The Metronome Method

From the previous method, Peak Definition, I continued to see what I could do better. It seems that everything was more connected than what I thought in some areas of the AUM DAW (digital audio workstation)  and other areas that was not. Sometimes technical literature does not always cover every aspect and functionality of a tool or equipment. Developers do not always have enough experience in every area they need to have experience in to create a well rounded technical explanation of a programs functionality that the average reader can comprehend. This means that the user or technician has to figure out the rest. That’s where I, Jamin Chavez, come in.

In trying to figure out a faster way to reduce or disintegrate excess BEM I needed a hybrid way to mix waveforms to increase efficiency and effectiveness. AUM Audio Mixer has two functionalities. One function is where the user can connect the channel to the MIDI control and the audio going through the channel can be controlled by the MIDI. Using “The Oscillator” only drives the rest of the functional plugins, and built-in plugins, to include the “Noise Gate”. To do this just go to “MIDI Route” and make sure the routing table is clear. Running “The Oscillator” with the MIDI Route clear enables the method to run faster than the limit of 999 beats per minute and goes as fast as the frequencies set in “The Oscillator” app itself.

I decided to leave the MIDI Route table clear and turn on the Metronome by itself. This provides clock benchmarks while listening to the onboard noise generator from “The Oscillator”. I began remembering some of MY electronics training and experience and wondered if the audio engine would calculate a 555 timing sequence. I got the idea from the 555 integrated circuit. I then looked up what 5 was in binary and that is basically a 101. Translated to how an audio engine would interpret that would mean that a sine wave set to 19555.7 Hz would be switching off and on at exactly that, 19555.7. The .7 helps the audio engine calculate the waveform even more efficiently including the RMS (rate mean second) because there is a small gap or delay in between the RMS and the Peak of each positive and negative portion of the waveform. A 1 means ON and a 0 means OFF in binary. The audio engine catches the incoming waveforms of a sine and rampdown sawtooth wave even better especially with the multiple Peak EQ’s modulating both waveforms. I had to tweak the “Noise Gate” and do more experimenting to ensure the downward expansion gate stayed closed or at least ran efficient no matter what valent waveforms or noises were present. Below are the settings. If YOU need a pictoral example look at the previous blog post.
