Bitrate of CBR MP3 files

Issue description:

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.



Additional information:

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 :wink:

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 :wink:

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 :stuck_out_tongue: You should have a 10 day ban :wink:

Yeah, I make up for that with my many good deeds, including this one :stuck_out_tongue_winking_eye:
