LabChirp : Generates Sounds for Your Own Projects

Have you ever wondered how the small sounds in the older computer games were created? They were created simply by combining sound waves of various frequencies. You can hear these sounds in games like Super Mario or Wolfenstein 3D. If you want to generate these types of sounds for your own projects then you can use a free tool called LabChirp.

LabChirp can create sounds of multiple frequencies along with frequency and volume modulations. By changing the value of frequency and amplitude of the main wave and the modulation, you can have virtually an infinite number of resulting sound waves. On top of this, you can choose a waveform type for the main wave, frequency modulation and the volume modulation. You can choose all types of waveforms like sine, triangle, sawtooth, square and more. And as if this is not enough, you can have eight different channels for these generated sound waves – when played together they make a completely unique sound.


If you do not want to go through the pain of manually selecting the frequency and volumes for creating the sounds, then you can use the Randomizer and Mutator tools. The randomizer tool, as expected, can create a random wave using a number of random combinations – a new sound every time you click on the Randomize button. Once you have a sound that you like, you can use the Mutator to slightly change the sound – slight variations every time you click on the Mutate button.


If you are a fan of the original Star Wars movies (made between 1970s and 1990s), then you will instantly recognize how similar the sounds generated by LabChirp are with the ones in those movies. Back in those days, they used a battery of electronics instruments to generate those sounds. But now you can create similar sounds in your PC using LabChirp.
