Skeletune

Audio Analyzer

Drop a track and Skeletune reads its key, tempo, length, loudness and format at once, then hands the same decoded file to any tool without analysing it twice.

Both attempts count as one identification.

Identify a track

Identification sends a 12-second audio sample to the recognition service. Nothing else leaves your device.

Audio files stay on the machine in front of you: every tool decodes and analyses audio locally, because it all runs in your browser.

The specimen-plate layout keeps the tool first and the pitch second: load a track, read the result, then scroll only if you want background notes about the tool.

About this tool

This free online audio analyzer is the front door of SKELETUNE. Instead of choosing a tool first, you drop a file once and the plate fills in with everything measurable about it: musical key with its Camelot code, tempo in BPM, exact length, integrated loudness in LUFS and the technical format. Every number is computed by your own browser.

From there the same decoded file travels with you. Opening Pitch & Tempo from a tab reuses the audio that is already in memory, so nothing is decoded or analysed a second time and nothing is ever uploaded to a server.

SCAN can also name the track. Press “What’s playing?” and Skeletune listens through your microphone for a few seconds, or identifies the file you already loaded from a twelve-second excerpt. Only that short sample is sent to the recognition service — the rest of your audio stays on this machine.

How it works

  1. 01

    Drop the file

    Drag an MP3, WAV, M4A, FLAC or OGG anywhere onto the plate, or click it to browse. The file stays on your machine.

  2. 02

    Read the measurements

    The waveform draws from real data and the tabs unfold with key, BPM, length, loudness and format as the analysis lands.

  3. 03

    Continue in a tool

    Pick an action tab to open a tool with the file already loaded. Tools still in preparation are marked and never pretend to work.
