Title: Itunes shows lower bitrates on songs until they are clicked
Post by: Mix3dmessagez on 2011-10-19 18:47:42
I encode using quicktime tvbr by converting to alac then encoding using quicktime.I have allot of songs, and found on my ipods song list when i'd click songs the bitrate would increase about 3-4 rates up on its average.Now, on itunes the songs do the same thing, only increasing when clicked on.Does this have any effect on the audio quality or anything, or is this just some kind of tag error.

iTunes probably doesn't bother to check the actual bitrate until you click on the track.

Where are you seeing the bitrate in iTunes?

IME, iTunes is very good at displaying accurate bitrates for properly-encoded files (i.e. files with complete, intact headers) in the "Bit Rate" column, under both OS X and Windows - I've never seen it change a bitrate value before.  What program are you using to encode from ALAC to AAC?

Also, where are you seeing a bitrate value on your iPod?  I've never seen an iPod display a bitrate, nor my iPhone 4 (nor do I care  ).

I've seen iTunes (for Windows) change the displayed* bitrate on files after having it edit tags, so I don't believe this is at all unusual.

(*) right-click on the columns header, select Bit Rate.

I use dbpower amp convert for alac, and quicktime aac program itself to convert.And when i said ipod i meant the ipod music tab in itunes does the same thing, i click a song, the bitrates updates *to what i assume is its actual value*, by like 3 points, for example, i click a song, it shows 99, when clicked, it shows like 102 or 103
