I'm using my N800 to play back DAB recordings (taken from a Pure Evoke 3 radio which records DAB broadcasts as MP2 files direct to SD card) when on the move.

It's great that the N800 is able to do this out of the box but I've noticed that it plays some recordings with an annoying ringing distortion. All the recordings play fine on the Evoke 3, of course. The issue seems to be related to the bitrate of the broadcast; BBC Radio 4 at 128kbps seems problematic, for example.

Anyone else noticed similar problems or would care to suggest a solution that doesn't involve booting up my PC?
