Summary
| Description |
This image was made by me using Praat by synthesizing a waveform using some sine functions and using arctan() function to distort it. The original function is: f(x)=sin(2*pi*200*x)+sin(2*pi*400*x+0.7)*0.7-cos(2*pi*600*x)*0.3 The distorted function is: d(x)=arctan(f(x)*50)*0.3 |

Summary
This image was made by me using Praat by synthesizing a waveform using some sine functions and using arctan() function to distort it.
The original function is: f(x)=sin(2*pi*200*x)+sin(2*pi*400*x+0.7)*0.7-cos(2*pi*600*x)*0.3
The distorted function is: d(x)=arctan(f(x)*50)*0.3
