Thought I would post this

When I play files through my car Bluetooth, they are often too quiet even with theĀ  ICE(In car Entertainment) at max and the mp3 player (My phone) at max, unless I use an application like DBamp, which isn't really tailored to audio books, plays or podcasts.

I've added -b:a 320k -af "volume=3" to the default setting as in the wiki to change the default from VBR(Variable bit rate) to CBR(Constant bit rate) 320K and set the volume to 3x, this appears to be the maximum level before distortion or applying normalization.

Next to GIP, ffmpeg is one of my favourite tools.
