An audio waveform is a graphical representation of a sound signal. The horizontal axis represents time, and the vertical axis represents amplitude (volume). The peaks and valleys show the changing loudness of the audio.
This tool uses the Web Audio API to decode audio files and extract waveform data. All processing happens locally in your browser — files never leave your device.
All audio formats supported by your browser, including MP3, WAV, OGG, M4A (AAC), and FLAC. MP3 or WAV is recommended for best compatibility.
