I noticed that Symfonium displays bitrate of all 128 kbps CBR MP3 files as 125 kbps and 320 kbps CBR MP3 as 313 kbps. Though not a playback issue, I am curious to know why is it so as other players display them in standard bitrates.
If only there was mandatory log requested to be able to answer …
Same bitrates were displayed when tested with local media provider
That log is empty and does not show any media playing …
I need to see the actual data to see and the screenshots would have help, you know all the stuff mandatory for reporting an issue 
I’ve reuploaded logs taken in playing state
The bitrate is 128000 this is 125 Kb as displayed, I suppose other apps display 128 Kib but don’t know anything about Si and drop the i
Isn’t it just the other way round?
kilo → SI unit, based on the power of 10
kibi → IEC unit, based on the power of 2
128000 bit = 128 kb = 125 kib
For my AAC files, the display seems to be concurring to that (showing 128 kb/s). For mp3 files it is as @samee described.
So you decide to shame me in public 
You should have a 10 day ban
Yeah, I make up for that with my many good deeds, including this one
