How To Create Music Visualizer?



Music Visualizer
This musical visualizer provides an excellent way to add more depth to the experience of music and is very easy to build. It can also be useful as an actual oscilloscope for some applications.

What you will need:
• an old CRT (almost all the work of b & w tv)
• some wire-band and pliers
• A bit of wire and an amplifier of some kind
• music to run threw zed amplifier
• basic electronics skills are helpful

It can work in two ways, depending on how it is configured, a horizontal line that is bent in waveforms, and a point that expands into a crossed circle. If you think you don’t want to make it by yourself then you can get it readymade.

Step 1: The TV

AB & W TV should be easy to purchase on a yard sale, thrift store, maybe in someone’s garbage, or probably somewhere in your house. It seems like most all b & w TV works, but I have reported on color TV works (I’ve tried two to no avail), even a computer monitor can work to the scorcher.

Carefully open your TV. You should see a significant glass tube with a large circuit board underneath. At the end of the tube near you look at some wires coming out of the hose connected to the board (leave them alone), but in front of them, you should see thick coils of cables against the pipe and four wires that come out in the vicinity of these coils. Somehow grouped in two on each side.

Be careful because capacitors on the control board can store massive charges for days and the tube acts as a high voltage capacitor in most cases not fatal, but do not take the chances of its still possibly deadly.

Step 2: Cut and hook it up

Cut one of these four wires identified in the last step then turn the TV back on if you get a vertical line, then cut one of the horizontal coil wires. As you have guessed, a horizontal line means that you cut the vertical coil

Well, what you want to do is to put one of the coils with the wires that went to the vertical loop (the vertical supply) and put music in the other coil.

The most comfortable and most likely work to do would be to put the vertical supply suspended to the vertical coil and put the music in the horizontal coil.

But you could hook the vertical supply up to the horizontal coil for a more extended line I think that looks better, but on my newer that did not work. It’s hard to say how much less likely this is to work. Statistically, it has a 50/50 chance it only depends on the TV you can give it a try if you want.

Also, you could hook up both coils to your sound source for a point that expanded into a squiggly circle, as I said in the introduction and I did like it so much.

If you use horizontal supply, use a flat line that moves up and down with the music, which is pretty boring. This happens because the parallel supply operates at a much higher frequency and pulls the electron beam back and forth so fast that the music doesn’t have any time to move it before it has already crossed the screen.

Hopefully, you can solder wires isn’t necessary; you can easily twist the wires together. Taping over your connections is a good idea for insulation, but I didn’t even do that to make sure your cables aren’t in contact with anything when doing your case (or if you test it).

Once you have it, as you run it wires from the coil (s) you’re putting music in so you can close it until the fall of each wire gets speaker wire or whatever just put it somewhere on the edge of the case as you seal it again and it will take place.

Step 3: Insert the music

The Visualizer is a different speaker for any amplification of your use you may not want to use your most expensive amplifier
An average stereo or a guitar amplifier should be nice or an amplifier of some computer speakers to do.

Put the coil in series with a speaker on your system, if the volume needs to be so far as to move the line decently put the coil parallel to the speaker.

Step 4: More info

You will get a constant set of graphs of something like 1 to 0.1 milliseconds of the vibration of the music.

The vertical supply pulls the beam across the screen 100 to 1000 times a second the exact frequency depends on the TV. When the laser crosses the screen, the music signal efficiently pulls up and down the waveform of the audio (at 100 to 1000 Hz (times per second)) to give you a dynamic view of sound hopefully that’s a decent explanation.

And get a pretty useful scientific tool from the looks of it, too much big scary orbit for me.

A few ideas (no, you do not have to follow this), you could adjust the volume potentiometer to the output, build your driver (sawtooth), if the driver orbit on the TV refuses to work, like it on one Color TV I tried, With a color TV you may use a band-filter and have the wave change colors depending on the frequency. If the driver circuit refuses to work, maybe a dummy load (resistor) across the horizontal drive would solve the problem (I think that was as well from a comment). On specific TV’s you may be able to twist the plastic that coils the deflection to a horizontal line and also have fun with your oscilloscope audio-visualizing thing.

How Many Decibels Is A Really Loud Speaker?



loud speakers
Have you ever asked yourself what makes a speaker really loud? No matter if you are a music enthusiast or a home cinema fan, in order to have a great audio experience it is important to understand the science behind decibel levels.

In this article, we are going to explore the world of decibels and reveal the secrets of really loud speakers. We will also guide you through the factors you need to take into consideration before you buy your loudspeaker. So, let’s get started!

What Are Decibels?

Before we start talking about loudspeakers it is important to understand the measurement units used to express sound levels – decibels (dB). Decibels are units that measure the intensity of sound. There is one thing you should know – when you increase the sound by just 10dB the loudness of the perceived sound doubles. This is the reason why just minor changes in the decibel ratings can have a great impact on your listening experience.

What Decibel Range Is Considered Loud?

To make it easier to understand this we have made a short list of the common sound levels and then the number of decibels for each:
• Whisper: 30 dB
• Normal conversation: 60 dB
• Vacuum cleaner: 70 dB
• Lawnmower: 90 dB
• Live music concert: 100-120 dB
• Jet engine at takeoff: 140 dB

As you can see, the sound levels can vary significantly. A speaker producing 100 dB or more is typically considered loud, however, this can be different depending on the person listening.

What Is The Decibel Level For A Speaker To Be Considered Really Loud?

A really loud speaker typically produces sound at a level of around 100 decibels (dB) or higher. Decibels are a unit used to measure the intensity of sound. For reference, normal conversation is about 60 dB, while live rock concerts can reach 110-120 dB. Keep in mind that prolonged exposure to sounds above 85 dB can cause hearing damage.

How Do Loudspeakers Work?

Loudspeakers transform electrical signals into sound waves by using a diaphragm to vibrate and produce sound. In simple terms, the larger the diaphragm and the more powerful the amplifier driving the speaker, the sound output will be higher.

So an essential factor to determine the loudness a loudspeaker can produce is the decibel rating.

What to Look for in a Loud Speaker

Before you buy a loud speaker system it is important to take the following factors into consideration. This should help you get the right level of loudness.

Speaker Sensitivity

Measured in dB, speaker sensitivity indicates how effectively a speaker can convert power into volume. Speakers that have higher sensitivity will use less power to produce more volume. On average the sensitivity will be around 85-88 dB. However, a sensitivity of 90 dB or higher is considered excellent.

Amplifier Power

The speaker will be louder if you use a more powerful amplifier. Make sure that the wattage output of the amplifier is compatible with the power handling capacity of the speaker you want to buy.

Room Size

Another factor that plays an important toe in determining the appropriate loudness is the size of your listening space. You will need a more powerful speaker if you are going to use it in a large room. This will help effectively fill the space with sound.

Listener Preferences

Take your own listening habits and preferences into consideration. If you prefer to listen to music at higher volumes or you want an improved home cinema experience. You are going to need a speaker system that can produce higher decibel levels.

Understanding the Risks of Excessive Sound Levels

Although loud speakers can improve your listening experience it is important to understand the risks associated with extreme sound levels. Being exposed to sounds above 70 dB for a longer period of time can result in permanent hearing damage. Therefore, you need to practice safe listening habits all the time and use hearing protection when necessary.


In the end, we have to say that it is really important to understand the science behind decibel levels. This can help you improve your audio-listening experience. As for the decibels, the most important thing to know is that even minor changes in the decibel rating can significantly impact your listening experience.

If you plan to buy a loudspeaker make sure to take the following factors into consideration: speaker sensitivity, amplifier power, room size, and your own listening preferences. While loudspeakers can enhance your listening experience, you have to be aware of the negative effects of prolonged exposure to excessive sound levels. If necessary, consider using hearing protection or just start practicing safe listening habits. This should help you enjoy your music or home cinema audio with optimal loudness and safety.

A String Of Differences: The Cello vs. The Double Bass



cello vs double bass
When it comes to stringed instruments, the cello, and double bass may seem quite similar. After all, both are played with a bow and have a distinct deep sound. However, some key differences between the two instruments set them apart from each other. In this blog post, we’ll explore the differences between the cello and double bass, including their size, sound, and technique. Whether you’re an aspiring musician or simply curious about the differences between these two instruments, read on to learn more!

What is the cello, and in what musical directions does it occur?

The cello is a string instrument from the violin family and is usually the highest-pitched string instrument in an orchestra or string quartet. It has a deep and sonorous tone and is often seen as the ‘soul’ of an ensemble. The cello produces sound by drawing a bow across four strings, tuned to the notes C2, G2, D3 and A3.

The cello can be found in almost all styles of music, from classical and orchestral pieces to pop and jazz. It is an extremely versatile instrument, being able to move easily between different genres and settings. Its sound can range from beautiful, haunting melodies to powerful and driving rhythms.

If you are interested in learning the cello, there are many avenues you can take. There are dedicated cello teachers who offer one-to-one tuition in the instrument and group cello classes that teach you the fundamentals of playing. Alternatively, if you prefer to learn on your own terms, plenty of online tutorials are available. Cello lessons are available for those looking to get a deeper understanding of the instrument, which will help develop your skills further.

No matter how you decide to learn, the cello is a rewarding instrument to master. With a little bit of practice, you, too, can be on your way to mastering its wide range of sounds!

Comparison of double bass and cello

The cello and the double bass are both bowed string instruments. The main difference between them is the size, as the cello is much smaller than the double bass. The cello is a four-stringed instrument with strings tuned to the same four pitches as the viola. It is usually played in the sitting position, with the cellist’s feet placed on a footstool. Meanwhile, the double bass is a much larger instrument with four or more strings, generally tuned to an octave below the cello. It is played standing up, typically using a strap over the shoulder for support.

In terms of sound, the cello has a more melodic tone, while the double bass tends to provide more of a rhythmic foundation in a musical ensemble. The cello also offers more soloistic possibilities due to its higher range and melodic capabilities.

In terms of playing technique, the cello uses fingering and shifting, which allows for faster playing. Meanwhile, the double bass has more of a rhythmic focus, so it often utilizes bowing and pizzicato techniques.

If you’re interested in playing either of these instruments, you can find a private teacher or take cello private lessons near me at your local music store. Private cello teachers will be able to guide you through learning the basics of playing the instrument and eventually teach you how to play all types of music, from classical to pop and jazz. You can even take cello music lessons online if you don’t have access to an instructor locally.

Why learning to play the cello is easier for beginners

For many musicians, the cello is seen as an easier instrument to learn than the double bass. While both instruments use strings and a bow to create music, some key differences make playing the cello a great choice for beginners.

Firstly, the cello is smaller and lighter than the double bass. This makes it easier for beginners to maneuver, particularly young students in beginner cello lessons for kids. As the cello is held upright, it is much easier to adjust the posture and find a comfortable playing position than with the larger and heavier double bass.

Secondly, the strings on the cello are thinner and lower in tension than those on the double bass. This means that beginners can produce a beautiful tone without putting too much effort into their bow stroke. This also enables them to learn techniques like vibrato and pizzicato more quickly.

Finally, the fingering patterns on the cello are much more logical and easier to remember than those on the double bass. The positions of the notes on the fingerboard remain consistent regardless of what key you are playing in. This helps to build muscle memory more quickly, enabling beginners to quickly progress through beginner cello lessons.
For these reasons, learning to play the cello is often considered easier for beginners than learning to play the double bass. Whether you are looking for beginner cello lessons for kids or adult classes, choosing the cello will give you a great foundation in music theory and performance.

In conclusion, it’s clear that the cello and double bass are two unique instruments. Each has its own range of tones and notes, as well as its own distinct style. Cello lessons Toronto offer cello classes for all ages, from kids cello lessons to cello lessons for adults, making it the perfect instrument for any musician. Whether you’re a beginner or a professional, the cello is a great choice for mastering the art of string playing.
