24 alternatives to Real-time bandpass filter bank audio spectogram
Real-time bandpass filter bank audio spectrogram is an audio visualization tool that displays frequency content of sound in real time. It uses bandpass filters to analyze audio across different frequency ranges and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Real-time bandpass filter bank audio spectogram launched in 2020; newer entries below may have overtaken it.

This has been a pet project of mine for the past ~5 months. It consists of six visualizations: - Spectrogram: Implements the reassignment method for sharper time and frequency resolution. - Spectrum analyzer: A-weighted, frequency guidelines, loudest frequency tooltip. - Waveform: Colored based on frequency, loudness, or static - Oscilloscope: Tracks pitch and autocorrelates against a reference signal, provides stability. Also includes a regular zero-crossing trigger. - Stereometer & Phase meter: Linear and exponential scaling modes, adjustable windows. Multi-band correlation meter. -…

Last April I shared about my Resonate project here (https://news.ycombinator.com/item?id=43694157) A lot has happened since: the work I presented in much more detail at last June's International Computer Music Conference (ICMC) got best paper award. I also gave a talk at the Audio Developer Conference in Bristol last November, the video is on YouTube). This year's work, which I recently presented at this year's ICMC, starts with known techniques from the phase vocoder literature to build self-tuning filter banks that extract very efficiently the frequency components that are…

Hi HN, I’ve been working on a browser-based tool for exploring and debugging Web Audio API graphs. Web Audio Studio lets you write real Web Audio API code, run it, and see the runtime graph it produces as an interactive visual representation. Instead of mentally tracking connect() calls, you can inspect the actual structure of the graph, follow signal flow, and tweak parameters while the audio is playing. It includes built-in visualizations for common node types — waveforms, filter responses, analyser time and frequency views, compressor transfer curves, waveshaper distortion, spatial…

If you already know what bytebeat is, you don't need an explanation. If not, check my project :) Here is how it looks: SELECT mono(output( arraySum(x -> 1 / 6 * running_envelope(30 * (1 + x / 6), time, 0.05 * x, 0.005, lfo(0, 0.25, sine_wave, time / 8), 0.1) * sine_wave(time * 80 * exp2(x / 3)), range(12)))) FROM table; To check how it sounds, find the examples in the repository https://github.com/ClickHouse/NoiSQL

I’m happy to announce the first release of Roc Toolkit, version 0.1.0! Roc provides a C API for real-time audio transport. The user just writes a stream to the one end and reads it from another end. Roc, in turn, performs encoding and decoding, and, more importantly, deals with the problems re
