We’re working on several new features for the Tryphon stream platform.

We’ve deployed a new http frontend on For the moment, it supports .. stream redirection (to one of our available stream servers) and several playlist formats (like pls or m3u).

The next features are under development. One of them will use the fresh, an customized/centralized/simplified soundmanager2+360ui player.

Make noises

Several sounds are commonly used in audio and acoustic domains, like a 1000 Hz tune, a white noise, or a pink noise.

Simple tools like sox (“the Swiss Army knife of sound processing programs”) can generate them for you in a second :

$ sox -n -b 16 -r 44100 -c 2 sine.flac synth 10:00 sine 1000 fade q 10 10:00 10

$ sox -n -b 16 -r 44100 -c 2 whitenoise.flac synth 10:00 whitenoise fade q 10 10:00 10

$ sox -n -b 16 -r 44100 -c 2 pinknoise.flac synth 10:00 pinknoise fade q 10 10:00 10

The fade part is optional. The duration (10:00 here) can be customized according your need.

No more excuses to setup your audio chain correctly ;)
