About us and what we do

ADIG was created with a vision of making new and inventive technologies for the music industry. Being musicians, we see solutions that does not yet exist.

The idea for developing the Human Synchronizer is to provide a real-time tempo control for the musician. Allowing him to manage the tempo of his gear from his playing, while he is playing. Gear such as delays, sequenzers, drum-machines, loopers, will aligne perfectly.

Furthermore, it is important for us to get rid of the click ticking in your ears while playing. We are therefore proud to introduce the Adig Human Synchronizer with its' superb tempo technology.

The ADIG tempo technology

ADIGs' cutting edge tempo technology is ideal for integration in sequenzers, drum machines, delays, loopers, digital pianos, in any DAWs, or simply as a stand alone tempo controller software.

Our tempo technology is made up of several sets of algorithms. From low level to high level these are:

- Onset detector,
- Tempo tracking,
- Beat detect.

The onset detector translates audio input into beat events. This translation is performed by our patent pending algorithm working both in time and frequency domain. We know of no technology that matches our algorithm, being perfect as the low level algorithm used in sequenzers for finding onset events from audio.

The tempo tracking system is our original algorithms, first shown at NAMM 2009. This makes it possible for the sequenzers to stay in synch with the player.

Our beat detect algorithm finds the tempo of an incoming audio or midi stream and syncs to this steam. The musician no longer requires to hear a click to perform.

All our algorithms work in real time. By being very efficient in nature, these algorithms can be used for having the musician control the machines live in performance as well as in studio situations.

Onset detector example

To show how our onset detector works, we have run it in 3 sound samples attached below, and illustrated to the right.

In the audio file, the original file is in the left channel, and the ADIG detected onsets are added to the right channel. The illustrations show the original sound on top and the result of the ADIG onset detector at the bottom. The files were imported into Ableton Live where we did a warping of the samples. Ableton Live sets tempo markers according to the beat detected, (shown as vertical, grey lines).

Having a look at the Red Hot Chilli Peppers sample, we see that Ableton does a good job at finding the tempo. The ADIG onset detector and the Ableton Live beats line up pretty neatly.

Looking at the more complex Susanne Vega sample, the correct tempo is found by having a look at the ADIG onset markers. The most common distance between the markers is usually used to determine the tempo. For the Vega sample, Ableton Live is not able to find the tempo.

Symphonic music is even more demanding for detecting tempos. The ADIG onset detector can even find onsets in music where the tempo information lies in pitch changes. The Ravel orchestral sample shows clearly a regular distance between onsets that can be used for tempo extraction.

For your convenience we have added a user interface window for adjusting spectrum sensitivity. Adjust sensitivity in the most relevant spectrum, where the most significant tempo information in that particular song, or the instrument you play, or the music genre, is at. In example, treble-range where beat is on high-hat, or in bass-range for kick-drum.
