Hello !
What I would do (in this particular order):
1. Band pass filter from 60Hz - 12kHz
to remove DC and low freq rumbling,
If you want to optimize for Laptop speakers, you could raise the 60Hz to
200-500).
The high cut is not necessary, but speech doesnt really require much more
and you can
Hello Michael!
I've
used the peak method before but it can result in choosing a positive
side at some points and on the same basic syllable choose the negative
side because the formant filter is changing.
I seek the negative peak in the first deriviative. Depending on your recording
setup,
Hello!
Question is what you mean by resampling.
Resampling means, you go through the sample array and choose
different sampling points than the original sampling points, and
calculate values in-between, usually by using some kind of interpolation.
Now, if you choose the distance between two
Hello All!
Resampling = pitching all frequencies including Formants, resulting in
Mickey-Mouse
or Monster voice.

Use the vocal tract model, also called source-filter model, e.g. see here

Hello all!
I have implemented a multi-band compressor (3 bands).
However, I am not really satisfied with the splitting of the bands,
they have quite a large overlap.
What I do is taking the input singal, perfoming a low pass filter
(say 250Hz) and use the result for the low band#1.
Then I
