Dear smart friends, I have a question about sonification. Can you advise me how I can convert human movement recorded by inertial sensors into sound? Is there any available program/application to download or purchase? Thank you very much.
Hi Miriam,
Assuming that by "recorded" you mean "digitized", you can generate *.wav sound files from the 'motion' waveform you have recorded, using Python and appropriate packages for example (https://www.quora.com/How-do-you-create-an-audio-and-waveform-generator-with-Python).
Now, to be audible, your 'motion' waveform might have to be subjected to some transformation for the generated sound signal to fall in the human ear frequency range (signal processing can be done in python as well.
). You will find an example of transformation in this publication (Article If motion sounds: Movement sonification based on inertial sensor data
), but there are many others available online for other applications (Article A method to convert neural signals into sound sequences
).
Hi Miriam Kalichová ,
This is a very interesting topic, and something which I have recently been experimenting with with my own mass spectrometry data.
If your data consists of two numeric vectors, you can easily convert it to tones using what is essentially a reverse Fourier transformation. I have built a web application where you can try this out:

If you're familiar with coding, I've done a bunch more in R. You can find my code here:

I'd be happy to talk in more detail if you like, or help adapt my code to your data. Feel free to message me on ResearchGate, or you can email me at [email protected]
All the best!
Sam
