View Full Version : Crackling sound artifacts when playing mp3 files

Hi everyone, this is my first post here. Im getting frustrated by this hard to explain but unmissible crackling sound that seems to accompany the playback of mp3 songs. It is most noticable on quiet parts, where just a few notes are played. The notes come out clearly as they should, but at the same time, crackled up versions of the same notes seem to come in at a higher frequency. This probably isnt making sense, but someone might now what it is about. I have tried listening to the same file with the same earphones from my computer, and the crackling is not present. The other strange thing is that if i convert the file to wma or flac, the crackling goes away completely, but if i convert it to ogg, the crackling changes to a more constant fuzzy hiss, but more than just background noise.

Apologies for the badly worded problem, but if anyone knows if this is a fault with my particular player or just a fact of iaudio 7 life, then i would very much like to hear. Thanks everyone.

Oh and also, when in music browser mode, when exiting or opening artists / albums that leads to a list of files/folders longer than can fit on the screen, playback of whatever it is im listening to pauses for a split second. It is very annoying. But it doesnt occur using file browser mode, so thats what im using now.

Can you snip out a suitable small example and post it for people (eg me) to test? Certainly not noticed that problem but then I tend to avoid .mp3 and use .ogg. Could well be you have a marginally defective unit .. there is plenty that can go wrong, much of which is hard to test for if it is purely SQ related.

Thanks for the quick reply, i converted my library to wma, and put that across. Then i was getting fed up with wma files not being in the right order, so just by chance tried putting an original mp3 back on. The sound quality was excellent.. as it should be. Now i have put my originial mp3 library back on and the sound is perfect. So i don't know how, but somewhere along the way something has been sorted out. Maybe the files became corrupt or something? I really dont know, but its fixed now. Thanks.

I have also the second problem, that you told.
In the "File" Modus, this problem also doesn't appear on my player.
But in the "Music" Modus I have the same problem like you.

So, I am not alone ;D
