hello, I made many comparisons and to my ears audacity's pitch shifting
engine sounds the best. I would love to make a cmd and bat file for the
pitch shift without length change. As that sadly isn't possible in
audacitys limited command line access I was curious if tenacity would be
up for something like that. here is an example

@echo off
set PATH="C:\Program Files\Tenacity"
set TENACITY=%PATH%\tenacity.exe
set INPUTFILE=%1
for /F "delims=" %%i in (%INPUTFILE%) do SET BASENAME=%%~ni
@REM  >>>> Change pitch without changing tempo +4,271% aka +0,72
semitones aka 72 cents <<<<
"%TENACITY%" -i %INPUTFILE% pitch +0.72 %1%-pitch-correct.wav

thanks in advance for your help

regards

-Hendrik
