iPods que cortan las canciones

Ah... más que interesante el último de los links de Sera, parece que cuando un archivo es VBR (Variable Bit Rate) muchos programas usan el primer bitrate para estimar el tiempo que dura la canción o el podcast y eso produce diferencias entre el tiempo real de la canción/podcast y el tiempo que el programa estimó. Seguramente este es el problema que presentan muchos iPod como el mio, que más que un problema del iPod es un problema de como está grabado el archivo (o con que software).

No obstante, parecen no haber reportes de problemas similares con otros modelos de iPod diferentes al nano.

Whats is VBR?
In a song there are points that require high quality and points that require low quality(ie silence) so insead of having the whole file at 160kbps (CBR - Constant Bit Rate) we can use VBR - Variable Bit rate, and have say 96Kbps at points not requiring high quality and 192Kbps when we need it, having a overall small but high quality mp3. However the problem is many mp3 programs estimate the time of a mp3 based on the first bitrate they find and the filesize. With VBR you can get fairly random times and as most songs start with silence you usually get the predicted song length as much more than it is. Also when you jump throught the file in VBR 50% throught the file is not 50% throught the song. A VRR Null frame is placed at the beggining of the file to tell the MP3 player information about the song length and indexing throught the song. Some poor encoders don't produce this NULL frame or do it incorrectly so this program calculates a correct Null frame and replaces it. It can also fix other problems with mp3s as it deletes all non-mp3 content(other than tags you state you want to keep). It can help when merging two VBR mp3s together with a merging tool and then needing a newly calculated bitrate.
