How to change sample rate of bulk .wav files with bash script?

[taersh]

Hi.

I want to change the sample rate of a bulk of .wav files from 48000 to 44100. How can I do this via bash script and e.g. ffmpeg?
Perhaps there's something other/easier to use than ffmpeg?

Thanks

If your pup has Menu -> Multimedia -> FFConvert multimedia converter, I'd say look into it. The UI takes some getting used to but I think you'll be able to do what you want with it. There are several other Puppy programs that might work. I think they all use ffconvert. Multimedia -> mhWaveEdit is a very powerful program. You drag the file you want to change into its window, then play around with it.

Thanks, but no. I don't have FFConvert installed.
Where to find?

Thanks.
I have QWinFF installed and it does what I want.
But I still would like to know how to do this via bash script and ffmpeg (or whatever tools are there).

(or whatever tools are there).

Maybe then SoX. "Swiss Army knife of sound processing". Old but good. It is in PPM. Something like:

Code: Select all

sox input.wav output.wav rate 44k

You can use ffmpeg commad line tools to change sample rate of .wav file

ffmpeg.exe -i "Audio Input FilePath" -b:a 64k "Audio Output FilePath"

ffmpeg.exe -i "Audio Input FilePath" -b:a 64k "Audio Output FilePath"

Hi. First, you seem to be used to Windows Secondly, even if you remove the .exe, it will hardly work. The starter of the topic says about sampling frequency (Hz), and you have bitrate (kbit/s).

Therefore, the command should be like this:

Code: Select all

ffmpeg -i test.wav -ar 44100 test1.wav
