Sorry for the delay in responding.

1) All I did was replace the existing ChangeTemp.cpp code with my .cpp code
.
I complied the code and binary file was present in the same folder .
Then I restarted Audacity to see the changes , unfortunately there was no
changes .Defnetly I'm missing something here ,Could you shed some light ?

2) I would have to discuss with my advisor to share the code with the team
,kindly excuse for a while .(I'm waiting for my Proff's reply , would be
able to update you on that soon enough).

In my algorithm for time scaling , Upon running I need to enter a factor
between* 0.5 - 2  *. 0.5 factor would scale down the speech signal and play
the signal at a slow rate , while factor 2 would would speed up the speech
signal .
In Pitch scaling : Similarly enter the factor between *0.5 -2  *, 0.5 would
change the pitch to a male voice (more base ) while factor 2 would result
in a higher pitch resembling a female voice .
PFA of the audio files .
The only input to my code is a input speech signal and a scale factor.

3) I use Linux 16.04version , To compile my .cpp code I use gcc , with two
depended libraries (armadillo and libsndfile)
