Close AudioContext when recording visualization stops - #49
Merged
Merged
Conversation
Each recording created a new AudioContext for the waveform AnalyserNode but never closed it. Browsers limit the number of concurrent AudioContexts, so after ~40 record/stop cycles new contexts fail to start: getByteFrequencyData() returns silence (the waveform stops appearing) and audio decode/playback breaks until the page is refreshed. Close the AudioContext in the draw loop once the stream is no longer active, mirroring the cleanup already done in the download handler. Bug: b/538354264
