Loop/Batch file for extracting all .aac from .m4a files in folder

I need to extract the .aac stream from ~1749 .m4a files with ffmpeg

This is what I use for single files:

ffmpeg -i example.m4a -vn -c:a copy example.acc

All loops I found on the internet aren't working for me.

Use the below examples and just plug in your source path and output path accordingly—I have both implicit and explicit examples below to run as batch or manually from command prompt.

As usual be sure to test this with test files first though to ensure it works as expected.

EXPLICIT

Manual from command line copy and paste

FOR %A IN ("C:\SourcePath\*.m4a") DO ffmpeg -i "%~A" -vn -c:a copy "C:\OutputPath\%~NA.aac"

Run from a batch script

FOR %%A IN ("C:\SourcePath\*.m4a") DO ffmpeg -i "%%~A" -vn -c:a copy "C:\OutputPath\%%~NA.aac"

IMPLICIT

Manual from command line copy and paste

FOR %A IN ("*.m4a") DO ffmpeg -i "%~A" -vn -c:a copy "%~NA.aac"

Run from a batch script

FOR %%A IN ("*.m4a") DO ffmpeg -i "%%~A" -vn -c:a copy "%%~NA.aac"
