About this multi-band audio graphic equalizer

Preview 5 or 10 equalizer bands live with pop, rock, vocal and bass presets, or render a separate WAV. Local audio must be smaller than 50 MB Processes streaming audio and video buffers directly in the browser using HTML5 Media and Web Audio APIs with zero server uploads.

Audio and video decoding pipeline

The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Choose a preview file, play it, then change 5 or 10 bands, individual gains or a preset while listening. Pause and seek retain the source position. Clear and leaving the page release playback. Preview runs at 48 kHz through serial peaking filters with Q=1. Gains move to their new values over 20 ms. Changing band count rebuilds the chain at the current position and resets to Flat; a brief interruption is possible. Boosts may clip. Preview and WAV export use separate files and settings; live changes are not recorded. The browser renders a serial chain of 5 or 10 peaking BiquadFilterNode filters with Q=1. Five bands use 60, 250, 1000, 4000 and 10000 Hz. Ten bands use 31.25, 62.5, 125, 250, 500, 1000, 2000, 4000, 8000 and 16000 Hz. Flat, pop, rock, vocal and bass presets set fixed gains. Switching band count resets to flat. Files stay on this device.

Worked media transformation example

Scenario: Multi-Band Audio Graphic Equalizer

Sample input:

/examples/audio-stereo.wav

Processing: In the WAV section, choose audio and settings, then render, preview and download the completed result.

Illustrative output:

Load /examples/audio-stereo.wav, choose 5 bands and Flat, and render. Expected: stereo 48 kHz PCM16 WAV with 72,000 frames and unchanged unity-gain samples within PCM16 rounding. Choose Bass to set gains [6, 3, 0, −1, −2] dB and render again.

Buffer duration & codec support limits

Operational constraints and validation boundaries: Both inputs must be nonempty and smaller than 50 MB (50,000,000 bytes). Gains range from −12 to +12 dB. WAV rendering remains 48 kHz PCM16; metadata is not retained. The WAV player needs a new render after settings change. Live controls affect only the separate preview. Boosts can clip; lower gains if needed.

Audio and video rendering in Multi-Band Audio Graphic Equalizer depends on browser hardware and supported media codecs. Verify playback compatibility on your target platforms.

In-memory audio-video processing boundary

File buffers and document assets in Multi-Band Audio Graphic Equalizer are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
