iTunes 9.1 converts AAC at 128kbps

Apple has implemented the conversion of music with high bit rate to 128kbps AAC.

One thing is fact. There are songs with high quality and other low. I believe many have already downloaded some of the net that had a small size and when he went to see, or rather hear, the quality was less than expected.

This bit rate is related to that. X has a song, for example, 4MB size and bit rate of 228kbps. When you hear it, the sound will come out clean, perfect. Since y has 1MB and rate of 99kbps. You know what I'm saying right?

See the differences below:

• 32 kbps - AM Quality, super low.
• 96 kbps - FM quality, low.
• 128-160 kbps - Quality Standard, average, good.
• 192 kbps - high quality, great.
• 224-320 kbps - Quality approximate the CD, super high, perfect riding technique, excellent.

A song with 228kbps provides more information in just one second. While the 99kbps 2s need to pass at least the same information. This causes the track has a large size.

This is commented that AAC is a standard chosen by Apple that claims to be the successor to MP3. He gives us a good conversion and quality with an average bit rate and therefore the file size.

If you have about 1GB of music and all are mixed in various sizes and formats, probably your iPod touch or iPhone, your processor and uses more battery to play them. Each time it is read, is a different size, different rate and so on. Would not it be better to leave more organized?

Converting all, the iPhone OS easier to locate and reproduce, without much effort.
