AAC to iPod: Convert AAC(Advanced Audio Coding) video to iPod with River Past Crazi Video
What is
AAC?
AAC, Advanced
Audio Coding, is a technique for compressing digital audio files. Officially
part of the MPEG-4 standard,
it is most widely used to create small digital audio files.
AAC is conceptually similar to the ubiquitous MP3 format. AAC is a lossy
algorithm, meaning the original digital audio cannot be recreated from the compressed
bits alone. In terms of audio fidelity, however, there is no loss of data if
the compressed audio is properly encoded. AAC claims an advantage over MP3 in
this regard: while MP3 requires a bit rate of approximately 256 kilobits per
second (kbps) to achieve transparency, AAC can achieve the same quality at 128
kbps. This allows AAC files to be roughly half the size of MP3 files of the
same quality, and one-tenth the size of CD digital data.
AAC provides several other advantages over MP3. It is capable of handling
much higher and lower frequencies of sound, provides up to 48 channels of audio,
and allows the creation of low-latency audio necessary for two-way communication.
There are two types of AAC files. The most common one is embedded in MPEG-4
container. Its file extension is usually m4a. The popular iTunes encode
AAC audio in this format. You only need to have Apple QuickTime
installed to decode these files.
A less common one is the plain AAC file, usually with .aac file extension.
To convert from this type, you need to have DC-Bass
Decoder installed.
