ffmpeg FLAC 24 bit 96khz to 16 bit 48khz

问题

Trying to figure out ffmpeg, currently working on getting 24bit/96khz FLAC files into 16bit/48khz.

回答1:

ffmpeg -i input.flac -sample_fmt s16 -ar 48000 output.flac

---

• List sample formats: ffmpeg -sample_fmts
• List additional flac options: ffmpeg -h encoder=flac
• See FFmpeg Resampler Documentation for additional resampling options including available dithering methods.

回答2:

As a bash script, that produces new files with -16 appended to their names; one could rename then delete the original files easily in the script but I'm a little too paranoid for that.

#!/bin/sh
# requires: ffmpeg
for f in *.flac;
do
echo "Processing $f"
ffmpeg -i "$f" -sample_fmt s16 -ar 48000 "${f%.flac}-16.flac"
done
