Two Service Worker & Push Notification GOTCHAs

I have spent my day diving into Service Workers and Push Notifications since I wanted my webapp STQ (a German Star Trek trivia quiz app) to send out push messages to users. This has probably been the most wanted feature ever since. Addy Osmani’s guide on PWAs and this codelab by Sam Dutton on implementing push notifications are… Continue reading Two Service Worker & Push Notification GOTCHAs

Should your web audio app have a limiter?

Did you come across digital clipping in web audio apps? I certainly did several times (mostly in my own apps though). This undesired effect occurs when you play several sound sources at the same time, which results in a signal that is louder than the maximum of 0 dBFS.

WAV Builder

I made another little tool after CAAT, the WAV Builder. This time it’s not about testing filter algorithms, but synthesizing waveforms which are then rendered and saved as a WAV file.
