    Hello.

    I have a bit of an MP3 anomaly I'd like to try and figure out.

    I used Replay Media Catcher to sniff out and download a RTMP stream MP3 to my hard drive.
    I downloaded the same file 2 times on one computer and tried 1 time on a totally different computer.

    All 3 times (including the time on the totally different computer) the MB size of the MP3 file on my HD was exactly the same each time (for example when you look at properties of the file or run the cursor over the file).

    I know the stream should be 70min:52 secs, but for some reason some programmes don't recognise the last 10 seconds of the MP3.

    For example :
    When playing in "Adobe Audition 1.5" or "RealPlayer 10" or "windows Media Player" in the play bars it says the file is 70min:42secs long and stops/finishes playing when it reaches the end which it says is 70min: 42 secs.

    However when played in "GoldWave 5.16" and "Audacity" or "iTunes" or "burned to CD" the play bars says the file is 70min :52secs and plays for that long (an additional 10 secs of crowd noise at the end).

    The file plays perfect on any player but I don't understand why (as I described above) do some players not recognise the last 10 seconds of the file ? (even though it is obviously there as other players recognise the last 10 secs of crowd noise in the play bar and play it).

    Thanks in advance for any help !, I'd really like to find out what's happening.

    Some players interpret the end as white noise and discard it some don't what is the big deal? It has nothing to do with the mp3 it has do with the player setting that maybe you can alter or maybe they are built in. The displayed time is in the index which is correct. There is NO anomaly, it is as it should be. My suggestion is it you like the white noise play it with the player that plays it otherwise don't or cut out the white noise with audacity.

    You must have plenty of time on your hands to waist that amount of time over white noise.

    Hi,

    The missing 10 seconds is loud crowd noise which fades out, it's not silence if that's what you are thinking ?, every bit of the missing 10 seconds you can hear audio (crowd) fading out until the very last second.

    I don't know what you mean by the displayed time being the index, it's all 1 track, so why do some players show 1h10min42 secs and others show 1h10min52secs when it's all 1 track ?

    *It matters because it's a rare recording of a great band streamed for free on the 21st anniversary of the show which people have waited 21 years to hear, so I'd like to get the original file, but don't know if I have a corrupt file or something ;-)

    It does not sound corrupt. You can check for corruption, check the top sticky in this forum. There is a link for audiotester. That will specifically verify the time index against the audio.

    I would just cut out white noise. What band, what event?
