Analyzing songs online

When built with ffmpeg or libav, aubio can read most existing audio and video formats, including compressed and remote video streams. This feature lets you analyze directly audio streams from the web.

A powerful tool to do this is youtube-dl, a python program which downloads video and audio streams to your hard-drive. youtube-dl works not only from youtube, but also from a large number of sites.

Here is a quick tutorial to use aubio along with youtube-dl.

0.4.4 released

A new version of aubio, 0.4.4, is available.

This version features a new log module that allows redirecting errors, warnings, and other messages coming from libaubio. As usual, these messages are printed to stderr or stdout by default.

Another new feature is the --minioi feature added to aubioonset, which lets you adjust the minimum Inter-Onset Interval (IOI) separating two consecutive events. This makes it easier to reduce the number of doubled detections.

New demos have been added to the python/demos folder, including one using the pyaudio module to read samples from the microphone in real time.

0.4.4 also comes with a bunch of fixes, including typos in the documentation, build system improvements, optimisations, and platform compatibility.

Sonic Runway takes aubio to the Playa

We just learned that aubio was at Burning Man this year, thanks to the amazing work of Rob Jensen and his friends on the Sonic Runway installation.

Burning Man is an annual gathering that takes place in the middle of a vast desert in Nevada. For its 30th edition, about 70,000 people attended the festival this year.

The idea behind Sonic Runway is to visualise the speed of sound by building a 300 meter (1000 feet) long corridor, materialized by 32 gates of colored lights.

Each of the gates would illuminate at the exact moment the sound, emitted from one end of the runway, reaches them.

The light patterns were created on the fly, using aubio to analyze the sound in real time and have the LED lights flash in sync with the music.

To cover the significant cost of hardware, the whole installation was funded by dozens of backers in a successful crowd-funding campaign.
