Oi Reindl Harald,
Hi Reindl Harald,
ok, but the sample rate information is in :
Stream #0:0: Audio: mp3, 48000 Hz, stereo, fltp, 320 kb/s
What happens is that I don't know which command I use to compare only the
sample rate that is in the audio stream and manage to filter
the audio with only 48000 khz to another folder. That is, what command do I
use to read only the sample rate 48000 khz and be able to select it??
An example:
1 - Today, I have to enter the audios folder and through the mouse hint on
the file, see the sample rate and copy the file to another folder manually.
2 - After copying all the files with 48000 khz manually, I made a .bat file
to convert the sample rate from 48000 to 44100 khz and copy the converted
files to another folder, see the command below:
cd\Users\%username%\Desktop\*"Folder with 48000 khz files"*
for %%F IN (*) do ffmpeg -i "%%F" -map 0:0 -acodec mp3 -b:a 320k -ar:a
44100 "C:\Users\%username%\Desktop\*Converted*\%%F"
The bat works perfectly, but first I have to manually copy the files
to the *"Folder
with 48000 khz files"*, and that's exactly what I wanted to automate too!
Thanks
Clamarc
