Questions about preprocessing methods

[2018161062Jiseong]

Is there a big difference between using the Combtooth subtractive synthesizer method and the Sinusoids additive synthesizer method in the preprocessing process? If so, which one produces better results?

There is no difference, the audio quality is also close (both are worse, if no enhancement method is used), but the CombSub model trains much faster than Sins.
