As you know based on my previous posts that i recently bought a fitbit ionic for inbuilt GPS and music player, i have been using playerfm on mobile forever, one of the nice features of palyerfm is to increase/decrease the audio speed, and i am habituated to listening at 1.2x speed, now without these option in the native ionic music player, i had to fallback on editing the podcasts on my machine by using ffmpeg.
All you have to do is run the following cmd, use the atempo parameter to adjust the speed accordingly.
ffmpeg -i input.mp3 -filter:a “atempo=1.2” -vn output.mp3
its all worth it because i don’t have to carry my mobile phone for those long walks or jogs !!
