Earlier in the week I took time to work on the transfer functions for the Distortion effect. The standard way to achieve an overdriven sound comes by passing the samples into an arctangent function which you can see in the following code snipped, The first two commented lines are the original arctangent functions and the rest are test I performed on several other transfer functions.
I tested different sounds as well as adding a sine term to the wave which showed promising results for the distortion itself.
the wave with full distortion can be seen in this demos graph in blue, the purple waveform is the original distortion function done last week and the red graph is the input sine wave:
The distortion function I made showed a flatter response on the peeks compared to the original transfer function tested last week. A sample test of the original distortion sound can be heard here: https://static.wixstatic.com/mp3/f9d080_806e78a820304751b535648f57154b5f.wav
once the new transfer function is ready it will be also included in an upcoming progress log.
This week I also worked on chapters 1 and 2 of the report
