What’s new in Web Audio
Introduction It’s been a while since we said anything on Hacks about the Web Audio API. However, with Firefox 37/38 hitting our Developer Edition/Nightly browser channels, there are some interesting new features to talk about! This article presents you with some new Web Audio tricks to watch out for, such as the new StereoPannerNode, promise-based […]

People of HTML5 – Remy Sharp
HTML5 needs spokespeople to work. There are a lot of people out there who took on this role, and here at Mozilla we thought it is a good idea to introduce some of them to you with a series of interviews and short videos. The format is simple – we send the experts 10 questions […]

High Performance Web Audio with AudioWorklet in Firefox
Earlier this week, Audio Worklets landed in the release of Firefox 76. We’re ready to start bridging the gap between web audio and native. Developers can now leverage
AudioWorklet
to write arbitrary audio processing code. This exciting new functionality raises the bar for emerging web experiences like 3D games, VR, and music production. -
Writing Web Audio API code that works in every browser
You probably have already read the announcement on the Web Audio API coming to Firefox, and are totally excited and ready to make your until-now-WebKit-only sites work with Firefox, which uses the unprefixed version of the spec. Unfortunately, Chrome, Safari and Opera still use the webkitAudioContext prefixed name. Furthermore, as a result of the spec […]

audio data API – audio generation demo
At BarCamp Bankgkok 4, 16 year-old programmer, Thai Pangsakulyanont, did an awesome presentation (that I now know he hacked together in 2 hours before the presentation) on the Audio Data API in Firefox 4: audio generation demo. Simply, the demo uses the mouse button for a crash cymbal, mouse actions as an arpeggiator, and the […]

exploring music with the audio tag
Today’s demo comes to us from Samuel Goldszmidt. He’s a web developer specializing in audio applications at Institut de Recherche et Coordination Acoustique/Musique (IRCAM). IRCAM is a European institute covering science, sound and avant garde electro-acoustical art music. The demo uses XML to describe the various segments of a piece of music – Florence Baschet’s […]

A Real-Time Wideband Neural Vocoder at 1.6 kb/s Using LPCNet
This is an update on the LPCNet project, an efficient neural speech synthesizer from Mozilla’s Emerging Technologies group. LPCNet combines signal processing and deep learning to improve the efficiency of neural speech synthesis. Our recent work turns LPCNet into a very low-bitrate neural speech codec that’s actually usable on current hardware and even on phones.

LPCNet: DSP-Boosted Neural Speech Synthesis
LPCNet is a new project out of Mozilla’s Emerging Technologies group — an efficient neural speech synthesiser with reduced complexity over some of its predecessors. Neural speech synthesis models have already demonstrated impressive speech synthesis quality, but their computational complexity has made them hard to use in real-time, especially on phones. Our solution with LPCNet uses a combination of deep learning and digital signal processing (DSP) techniques.

What’s new in Web Audio?
The Web Audio API is still under development, which means there are new methods and properties being added, renamed, shuffled around or simply removed! In this article, we look at what’s happened since our last update in early 2015, both in the Web Audio specification and in Firefox’s implementation. The demos all work in Firefox […]
