Waveform Viewer

About Waveform Viewer

Why pay $30/month for Audacity Pro or Adobe Audition just to see a waveform? Podcasters spot dead-air gaps and umm/ahh clusters at a glance; musicians find the kick-drum hit to align a snare sample; voice actors check for breath pops and S-clicks; podcast editors verify levels stay above silence threshold and below clipping. This tool delivers studio-grade visualization free in your browser: zoomable waveform (100x), real-time spectrogram showing frequency content over time, stereo split view to debug L/R balance issues, peak meters with dB readouts, A-B loop for re-listening tricky sections, draggable markers for editing reference points, and PNG/SVG export for shipping waveform thumbnails to clients or social. Supports MP3, WAV, FLAC, OGG, AAC, M4A, OPUS up to 500MB. All processing browser-local — your unreleased tracks never touch a server.

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.
