Unable to play some downloaded .mp3/Aiff
 
Lately, some music files (.mp3/.AIFF) doesn't downloaded (?) as they should with LimeWire 4.18.3 Pro on iMac G4 OS X 10.4.11.
The download seems to go well into iTunes Music library but they doesn't appear in iTunes 7.7.1. (Limewire folder or/and main Library)
Double click on them in the iTunes Music Library to force to play, doesn't work.
QuickTime or RealPlayer are not able to open/play them.
Opening the file into Sound Studio 2.1 show an empty xxMb file. :confused:
... A new kind of Junk ?... Do I miss something ?
BTW, this is not happen to all downloaded music file...

Probably, here's some sizes to stay away from http://www.gnutellaforums.com/downlo...tml#post327233

To know whether the file is deliberately corrupt is not simple but requires some visual deliberation. Compare files of same bit rate & check the file sizes. If the file sizes for the same bit rate are quite different, then chances are they are corrupt. Once downloading they appear as 32 kbps bit rate & play high speed or something lol.

iTunes will not play mp3pro files, however chances are those were deliberately corrupt files, else viruses pretending to be mp3's or aiff.

Don't forget there's other alternate osx programs out there too: Alternate Audio Players & support plug-ins. I like Toolplayer even though it's very simple player, it has a very wide range of formats it can play. More than SoundPlayer at a guess, though I haven't used that program for a couple of years.

Another one is Audion though it is much more limited than Toolplayer in the formats it can play. It does have some decent encoding options, playlist options, record options, visualise options, streaming, etc.

Not forgetting VLC can actually play a wide range of audio formats also. :)

Rhank to you.

Make sure you have some back up players. I'd recommend Audion & ToolPlayer. The latter is just a very simple player but has an amazing wide range of audio formats it can play. Audion has not been developed for a few years, but is still a good player all the same. It can play mp3pro which iTunes cannot, likewise for Ogg Vorbis files. And it can open playlists & create its own. Alternate Audio Players & support plug-ins

Yes my guess is those files you downloaded are unfortunately corrupt in some way. Again, check file sizes. For AIFF, you know that 1 minute is around 10 MB in size, so if it shows as 4 minutes & is less than 35 MB then you know it's probably fake or corrupt.

Bit rates, yes here's that post http://www.gnutellaforums.com/222466-post13.html

Oh .. mp3's that do not show any information when you hover your cursor over top in the search results are most likely fake. AIFF unfortunately rarely have such information tags so it's not easy to know. If you know the length of the song before hand, then that may help for AIFF files. I guess one second of an AIFF file runs for around 160 - 170 KB. Hope you're good at maths. lol :) (size of AIFF may vary very slightly depending on OS & OS version, etc.)

Am glad to know anyway the trouble doesn't come from my App.
What's the satisfaction to those guys, if it does on purpose ?... (No need to answer)
