Summary

Tune Transcriber is a free online tool designed to help musicians learn songs by ear. It allows users to slow down audio tracks without changing pitch, loop difficult sections, transpose the pitch, and use AI-assisted note and chord detection—all directly in the browser without requiring installation or account creation.

Features

• Slows down music to as low as 25% tempo while maintaining the original pitch.
• Loop any selected passage repeatedly for focused practice.
• Adjust playback delay to prepare before loops start (up to 5 seconds).
• Transpose pitch by octaves, semitones, or cents to match instruments or vocals.
• Provides AI-driven pitch detection showing polyphonic piano roll and chords.
• Displays single melody note detection and a spectrogram view for frequency analysis.
• Estimates tempo (BPM) and key automatically before playback.
• Supports loading audio files (MP3, WAV, M4A) or YouTube links directly in the browser without uploading data.
• Allows marking of sections and beats for easier navigation.
• Exports slowed down loops as MP3 files for offline practice.
• Autosaves workspaces to preserve progress.

Usage Scenario

The tool is ideal for musicians who learn songs by ear and want to isolate or slow down challenging parts to transcribe or practice effectively. Since it runs entirely browser-based, it is accessible without downloads or installs and keeps user data local.
