Why Do You Need an Oscilloscope for Car Audio?

The basic function of a stereo oscilloscope is to provide a visual representation of the variations in sound amplitude in the music (in relation to the time). Simply put, an Oscilloscope can display the change of intensity of sound in a graphical manner. Therefore, you can use this tool to do synthesis and dynamics processing in music. Also, sound engineers use oscilloscopes to reduce external and foreign noises from a certain music track.

And, if you have a large audio system in your car, you would want it to provide a crystal clear audio playback, right? That’s where the Oscilloscope comes in. An Oscilloscope can easily provide you with the capability to set up your gains in the music and tune your music playback according to your will.

Furthermore, as an oscilloscope displays the amplitude of the music sounds through voltage signals on a display, you can easily visualize and understand how intense your car audio system can perform. This way, you can take the best advantage of your car audio system and use it with its full efficiency without losing quality on the music playback.

Benefits of Using Audio Oscilloscope

There are multitudinous benefits of having an audio oscilloscope in your music system. In case you are a music enthusiast, you should have a crystal clear idea of how an oscilloscope can make a difference in your music playback. Therefore, let’s go over the benefits of using an audio  oscilloscope:

  • Perfect noise cancellation: An audio oscilloscope can easily detect and display unnecessary noises in audio recordings. That’s why it is used to produce noiseless music in the music industry.
  • Crystal clear sound production: Since an audio oscilloscope can monitor even the slightest variations in the sound, it can be easily used to produce music tracks without any noise or distortion. As a result, audio oscilloscopes make an excellent tool to produce ultra-clear music.
  • Auto tuning boost up: In the music industry, many artists use auto-tuning softwares to polish their music recordings. And, in the process of auto tune-ups, an audio oscilloscope can massively help by providing all the necessary data from raw music tracks.
  • Powerful recording: Another benefit of using an audio oscilloscope in the realm of music is that it can provide the necessary boost up in the audio volume in a particular recording. For example, if you have a sound recording that has very low sound volume, you can take advantage of an audio oscilloscope to monitor the existing sound volume and increase it according to your needs.
  • Easy audio monitoring: Other than all the benefits we have mentioned above, you can also use an audio oscilloscope to simply monitor a certain soundtrack or audio. This can be useful in music recording, speech recording, video editing, etc.

What To Consider When Buying The Best Oscilloscope for Car Audio [ Buying Guide]

Since there are hundreds of models of audio oscilloscopes in the market, you might get baffled when you are setting out to buy one. That’s why we are here to help you out. In this section, we will tell you about what things you have to look out for before buying the best oscilloscope for your car audio.

What To Consider When Buying The Best Oscilloscope for Car Audio

Don’t worry, you don’t have to put too much effort in order to find a high-quality product. All you have to do is thoroughly read this guide till the finish line:

Analog Or Digital?

In the manufacturing industry of oscilloscopes, 2 types of audio oscilloscopes are prevalent. Analog and Digital. While old-fashioned engineers use analog audio oscilloscopes, modern sound engineers always like to take advantage of digital ones.

And, our recommendation also resides with the digital option. If you buy a digital audio Oscilloscope (rather than an analog one), you can rest assured that your audio oscilloscope will have the following benefits:

  • Extremely portable
  • Compact in size
  • Will have a higher range of bandwidth
  • Will have vibrantly colorful displays
  • It May have the simplest user interface
  • Will support software modification
  • Storage of numerous reports and instant printing

Therefore, if you want to be proficient in your duty as a sound engineer (or a sound technician), you should go for a digital audio oscilloscope.

The Range Of Bandwidth

When buying an audio oscilloscope for your car, the bandwidth range is the first and foremost criteria that you have to pay attention to. The bandwidth range indicates how high and low limits the sound volume the audio oscilloscope system can work with.

Not only that, the bandwidth range defines the maximum frequency of sound levels your oscilloscope will be able to measure and calculate. That’s why you always have to choose an audio oscilloscope that has a higher max frequency bandwidth than the audio frequency you want to test and modify.

For example, if you are working with 1500 megahertz sounds, you must have an audio oscilloscope that can support a higher magnitude of frequency than 1500 megahertz.

The Sampling Rate

After the bandwidth range, the next most important aspect of an audio oscilloscope is its sampling rate. Monitoring the sampling rate is a great way to detect and modify the nuances in the music and audio.

As the sampling rate is calculated in mega samples per second (MSps), you should check whether your oscilloscope has the capability of displaying sampling rates.

Also, you need to make sure if the oscilloscope you’re choosing has the right sampling rate that you want or not. While some oscilloscopes will have single-channel mode, others can have dual channel sampling modes. Depending on your needs, you must be decisive here to pick an option according to your needs.

Memory Depth Of An Audio Oscilloscope

Although many people don’t have a clear idea about the memory depth of audio oscilloscopes, it is mandatory to have a comprehensive idea on this topic (if you want to pick a good quality oscilloscope for yourself).

The memory depth is the buffer memory that stores the signals that are produced by audio inputs. The memory depth also indicates how long an audio oscilloscope can capture and show audio signals.

That means, if you have a higher memory depth, you’ll have fewer disturbances in monitoring and modifying long audios. That’s why our recommendation is that you choose an audio oscilloscope that has the highest memory depth.

The Resolution Of The Audio Oscilloscope (And Accuracy)

You have to understand that, in the realm of sound engineering, even 0.1% distortion in the soundtrack can cause disastrous effects. For example, if you have even 0.1% noise in your recorded songs, this effect will disturb the listeners.

As a result, the production of music can be really harmed by audio distortions. And, in order to prevent audio distortions, you’ll have to use audio oscilloscopes. Now, if the resolution of your audio oscilloscope is not high enough, it won’t be able to detect the most subtle noises in an audio.

For instance, most audio oscilloscopes in the current market will have 8-bit resolution . However, if you have a 12 or 16 bit resolution in your audio oscilloscope, you’ll have higher capability of monitoring audio with even higher precision. That’s why we recommend going for a high resolution audio oscilloscope.

The Form Factor ( Size And Shape)

As an audio oscilloscope is an electronic device, it has a certain weight and shape that can either be handy to carry or be a dead weight. That’s why you need to choose a perfectly sized audio oscilloscope for your car( that is both lightweight and highly capable).

Now, for your information, audio oscilloscopes come in 3 types of form factors: Bench-top, Handheld, and Computer-based. Among these 3 types, we recommend going for a digital handheld audio oscilloscope.

Frequently Asked Questions

Is it safe to buy a used oscilloscope?

Ans. Yes, it’s perfectly fine to buy a second-hand oscilloscope if you know how to test and check all the needed parameters of an audio oscilloscope. Simply put, the risk of buying a second-hand oscilloscope completely depends on your expertise.

For instance, if you know the ins and outs of audio oscilloscopes and are able to check the second-hand oscilloscope thoroughly before the purchase, it is safe for you to buy a used oscilloscope. On the other hand, if you don’t have that kind of expertise, we recommend going for a new one.

Who invented the oscilloscope?

Ans. The invention of oscilloscopes was not the endeavor of a single man. The Oscilloscope was created from a cathode ray tube.

To be more specific, an engineer by the name of Ferdinand Braun developed a cathode ray oscilloscope in 1897 for the first time. However, the development of cathode ray tubes was an endeavor backed by many other scientists from the 1800s.

Can I increase the memory capacity of oscilloscopes?

Ans. Unfortunately, you cannot modify or change the memory capacity of an oscilloscope. As the Oscilloscope is an intricate piece of electronic machinery, it is not safe for general people to tinker with it.

That’s why it is practically impossible for you to increase the memory capacity of oscilloscopes (unless the manufacturer gives the option to do so).

When can oscilloscopes be used?

Ans. Oscilloscopes can be used in many situations. For instance, you can use an oscilloscope to test and measure electrical signals and debug electrical circuits. Also, you can use oscilloscopes to monitor the variations of energy in many forms such as sound, wind, light, etc.

Can I change the resolution of the formed image on an oscilloscope?

Ans. An Audio oscilloscope takes in the sound from its surroundings and converts it into electrical voltages. As a result, any variance in the sound input manifests itself on the display as graphical spikes.

Now, if you have a highly modern model of digital oscilloscope, you will be able to change the resolution of the graphical images produced by the oscilloscope. But, in most old oscilloscope models, you won’t be able to do that.


Now that we have delivered all the needed information to you, our discussion here has come to an end. By now, you should have a sound idea of how the best oscilloscope for car audios will be.
