Audio Analyzers

Inspect any video file in your browser: codec, resolution, real bitrate, HDR, color, audio tracks and platform-readiness checks. Free.

Inspect audio files for true quality — detect upsampled or re-encoded tracks by analyzing the spectrum.

Upload a recording and get its chords with fingering diagrams, key and tempo. Capo, transpose, slow-down and loop for practice.

Upload a song to detect BPM, musical key, and Camelot notation. Includes tap-tempo for manual detection.

Upload an audio file to identify its genre, mood, dominant instruments, BPM and musical key.

View, edit or strip ID3 tags, cover art and comments via WebAssembly

Analyze audio for signs of editing, splicing, or AI generation.

Find splices, cuts and edits in audio recordings using six forensic detectors with millisecond precision.

Embed an invisible watermark in your audio to prove ownership.

Slow any sound down to 500x without changing pitch and inspect it under a live spectrogram with note and frequency readout.

Transcribe any audio recording into notes, MIDI, and sheet music using AI.

Scan any score photo or PDF and hear the notes back.

Convert Guitar Pro (GP3-GP8, GPX) and MusicXML tabs to MIDI in your browser. Pick tracks, preview, and download.

Upload a track and get the list of instruments plus a map of where each one enters.

Compare two audio files side-by-side with objective metrics — LUFS, spectrum, dynamic range, ABX blind test, sample-level diff.

Compare your mix to a reference track: LUFS, spectrum, dynamics, stereo and precise recommendations.

Hearing which frequency is the problem is a skill built by repetition. Everything you need for that is here.

Reads a MusicXML or MIDI score and shows what the orchestra cannot play: notes out of range, no room to breathe, impossible harp chords.
