[solved] ffmpeg on multiple .aac files in directory using find - Sprintrdriver - 08-06-2019

Hi.

I have a folder with multiple .aac audio files. I plan to use them in a car stereo that is very picky on accepting files.

So I found out using ffmpeg to clean out any unused metadata and possible other non-auditible information using this command:
ffmpeg -i 'input.aac' -vn -c:a copy 'output.aac'

I want to be able to do this for several files at once. According to [url=http://"https://unix.stackexchange.com/questions/80851/how-do-i-run-a-command-on-multiple-files"]this thread in unix.stackexchange forum[/url], it should be easilly done by using the find command.

However - I have tried several variation of the command (using the example from unix.stackexchange forum), but without any success (ffmpeg claim error about file existing). This is the commands I have tried so far:

Code:
find . -name "*.aac" -exec ffmpeg -i {}  -vn -c:a copy 2_{}

find . -name "*.aac" -exec ffmpeg -i {}  -vn -c:a copy 2_{} \;

find . -name "*.aac" -exec ffmpeg -i {}  -vn -c:a copy NEW{} \;

find . -name "*.aac" -exec ffmpeg -i {}  -vn -c:a copy NEW{}\;

find . -name "*.aac" -exec ffmpeg -i {}  -vn -c:a copy NEW{} \;

find . -name "*.aac" -exec ffmpeg -i '{}'  -vn -c:a copy 'NEW{}'\;

I usually got an error message like this (for every file):
NEW./input-file-name.aac: No such file or directory

I cannot 'see' the command that ffmpeg actually receive, so I cannot tell if there is an obviously error.

Update:

I have got help on this on a local forum. I didn't get a solution that I could just enter directly in Terminal, but I got help with a sample shell script that I managed to:

Run ffmpeg on all files in current dir
Using touch command to set tate for converted files similar to the original file
Renaming files so that the original files change the name.

Code:
#!/bin/bash

for i in *.aac

do

    echo ""

    ffmpeg -i "$i" -vn -c:a copy "NEW_$i"

    touch -cm --reference="$i" "NEW_$i"

    mv "$i" "OLD $i"

    mv "NEW_$i" "$i"

    echo ""

done
