| | 1 | [http://en.wikipedia.org/wiki/High-Efficiency_Advanced_Audio_Coding HE-AAC audio] v2 (with SBR + PS) is the superb audio encoder used to encode high quality audio at really low bitrates (32 kbit/s). Quote from Wikipedia "''Data from this testing also indicated that some individuals confused 48 kbit/s encoded material with an uncompressed original.''" |

| | 3 | In order to quickly compile your [http://217.20.164.161/~tipok/ libaacplus] library, you can type the following commands in your shell: |
| | 4 | {{{ |
| | 5 | # apt-get install libfftw3-dev pkg-config autoconf automake libtool unzip |
| | 6 | # wget http://217.20.164.161/~tipok/aacplus/libaacplus-2.0.2.tar.gz |
| | 7 | # tar -xzf libaacplus-2.0.2.tar.gz |
| | 8 | # cd libaacplus-2.0.2 |
| | 9 | # ./autogen.sh --enable-shared --enable-static |
| | 10 | # make |
| | 11 | # make install |
| | 12 | # ldconfig |
| | 13 | }}} |
| | 14 | |
| | 15 | P.S. If you are using Ubuntu, you'll most probably have to use sudo for the last 2 commands, like: |
| | 16 | {{{ |
| | 17 | # sudo make install |
| | 18 | # sudo ldconfig |
| | 19 | }}} |
