CLUSTER AUDIO-DESKTOP-FILES · 9 ENTRIES · EARLIEST ENTRY 2013-02-24

Audio spectrogram analysis tools

This cluster consists of desktop and web tools for visualizing audio through spectrograms and analyzing frequency content, waveforms, and mastering metrics. The dated history is too thin to read a shape from — only three dated entries exist before the index start, predating coverage or with undated members. Traction is nominal: audio-equalizer, task195-echotrack, and MasVisGtk lead the activity signal, each with 0 stars.

ENTRY TIMELINE

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 9 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

  1. 01BLACKSITE2★24 days—hobbyDesktop workstation that replays recorded signal data, detects spectral peaks, and tracks frequency patterns appearing, changing, and reappearing over time.
  2. 02SDS-Sound1★11 dayslivehobbyDesktop sample browser that searches, previews, and downloads audio samples from Freesound for music producers, with a Japanese-language interface.
  3. 03simpleaudiospectral0★24 dayslivehobbyWeb application that analyzes audio files to detect lossy transcoding, upsampling, and other quality issues in claimed lossless tracks.
  4. 04audio-equalizer0★1 mo—hand-codedhobbyWindows audio utility that shapes the system sound response with a live spectrum analyzer and routes output to selected devices.
  5. 05MasVisGtk0★3 moliveopen sourceDesktop tool that analyzes audio files for mastering defects, plotting waveforms, frequency spectra, dynamic range, loudness, and peak versus RMS levels.
  6. 06Spek0★3 yrabandonedlivehand-codedopen sourceDesktop utility that renders spectrograms of audio files so users can visually inspect frequency content and audio quality.
  7. 07SpectralOli0★unknownliveBrowser-based audio tool for spectral livecoding with multi-loop support and spectrogram visualization.
  8. 08Spectrogram0★unknownliveWeb app that displays voice spectrograms to help visualize and analyze audio input.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
