Three Wishes

If a jinni (or genie) grants you three wishes, what would you wish? I might guess something such as generic infinite riches, maybe even world peace. You know, sudden, instant gratification. That gibbon, please. Make it ride a scooter with jet. Or perhaps exploiting the technicality (loophole). Say, for instance, please grant me another x wishes , or better, another battalion of you , "you" being the jinni. How am I supposed to clone myself? — said the jinni. Unless the jinni stated the terms and conditions, we can surely find a cheeky way to get to the backdoor. And as for me, I might ignore the jinni politely. Such as, I thank thee for the generous offer, kind sir. Might I offer thee for a sugared roundel, nigh consumed, its orb defiled? Perhaps not, perhaps I'd say, Why? ⬆️ Indeed, just one word. You see, it will instantly break the spell. Because the bugger needs to explain the bugger in question. Since the bugger has a talkative nature, the ...

JavaScript: Browser-based Audio Analysis Using AnalyserNode

Greetings. 🎩 I will demonstrate the implementation of AnalyserNode to reveal (compute) the peaks and such from an audio source. This will only output the numbers rather than an elaborate animation. In this, we can choose whether to use a sample audio (hosted on a cloud storage) or a local audio file. Highlights of the flow: // 1. Create audio element audioElement = document.createElement("audio") // Make sure we convert the source to a proper Blob first, // not URL/path string like https://www.host... or local E:\path\to\file\... // Details in the code below the demonstration. audioElement.src = [Blob] // Then append the audio element to DOM // *** // 2. Setup AnalyserNode (use global variables to keep these) // Create audio context audioContext = new AudioContext() // Define the default FFT size fftDefault = 2048 // Create analyser analyser = new AnalyserNode( audioContext, { fftSize: fftDefault } ) // Create source node from the "audioElement" ab...
