Sound for Javascripters
JavaScript の経験のレベルとしては、ある程度 ES2015+ のシンタックスに慣れていることを想定していますが、ES2015+ の実用的な書き方に慣れていない人にとっても有益な本であると思います。なぜなら async / await , array.from() , HOF = High Order Function といったモダンな書き方を積極的に取り入れているからです。
Audio worklet design pattern | Blog | Chrome for Developers
The previous article on Audio Worklet detailed the basic concepts and usage. Since its launch in Chrome 66 there have been many requests for more examples of how it can be used in actual applications. The Audio Worklet unlocks the full potential of WebAudio, but taking advantage of it can be challenging because it requires understanding concurrent programming wrapped with several JS APIs. Even for
Getting Started With The Web MIDI API — Smashing Magazine
Is it possible to use digital musical instruments as browser inputs? With the Web MIDI API, the answer is yes! The best part is, it’s fairly quick and easy to implement and even create a really fun project. In this article, Peter Anglea will cover the basics of MIDI and the Web MIDI API to see how simple it can be to create a web app that responds to musical input using JavaScript. As the web cont
Audio Worklet is now available by default | Blog | Chrome for Developers
Chrome 64 comes with a highly anticipated new feature in Web Audio API - AudioWorklet. Here you'll learn concepts and usage to create a custom audio processor with JavaScript code. Take a look at the live demos. The next article in series, Audio Worklet Design Pattern, might be an interesting read for building an advanced audio app. Background: ScriptProcessorNode Audio processing in Web Audio API
Exceeding the buffering quota | Blog | Chrome for Developers
Or other limited memory Chrome device. So what do I do? Since the amount of supported data varies so widely and you can't find the amount of data in a SourceBuffer, you must get it indirectly by handling the QuotaExceededError. Now let's look at a few ways to do that. There are several approaches to dealing with QuotaExceededError. In reality a combination of one or more approaches is best. Your a
Hello WebMIDI
Inspired by this talk by Jean-Philippe Côté I saw at Web Unleashed in Toronto last month, I thought I should dust off the old midi cable. MIDI? MIDI is a protocol that various music and lighting devices use to talk to each other. Believe it or not v1.0 of the spec from 1983 is still the one in use, remaining largely unchanged. In a world where we don't know if we're using JavaScript, ECMAScript7
JavaScriptでMIDIファイルを解析してみる 1 - Qiita
MIDIの構造について ここの解説をもとに解析してみます。 ちなみにMIDIファイルのことをSMF(Standard MIDI FILE)と呼びます。 なので以降SMFと呼びます。 使用する環境 Node.js SMFを16進数データとして読み込む 解析するために16進数並びのテキストデータとして読み込みます。 こんな感じです。 /** *midiファイルを読み込んで16進数テキストを返します。 *@param {string} filepath 読み込むMIDIファイルのパス *@callback コールバック *@return {string} 16進数テキスト **/ var fs=require("fs"); module.exports=function(filepath,callback){ fs.readFile(filepath,function(err,data){ if
