Myten om grupparbetets förtjänster följer oss inte bara under studietiden, från lågstadiet till högskolan, utan återfinns även inom arbetslivet. Till exempel påstås öppna kontorslandskap ofta göra arbetsplatsen mer social och hävdas förenkla utbytet av idéer mellan medarbetare. Men i själva verket innebär de mer stress, psykisk ohälsa och koncentrationssvårigheter.

The sketch is an audio visual experiment that uses Web Audio API for sound sythesis/processing and THREE.JS for WebGL 3D rendering. The background music is being generated in real-time using Web Audio API while each face of the floating octahedron has a certain sustaining note which allows you to create evolving arpeggios and textures by clicking different faces. Clicking anywhere else will change the color of the background objects which combined with mouse movment results in interesting textures in the background as well as subtle stereo panning on the background sounds. Runs best on Google Chrome.

Granular synthesis is a method of sound synthesis based on splitting the audio into small pieces and playing them with short intervals. After loading a sample, you can start creating grains by clicking and holding your mouse on the waveform. The X axis will determine the position and Y axis will change the amplitude of each grain. This app also has multi-touch support for up to three voices and real-time manipulation of settings. Tested on: Google Chrome,Firefox, Safari, Chrome iOS (iPad), Safari iOS (iPad) Libraries used: Web Audio AP, Processing.js, Bootstrap 3,jQuery Knob. Performance Tip: Try using a quick attack and release as well as low density when using multi-touch for better performance.

Web Audio API Oscillators is a tutorial that will give you a deeper understanding of how to generate sounds with the Web Audio API in your browser.

Learn how to use the Web Audio API by creating a browser-based audio synthesizer.

Modern web browsers provide a rich set of APIs; some of which have been around for a long time, and have since been used to build powerful web applications. Web Audio API has been popular among HTML5 game developers, however, the Web MIDI API and its capabilities have yet to be utilized. In this tutorial, Toptal ...

I'm trying to learn how to use the web audio api properly and I'm running into a bit of confusion. In my project, I'm trying to replicate the functionality of an old 1982 Harman/Kardon receiver. (...

03-07-2015 Update: Updated the example, it now works with the latest versions of Chrome and Firefox With the Web Audio API you can have advanced audio processing directly inside your browser. This API specifies a whole bunch of nodes you can use to create your audio processing pipeline. In a previous article I showed a number of these components, and how they can be used together to play back sound and visualize the results. In this second article in the series on the Web Audio API we’re going to look a bit closer at the following subjects: Filter node: How do you use the various filter nodes that are available. Oscillator node: Use a tone generator as audio input. Microphone input: Record and visualize the input from the microphone.For those who want to directly dive into the filters, I’ve created a web application that allows you to experiment with Web Audio filters (click the image):.The controls of this application shouldn’t be too hard. At the top you’ve got three settings: Select the inputs that should play: Music will loop a 30 second piece of classical music, Microphone will use the microphone as input and Triangle creates a "triangle"wave (very noisy). More than one can be selected, they will be automatically mixed. Configure the filter to use: By changing the dropdown and using the sliders you can configure the filters. When you hover over "info" you're shown information on what slider does what. Select what output to use: You can enable each of the outputs separately. The visual ones are shown at the bottom. When enabling "speaker" watch out when using "Triangle" input.Whenever you change something, this change is immediately reflected in the audio configuration. So by sliding the controls of the filter you can immediately see (and hear) what happens.Using filter nodesWe won’t dive too deep into the various nodes in this article. If you want to know the details of the “Web Audio API” look at the previous article I wrote on this subject. With a filter node you can, as the name implies, filter certain parts of your audio stream. You can for instance filter out all the lower frequencies, or make the bass more pronounced. This API offers the following set of filters: LOWPASS: A lowpass filter allows frequencies below the cutoff frequency to pass through and attenuates frequencies above the cutoff. LOWPASS implements a standard second-order resonant lowpass filter with 12dB/octave rolloff. HIGHPASS: A highpass filter is the opposite of a lowpass filter. Frequencies above the cutoff frequency are passed through, but frequencies below the cutoff are attenuated. HIGHPASS implements a standard second-order resonant highpass filter with 12dB/octave rolloff. BANDPASS: A bandpass filter allows a range of frequencies to pass through and attenuates the frequencies below and above this frequency range. BANDPASS implements a second-order bandpass filter. LOWSHELF: The lowshelf filter allows all frequencies through, but adds a boost (or attenuation) to the lower frequencies. LOWSHELF implements a second-order lowshelf filter. HIGHSHELF: The highshelf filter is the opposite of the lowshelf filter and allows all frequencies through, but adds a boost to the higher frequencies. HIGHSHELF implements a second-order highshelf filter PEAKING: The peaking filter allows all frequencies through, but adds a boost (or attenuation) to a range of frequencies. NOTCH: The notch filter (also known as a band-stop or band-rejection filter) is the opposite of a bandpass filter. It allows all frequencies through, except for a set of frequencies. ALLPASS: An allpass filter allows all frequencies through, but changes the phase relationship between the various frequencies. ALLPASS implements a second-order allpass filterYou create a filter like this:var filter = context.createBiquadFilter();filter.type = 3; // In this case it's a lowshelf filterfilter.frequency.value = 440;filter.Q.value = 0;filter.gain.value = 0;And just like all the other nodes, you use “connect” to add this to the audio processing pipeline. And basically that’s all there is to using filters. The following screenshot show the output of the spectrometer when using a LOWPASS filter. In this example I’ve used a “Triangle” source. A Triangle is build up of a number of frequencies, so nicely allows us to see what happens when we start playing around with filters. To get this effect I’ve moved the frequency slider up and down, and as you can see, certain highter frequencies are blocked by the filter.If we look at the HIGHPASS filter we see exactly the opposite when sliding the frequency up and down.Interesting stuff, right! If you want to know more about the filters look at the BiquadFilterNode section in the W3 API, or experiment with the filter playground I created. Oscillator nodeIn the previous section we used a triangle as our waveform. We can create this waveform (and some others) directly from the Web Audio API.var osc = context.createOscillator();osc.frequency.value=600;osc.type=2;Here frequency is the frequency of the wave the oscillator should produce, and type defines the waveform.const unsigned short SINE = 0;const unsigned short SQUARE = 1;const unsigned short SAWTOOTH = 2;const unsigned short TRIANGLE = 3;const unsigned short CUSTOM = 4;This results in the following wave forms:Sine:Square:Sawtooth:Triangle:The final one, which I didn’t show, is the custom one. Here you can supply a Wavetable, which is a set of sine terms and cosine terms that together make up the waveform.So, enough for the oscillator node. Final item on the list is how to use your microphone as input.Microphone inputIn a previous article on capturing audio in the browser, I already showed you how you can access the microphone. To use it in the Web Audio API we only need to take a couple of steps more. Before we look at how to do this, first we have to make sure chrome can access your microphone. Go to “chrome://flags” and make sure the following is enabled:To use the microphone as input all we need to do now is the following:navigator.webkitGetUserMedia({audio:true},function(stream) { mediaStreamSource = context.createMediaStreamSource(stream); mediaStreamSource.connect(filter); });We use the getUserMedia call (prefixed for chrome) to ask access to the microphone. Once we get it, we connect this source, just like we would any other source.That’s it for this part on the Web Audio API. So start playing around with the filter playground and let me know if you’ve got any questions.
