I have 10 wav-Files. I want to convert all of them into mp3-Files. I managed to to this for one single file (as described in How to convert media using VLC?), but I don't want to do this for every single file. Is there a way to convert all the 10 files at a single blow? I'm using windows 7.

I followed nixda's suggestion and used a batch script. I figured out how to programm a batch for windows 7. This is my solution:

@echo off
for /f "delims=|" %%f in ('dir /b C:\Any_Directory\*.wav') do (
echo converting      %%f
CALL "C:\Program Files\VideoLAN\VLC\vlc.exe" --intf dummy --dummy-quiet "%%f" --sout="#transcode{acodec=mp3,ab=256,vcodec=dummy}:standard{access=file,mux=raw,dst=MP3_Files/"%%f"}"  vlc://quit
move "%%f" WAV_converted/"%%f"

cd MP3_Files
ren *.wav *.mp3
cd ..

echo .
echo .
echo .
echo conversion finished

How the programm works:

  • All the files with the .wav extension in the specified folder "C:\Any_Directory\" are converted to mp3
  • The mp3 files are saved in the folder "MP3_Files" (which must already exist)
  • The wav files are pushed to the folder "WAV_converted" (which must already exist)
  • "ab=256" sets the bit rate. To convert with e.g. bit rate 128, replace it with "ab=128".
  • The batch file must be run from the same folder as the files you want to convert ( as mentioned by Kevin Heidt )

Hints - Remove "--intf dummy --dummy-quiet" from the script if you want to see the VLC GUI while converting. Could be useful for debugging.

Update There ist still one bug: If the name of the wav-file contains a dot or comma, the name is truncated (and no extension is appended!). The file gets converted despite this. Tested with Version 1.1.11. Newer versions may not work!

Added quote sign: --sout="...". Works for newer Versions, too. Tested with Version 2.1.3 64-bit on Windows (see for differences in command line for Linux and Windows).

+1 Good & new solution –  nixda Jul 16 '13 at 7:41
Note: this assumes your batch file is being run from the same folder as the files you want to convert (D:\"folder xyz"\VLC_batch) –  Kevin Heidt Sep 16 at 17:40
excellent stuff. –  roel 2 days ago
