Split a 4 minute WAV file into 5 second WAV file parts software needed

[barry25]

Hi I need some help with this question if anyone can help me with this

Does anyone know of any software that will split and convert like a 4 minute WAV file to a 5 second WAV file parts. I have got some WAV files that are like 4 minutes long of sounds and what I want to do if it can be done is can I split and convert like a 4 minute WAV file into parts like 5 second WAV audio files parts. I can do this manual with AudaCity but doing this with like over 50 WAV 4 minute files would take ages to do I know that when you convert video files you can leave a software to convert a load of video files but this is audio files. and I want to split like a 4 minute WAV file into like 5 second wav files is there any software that will do this instead of doing this manual file by file. like is there a converter we’re you put in like how long you want your audio file to be and it splits it into parts I don’t know of any software that will do this only doing it manual with audacity one file at a time which does take ages to do any help will do.

I'm not good with this type batch file. So I'm not going to attempt it.
I believe FFMPEG with the correct batch file can do this.
Maybe a forum member that is can help you with one.

Something like:

ffmpeg.exe -i input.wav -codec copy -f segment -segment_time 5 -reset_timestamps 1 "output%%03d.wav"

"reset_timestamps 1" may not be necessary.

If you have a lot of files, create a batch file (.bat in the folder with the files). It will check the entire folder for wav files, cut each of them into 5-second fragments, and place them in separate folders.

@echo off
setlocal enabledelayedexpansion
for %%f in (*.wav) do (
    set "filename=%%~nf"
    mkdir "!filename!" 2>nul
    ffmpeg -i "%%f" -f segment -segment_time 5 -c copy "!filename!\!filename!_%%03d.wav"
)

p.s. and put in the folder ffmpeg.exe if it is not in your PATH

Hi LISTYDOM How DO I CREATE A BATCH FILE THEN I have got over a 100 WAV audio files how do I do that then

I just wanted to test the codes.
I could not get either the code or the .bat to work.
I need a better guide & I believe the OP does too.

It seams to work, as was explained
-put ffmpeg.exe into windows PATH or into the folder where wav files are
-create bat file, by creating a txt file in notepad, paste that posted text and rename it to something.bat, put that bat into folder where those wav files are
-run that bat by double clicking it or right click it and press Run

but I'd recommend to tweak ListyDoM script to just call a function instead of using enabledelayedexpansion, it is a good habit to call functions.

@echo off
for %%f in (*.wav) do call :split_wav_files "%%f"
echo press any key to exit&pause>nul&exit


:split_wav_files <some wav file which becomes %1 in this function>
set "filename=%~n1"
mkdir "%filename%" 2>nul
ffmpeg -i "%~1" -f segment -segment_time 1 -c copy "%filename%\%filename%_%%03d.wav"
goto :eof

@ _Al_,
The Code you posted worked fine.
I did change the -segment_time 1 to -segment_time 5 to get the 5 seconds the OP wanted.

The code or script ListyDoM did not work foe me.

If there is "!" character in names, it does not work, if using enabledelayedexpansion, otherwise not sure what is going on.
