atracdenc - ATRAC Decoder Encoder

Implementation of ATRAC1, ATRAC3 encoders

Building:

You need:

• C++11 compiler.
• cmake >= 3.0
• libsndfiles

binary:

cd src
mkdir build
cd build
cmake ../
make

binary and tests:

cd test
cmake ../
make

Usage:

ATRAC1:

./atracdenc --encode -i ~/01.wav -o /tmp/01.aea

ATRAC3: - use it only if you want to improve it ;)

You can use --help option to get help

Limitations:

• Bit allocation based on the tonality of the signal (see http://www.minidisc.org/aes_atrac.html)
• Only 44100 16bit wav input file

Other problems:

• Unfortunately software using ffmpeg library often incorrectly detects AEA file. Be careful, the noise in case of wrong detection can be extremely high.
