Getting Started with Web Audio API

Getting Started with Web Audio API
Before the HTML5 <audio> element, Flash or another plugin was required to break the silence of the web. While audio on the web no longer requires a plugin, the audio tag brings significant limitations for implementing sophisticated games and interactive applications. The Web Audio API is a high-level JavaScript API for processing and synthesizing audio in web applications. The goal of this API is to include capabilities found in modern game audio engines and some of the mixing, processing, and filtering tasks that are found in modern desktop audio production applications. Getting started with the AudioContext An AudioContext is for managing and playing all sounds. A single instance of AudioContext can support multiple sound inputs and complex audio graphs, so we will only need one of these for each audio application we create. The following snippet creates an AudioContext: For WebKit- and Blink-based browsers, you currently need to use the webkit prefix, i.e. webkitAudioContext. Volume:

Home | Ubuntu Studio Create a stylish HTML5 template from scratch HTML5 is certainly one of the latest buzzwords in the web community. It isn't something new anymore and we've already seen how cool it is. Features like simplified doctype, more semantic markup, input types and placeholders are just some of the reasons you'd like to use a HTML5 template. So, today we're going to build a HTML5 template using the full power of CSS3. View demo The HTML5 template design Here's a screenshot with the HTML5 template layout we're going to code: As you may notice, the above HTML5 template is simple, minimal and stylish - thanks to the CSS3 awesome features. The not-so-secret ingredients: Simple logo using Google Font APINice drop shadow effects.Pattern background using data URI scheme.Vertical drop down menu animated with jQuery.Arrow shapes made with pseudo-elements.CSS3 gradients. A word on data URIs I wanted to create this HTML5 template demo without using any images and I made it. So the result is something like that: The encoded image is basically a pattern. The CSS

bfirsh/dynamicaudio.js - GitHub Web Audio Examples Web Audio Examples The Web Audio API introduces a variety of new audio features to the web platform. It can be used with the canvas 2D and WebGL 3D graphics APIs for creating a new generation of games and interactive applications. The API is capable of dynamically positioning/spatializing and mixing multiple sound sources in three-dimensional space. It has a powerful modular routing system, supporting effects, a convolution engine for room simulation, multiple sends, submixes, etc. These APIs are currently under development and are described in this specification document. Please direct any feedback to the W3C audio mailing list - public-audio@w3.org. Getting Started *** These samples require a browser which supports the Web Audio API Mac OS X, Windows, and Linux Builds are available in stable releases of Chrome. More cutting-edge builds are available in the Canary builds. Mac OS X Web Audio is available in Apple Safari 6 in Mountain Lion, and in iOS 6. Firefox Samples More Demos Getting Started

Dive Into HTML5 facebook/facebook-php-sdk - GitHub wami-recorder - A JavaScript / Flash solution to recording audio from a browser. As of this writing, most browsers still do not support WebRTC's getUserMedia(), which promises to give web developers microphone access via Javascript. This project achieves the next best thing for browsers that support Flash. Using the WAMI recorder, you can collect audio on your server without installing any proprietary media server software. The WAMI recorder uses a light-weight Flash app to ship audio from client to server via a standard HTTP POST. Apart from the security settings to allow microphone access, the entire interface can be constructed in HTML and Javascript. Try it out below: This project contains both client and server-side code. hg clone The Client The Flash app exposes most of its important parameters and functionality to the Javascript. Wami.startRecording(myRecordURL);Wami.stopRecording(); Wami.startPlaying(anyWavURL);Wami.stopPlaying(); The Server Wami.startRecording(' Ok, there is really no catch.

How to Create an Audio Player in jQuery, HTML5 & CSS3 [Tutorial] Topic: jQuery / CSS3Difficulty: Intermediate / AdvancedEstimated Completion Time: 30 mins Today’s tutorial we will code an Audio Player from Impressionist UI by Vladimir Kudinov. We will code it with CSS3 for the styling and the “MediaElement.js” for the functionality. MediaElement.js is a HTML5 audio and video player that also works for older browsers using Flash and Silverlight to mimic the HTML5 MediaElement API. Step 1 – Downloading MediaElement.js First we need to download the “MediaElement.js” script and extract it. flashmediaelement.swfmediaelement-and-player.min.jssilverlightmediaelement.xap Then copy all these three files to the same directory, I will copy for my “js” folder. Step 2 – HTML Markup Now, we need to link to the jQuery Library, we can host it locally or use the one hosted by Google. To create the player we will add a <div> width the class “audio-player”. To finish we need to add this code before the ending of the </body> tag. Step 3 – Container Styles Conclusion

Websockets Server - Cookbook As explained in this webpage, the Websocket protocol allows full-duplex, bi-directional communications between a server and clients. For this WebSocket tutorial, we will need to implement a server. We chose the Tornado Websocket server for our Internet of Things project. In this tutorial, we will present an example of how to get the Tornado Server running using websockets. This tutorial is divided into two parts: A Hello World which uses Tornado A websocket streaming example which uses Websocket4j. 1 - Hello World! 1.1 - Server side: Tornado¶ Warning Tornado only runs on Unix-like platforms. Installation¶ First, download the sources, unpack and follow the readme. For more information concerning the installation, you can go here Code¶ You can find all the documentation you need here, but I will explain the main parts of the following basic Tornado Websocket server program. The main idea is to define a class inherited from the WebSocketHandler class. open on_message on_close In our case: Code¶
