Audio Waveform Visualizer
Station255's Waveform tool decodes any audio file in your browser (MP3, WAV, OGG, FLAC, AAC)
using the Web Audio API's decodeAudioData, samples the peak amplitude across a
configurable number of bars, and renders the result as a pixel-art PNG using a retro console
palette. No server, no upload — the audio stays in your browser.
Three waveform styles
Bars — classic waveform with individual bars growing upward from the baseline. Mirror — symmetric waveform centered on the midline, giving the classic music-player look. Filled — bars with a gradient overlay blending from the waveform color to the background.
Use cases
Music thumbnails for YouTube, SoundCloud, and Bandcamp. Podcast episode art. Twitch stream overlays. Beat-maker portfolio pieces. Discord server banners. Album artwork accents.
FAQ
What audio formats are supported?
Any format your browser's Web Audio API can decode — typically MP3, WAV, OGG Vorbis, FLAC, and AAC.
Does it use the left channel, right channel, or both?
Currently the tool analyzes channel 0 (left/mono). Stereo mixing is planned for a future update.
Can I use longer tracks?
Yes — the tool samples the entire file regardless of length. Very long files (>10 min) may take a few seconds to decode.
