I would like to have the option of speeding up audio when I listen to audio books. Typically i would add the following to the ffmpeg command:
- Code: Select all
-filter:a "atempo=1.5"
in order to speed the audio up 50%. When I tried to create a new transcoder, I used the following:
- Code: Select all
ffmpeg -i %s -filter:a "atempo=1.5" -map 0:0 -b:a %bk -v 0 -f mp3 -
However, after I click save, the command saved is only this (nothing after the first quote):
- Code: Select all
ffmpeg -i %s -filter:a
I tried using atempo=1.5 without the quotes, but the audio played at normal speed. Just wondering if anyone has successfully done what I am trying to do (even if you've used something besides ffmpeg, I'd be interested). I'm running subsonic on a RaspberryPi 3.
Here's what I tried step by step:
1. Created a new transcoder with the -filter:a option shown above
2. Created a new player
3. Assigned only my new transcoder to that player
4. Selected the new player and sent audio to that player
