decoding speed iPod video ~153% But in some players, the decoding speed is not enough. (e.g., H180 52.4% (thanks amiconn), H300 55.09% (thanks n1s)) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25994 a1c6a512-1295-4272-9138-f99709370657

TTA Hardware Players Library
|
|
============================
|
|
|
|
Version 1.2, (c) 2004 Alexander Djourik. All rights reserved.
|
|
|
|
* Introduction
|
|
|
|
This library provides to decode a multichannel 8,16 and 24
|
|
bits TTA audio files. TTA is a lossless audio format. Being
|
|
"lossless" means that no data/quality is lost in the compression
|
|
- when uncompressed, the data will be identical to the original.
|
|
The compression ratios of TTA depend on the type of music file
|
|
being compressed, but the compression size will generally range
|
|
between 30% - 70% of the original.
|
|
|
|
TTA format supports both of ID3v1/v2 tags. Detailed format
|
|
description is available at http://www.true-audio.com.
|
|
|
|
The decoder process has a minimal system requirements and does
|
|
not required to create a big additional memory pools. As the
|
|
TTA algorithms has a same system requirements both for decoding
|
|
and for encoding processes - the TTA recorder can be easily
|
|
realized also.
