Hi Daniel, read your post and was curious. Most of my mp3s were already ripped on my PC and were transferred via the B2 upload facility and later NAS. I decided to run a wee test.
I'm on software version B2 26th Jan 2021
I ripped a CD with the mp3 compression rate set to 265k.
Let it compress the files and then looked at them using NAS on my PC.
There were 10 tracks all had different bit rates, ie 120, 108, 115, 112, 116, 115, 120, 112, 124 and 124 kbs.
None were 128k or 256k spot on. Any ripped mp3s tracks I've done on my PC have a defined bit rate ie. 128k or 256k.
Any ideas folks.
