spectrograms.
