Is there a reasonable way to batch convert the bit depth of several audio files from 32 to 16?

With Adobe Audition, I can open a file, then "Save As..." and change it to 16 bit. But I have hundreds of files now.

  • It's fairly simple, depending on the software. However, do read up on 'Dithering'. – Arnoud Traa Jul 3 '14 at 5:07

In Adobe Audition there's a built-in batch processor: Edit > Batch Process

Using SoX (Windows, Linux, Mac):

cd /where/your/wav/files/are/
mkdir converted
for i in *.wav; do sox -S "$i" -b 32 converted/"$i"; done

The batch processing feature of GoldWave will do the trick. enter image description here

  • It doesn't have a dither option, I think that would be handy when converting bit depth. Does Goldwave support dithering? – Arnoud Traa Jul 3 '14 at 5:06

I love compressor for this! You can even create Drag and drop areas to Speed up the process of file conversion!
