For those that know a little scripting and know about Sox… here’s my little script that splits files into 2 minute chops and converts the result to the s2400 default sample rate and bit depth. Maybe you can use some of this to create something similar for yourself…
@ECHO OFF
echo Splitter start
call :treeProcess
echo Splitter done
goto :eof
:treeProcess
call :splitAndConvertProcess
for /D %%d in (*) do (
cd %%d
echo dir: "%%d"
call :treeProcess
cd ..
)
exit /b
:splitAndConvertProcess
mkdir tmpSoxxx
for %%f in (*.wav,*.flac,*.mp3) do (
echo splitting file: "%%f"
"C:\Program Files (x86)\sox-14-4-2\sox.exe" -V1 "%%f" "tmpSoxxx\%%~nf_.wav" trim 0 120 : newfile : restart
del "%%f"
)
cd tmpSoxxx
for %%f in (*.wav) do (
echo converting file: "%%f"
"C:\Program Files (x86)\sox-14-4-2\sox.exe" -V1 -G "%%f" -b 16 -r 48000 "..\%%f"
del "%%f"
)
cd ..
rmdir tmpSoxxx
exit /b
