A JavaScript/TypeScript audio engine for the Web and Server capable of multitrack time stretching, pitch shifting, declarative effects, faster than realtime processing, and more!
Made possible by the guidance from @kirbysayshi in this comment in #10, along with this demo: WebAudioAPI
Note on Architecture
I aimed to keep the example as small/contained as possible, but felt that putting the analyser up in App.tsx was necessary since that's where new SmartPlayers are made. However, I could contain the new SmartPlayer to just the WaveVisualizer.tsx instead, and ignore the one that is passed in.
I could have based this component on the Code Editor instead, but went with JSON editor to avoid the risk of someone forgetting to click Eval.
Unrelated Question
Is there a fast way to go from "song term" search to "spotify preview URL"? I swapped out Roxanne during testing using the web api to find some alternative tracks, but was wondering if there was an existing GUI I could use.
Summary
This adds a basic example for using the WebAudio
AnalyserNodeAPI along with Canvas to visualize real-time audio playback frequency.Made possible by the guidance from @kirbysayshi in this comment in #10, along with this demo: WebAudioAPI
