Speaker Test Left Right Files for testing speakers and room acoustics

In this section, you will find a catalog of audio files, noise generators, and tone files in every tone hearable by the human ear. These are meant to be used as speaker tests, so you can test the quality and range of your audio devices. Low frequency tone files can be used as subwoofer tests. With these files, besides being able to test the quality and range of your speakers, subwoofer, home theater, headphones, earplugs, or any other audio device, you can also test the acoustic qualities in the room.

Speaker Test section

If you are testing your speakers to see if they are working correctly, you will want to test the left and right speakers separately. To do this, you will need to use our Left Right Speaker Test.

There are a few different ways that you can test your speakers. One way is to use a left/right speaker test tone. This tone will help you to identify which speaker is which.

Another way to test your speakers is to use a left/right speaker test sound. This sound will help you to identify which speaker is which by the direction of the sound.

Once you have identified which speaker is which, you can then test each speaker individually. To do this, you will want to use a left/right speaker test file. This file will help you to test each speaker individually by playing a sound through each speaker.

Once you have tested each speaker individually, you can then move on to testing the speakers together. To do this, you will want to use a left/right speaker test file. This file will help you to test the speakers together by playing a sound through both speakers.

If you are having trouble testing your speakers, you may want to contact a professional. They will be able to help you troubleshoot your speakers and get them working correctly.

Audio files for loudspeakers and subwoofers

In the Audio Files subsection you’ll find small sample files, including short speaker tests and subwoofer tests by THX. If you’d like to learn more about THX, check our THX trailers section.

Check if all your speakers are functioning properly by checking them individually. In the main speaker test section you will two wave icons (left and right) so you can test each speaker individually and note if they’re properly connected, or if your balance is properly panned.

Tones Files section

In the Tones Files section you will find audio files ranging from 20 Hz to 20 KHz. Lower frequency files are ideal to use as a subwoofer test. In the last page of the library, you’ll find sounds that go in crescendo or decrescendo. Use these files to measure the range of your audio equipment (and your own ears, also ;-))

Noise Files section

If we had to give a quick definition of noise, we’d all think of terms like “annoying”, “harmful”, “maddening”, or simply unwanted sounds. We all know what that is and how it can affect us. Deeming something as noise is highly subjective on the listener’s end. What many people probably don’t know is that noise, despite being sound waves, can also have different colors.

We can relate sound waves to light. In the same way that white light is formed by the superposition of every color and black is the absence of light and color, we can speak about the color of noise depending on the sound frequencies that form it. So, even if we can’t actually see it, noise will have one or other color depending on each of the noise’s frequency’s contribution. You can use the following Noise Files as speaker tests and subwoofer tests:

• White Noise: It’s basically random noise which is formed by a constant energy in each frequency. That is to say (as you’ll note on the wave graphic), it has a uniform distribution of frequencies. Like white light is a combination of every color, white noise is a combination of every frequency.
  
  
• Brown noise: Where white noise had a uniform energy distribution, brown noise has a descending frequency slope of 6 dB/octave.
  
  
• Grey Noise: You’ll note the graphic is convex. Grey Noise contains every frequency in equal loudness (opposing white noise which contains every frequency with equal energy).
  
  
• Pink Noise: Similar to brown noise but with a 3 dB/octave descending slope. Since every octave has double the frequencies as its previous one, this reduction results in a flat spectrum for every frequency band.
  
  
• Violet Noise: The energy distribution in this kind of noise as an ascending slope of 6 dB/octave (brown’s opposite, if you will).
  
  
• Blue Noise: With an ascending slope of 3 dB/octave, we could say it’s pink noise’s opposite.
  
  

The best part? All of these files are coded in lossless .flac format, so you can expect the maximum sound quality out of these subwoofer tests and speaker tests so you can get a glimpse of the full spectrum your audio system is capable of delivering. In Demolandia, you’ll always find the best files for testing your multimedia equipment, both for home or vehicle.
