Oscilloscope Music Download BEST

So I recently got a tektronix 465 oscilloscope specifically for reading audio waveforms/voltage that comes out of my reciever. I saw somewhere that you need an isolated power supply when testing equipment. Which isn't that what I'm technically doing? But I also saw that you supposedly don't need one for something basic like audio waveforms. I've heard that your equipment can be ruined as well as a possibility of being shocked if a ground loop happens, which I guess an isolated power supply would prevent. I don't want to ruin anything, nor get shocked lol. So do I need one or not? I would appreciate quick responses because I'm eager to get this thing plugged in haha. Thank you.

Any help would be greatly appreciated! I plan on making oscilloscope music and art in the future, and ant to male sure my set up woks properly before I start putting content on the internet. Thank you for your time and effort!

my next idea was to record the sound separately with audio recorder and then maybe follow this in laserOs

" Click the star logo, and assign the mode/fx to a custom playlist. Set duration if going to setup a timeline. In music playlist (click music icon), select a song, click star, select custom playlist, and you sync play them. "

An oscilloscope is used to display and measure a voltage signal that is plotted against time. An oscilloscope in XY mode plots a signal against another signal sort of like a parametric equation. This project uses an oscilloscope in XY mode to display images produced by a sound file.

The original idea for the project was to convert an old Cathode Ray Tube (CRT) television set into an XY oscilloscope and use that to display the images. This can be done by disconnecting the deflection coils. When you disconnect the horizontal coils a vertical line appears, and when you disconnect the vertical coil, a horizontal line appears. All I had to do was connect the audio source to the deflection coils and I would have an XY oscilloscope. Unfortunately, I ran into several problems.

After all of these problems, I was able to find a pretty simple solution; an XY oscilloscope emulator program that took audio as an input. Once I found this program, I switched from focusing on creating an oscilloscope to creating a way to produce an audio file from an image to display on an oscilloscope.

Here is an example of the process with the instructables robot. First download an image of the instructables robot and save it as "image.png" into your MATLAB working folder (same place as "EdgeDetect.m"). Make sure the image doesn't have anything you want to be detected or it could add a bunch of unnecessary coordinates into your sound file. Run the EdgeDetect program and the image will be converted to gray-scale, and have it's edges detected and stored as a sound file named "vector.wav". Next open up the sound file in Audacity or another sound editing program. Open up your oscilloscope emulator program (link in previous step), set the sample rate to 192000 Hz, press start, click the microphone button, and select the line in option. In Audacity press "shift + spacebar" to play the sound file in a loop. The image should appear on the oscilloscope emulator.

I want to use your code for a project with live drawing to sound to oscilloscope but how do I execute the code? Just for one image, I put an image.png in the folder and start/save the code, do I need any specific program to run the code? Right now I'm using VSC.

Eric, do you mean that you use the signal generator?

I am not using any math expression with the signal generator. I directly link to XXY Oscilloscope microphone input from the music playing from Roon. This can be done using audio routing software. I am using Soundflower ( ) on Mac to wire the sound output to the input.

These are the settings i prefer (signal generator functions do not matter):

,0.8,0,0,0,0,0,2,0,sin(2PIat)cos(2PIbt),cos(2PIat)cos(2PIbt),0,1,0,1,239,-0.01,0,0

Oscilloscopes generally have an XY mode. Analog oscilloscopes show XY displays in real time where digital oscilloscopes have to acquire the signal and then display the data so generally are not as good. Our demonstration board draws the Wizard, Tek Bug, and Tennis in XY mode. Alan Wolke has a nice tutorial #288: Comparing XY Mode on Analog and Digital Oscilloscopes.

Oscilloscopes have been used to display stereo signals in XY mode for decades. During the 1970s and 1980s many famous stereo component manufacturers sold an oscilloscope as part of their component system. The oscilloscope would be used to display stereo, 4 channel, and FM multipath signals. Tektronix made a 760A stereo audio monitor which was used in broadcast facilities to monitor the quality of the audio signals.

Jerobeam Fenderson at oscilloscopemusic.com has developed some great music that displays fantastic images on an oscilloscope in XY mode. We have an oscilloscope music exhibit at the museum which plays a number of his compositions.

In a nutshell, you connect the left and right channel of your audio source to an oscilloscope while playing it through an amplifier. Set the oscilloscope to X/Y mode and the oscilloscope will draw a picture according to the instantaneous audio voltages. But the art is to create audio signals which draw a nice picture and create an equally pleasant sound.

The video shown above is an XY trace taken on an oscilloscope which is being fed a carefully crafted audio file. The oscilloscope is drawing a single bright point of light, with the left audio channel controlling the X axis position of that point and the right audio channel controlling the Y axis position. Varying the amplitude of those two channels together allows that point of light to be used as a pen, drawing shapes on the 2D screen. You can find a much more detailed explanation of what's going on here from Smarter Every Day.

As soon as I saw this, I immediately wanted to see if I could recreate the same kind of visualization from that same audio. I do have an oscilloscope, but it's all the way in the other room, so I decided to see if I could recreate the result in code.

My goal here is to take the audio track from a source like this video as input and recreate the video, showing the result you would see by playing that audio file into the X and Y channels of an oscilloscope.

To do this, I'm going to emulate the behavior of the oscilloscope trace. I'll start off with a black canvas. At each audio sample, I'll use the left and right channel amplitudes to pick an X and Y coordinate in that canvas, and I'll make that pixel white. This is basically what the oscilloscope does in XY mode: it is always drawing a bright dot, and the X and Y channels determine where that dot is.

You'll notice from all the oscilloscope music videos, however, that you can see more than just a single dot at a time. In fact, you can see smooth lines that don't seem to be made up of individual points. This happens because the oscilloscope display itself has some persistence. An electron beam is used to illuminate a single point on the screen, but when that beam moves elsewhere, it takes some time for the previous point to fade to black. Furthermore, if the beam is quickly moved across an area, the whole path of the beam will be illuminated and will only slowly fade back to black. We'll have to be careful to replicate that persistence when we digitally recreate the effect.

Different physical instruments can produce the same note but still sound different, because they have different timbres. With synthesizers, musicians were able to create completely new sounds, without the need of a physical source of vibrations.

A sound or music is said to be stereo when it is made up of two distinct signals, also called channels, one for the left ear and one for the right ear. This is where we can start to understand the origins of oscilloscope music.

Indeed, oscilloscopes are used to show electrical signals on a screen, and they can be controlled by two signals at the same time, one for the x axis and one for the y axis. Those two signals control the position of the dot on the screen, but because this dot moves really fast, it is seen as a single continunous line.

The project explores the missed possibilities of a (quasi) dead analog screen technology, while at the same time pushing for a completely different way of synthesizing audio signals. Together with the album, the custom application "OsciStudio" was also released. It is a synthesizer that connects to the 3d modelling application blender to generate sounds which, when played into an oscilloscope, generate the 3d model.

Thankfully, nobody told [Mark Hughes] that his digital scope would make a lousy X-Y display, so he just plunged ahead and figured out how to make it work anyway. The results are actually pretty good, but it took some doing. His setup begins with OsciStudio, an application built to take 3D shapes and animations and turn them into oscilloscope music. The output from that is piped to a USB sound card; [Mark] used a PreSonus Studio 26c, an adapter with DC-coupled inputs, which he found to be critical to getting good images. Also important was a USB isolator and good-quality cables, which greatly reduced jitter and made the image much more stable.

Plonat Atek is a digital game that communicates itself to the player only via the stereo headphone

jack. The signal is split, and one of the streams is fed into a pair of headphones that show the game

to the player as a melody, interlaced with a series of blips and bursts of noise. The other stream

leads into an oscilloscope, that visualises the two channels by moving a dot across the screen in

correspondence to the signal. On the screen, the game manifests as a ball bouncing around in a

circular version of Breakout.

Both the oscilloscope and the speakers are analog devices that interpret the signal and generate a

representation of the game. The representations are based on interrelated properties of the same

signal. Thus, the relationship between the audio and visual components is not merely designed,

rather the two emerge from identical information: In Plonat Atek, the sound is designed to be seen

and the visuals are designed to be heard. For example the blip heard when the ball bounces is the

distortion seen in the same moment, and the noise heard when the ball is lost is visible as a glitch
