Sample Rate
Select the quality of encoding.
The higher Sample Rate means highter quality but with a
larger file size. We recommend 44100Khz - CD-audio quality.
Bitrate
Select the quality of encoding. Determines the number of bits per second.
The higher bitrate means highter quality but with a
larger file size. We recommend 128 Kbps.

Mode
You can select Stereo or Dual channel mode.
Dual Channel Mode - In this mode, the encoder will make use of a correlation
between both channels in order to achieve higher compression.
This will enhance the quality of constant bitrate recordings, and
reduce the size of variable bitrate recordings.
We recommend Stereo mode for best quality.
Copyright
Mark the encoded file as being copyrighted.
Original
Check this option if encoded file is original, otherwise the encoded file as being a copy.
CRC
Turn on CRC error protection.
It will add a cyclic redundancy check (CRC) code in each frame,
allowing to detect transmission errors that could occur on the
MP3 stream. However, it takes 16 bits per frame that would otherwise
be used for encoding, and then will slightly reduce the sound quality.
Private
Mark the encoded file as private use only.
