Waveform Viewer

About Waveform Viewer

This advanced audio waveform viewer lets you visualize and analyze audio files directly in your browser. Features include waveform visualization, spectrogram analysis, stereo channel split view, real-time peak meters, A-B loop for section repeat, markers, timeline ruler, and export to PNG/SVG. Perfect for audio analysis, music production, podcast editing, and sound design.

What audio formats are supported?

All common audio formats are supported including MP3, WAV, OGG, AAC, M4A, FLAC, OPUS, and more. The waveform is generated from the decoded audio data.

What is a waveform?

A waveform is a visual representation of an audio signal showing amplitude (volume) over time. The height represents loudness - taller peaks mean louder sounds, shorter sections mean quieter sounds. It helps you see the structure of your audio at a glance.

What is a spectrogram?

A spectrogram displays frequencies over time using colors. Brighter colors indicate louder frequencies. It's useful for identifying specific sounds, analyzing speech patterns, and detecting noise or artifacts in audio.

What are peak meters?

Peak meters show the real-time loudness level in decibels (dB). They help you monitor audio levels and identify clipping. The meters display left and right channels separately for stereo audio.

How do I use A-B loop?

Click the A-B button, then click on the waveform to set point A (start), then click again to set point B (end). The selected section will loop continuously. Click A-B again to cancel.

Can I export the waveform?

Yes! Click the export button to download the waveform as PNG or SVG format. This is useful for documentation, presentations, or sharing your audio analysis.

What is stereo split view?

Stereo split view shows left and right audio channels separately. This helps you analyze stereo imaging, identify channel imbalances, and see differences between channels.

Is my audio file safe?

Absolutely! All audio processing happens directly in your browser. Your audio file is never uploaded to any server. Everything stays private on your device.
