I solved an annoying issue by building my own real-time audio Chrome extension

Short summary

A developer shares lessons from building FreqWave EQ, a Chrome extension providing an 8-band equalizer and voice-enhancement modes for browser audio using React, TypeScript, and the Web Audio API. Key learnings include debugging subtle audio attenuation, working around chrome.tabCapture's fullscreen limitation, and properly implementing a DynamicsCompressorNode for the Leveler mode. The extension uses a Manifest V3 architecture with an offscreen document hosting the audio graph.

  • •FreqWave EQ is a Chrome extension for browser audio enhancement using Web Audio API
  • •Key bugs solved: audio attenuation, tabCapture fullscreen conflict, and DSP preset implementation
  • •Architecture uses MV3 offscreen document for audio processing since service workers can't access Web Audio API
