+&lt;p&gt;9 uses the slowest &amp; best possible version of all algorithms.
+&lt;p&gt;&lt;b&gt;7 is the recommended setting&lt;/b&gt; while 4 still produced reasonable quality at good speed.

+In this mode, the encoder makes no use of potential correlations between the two input channels; it can, however, negotiate the bit demand between both channel, i.e. give one channel more bits if the other contains silence or needs fewer bits because of a lower complexity.
+&lt;p&gt;&lt;b&gt;Joint-Stereo&lt;/b&gt;&lt;br&gt;
+In this mode, the encoder will make use of correlations between both channels. The signal will be matrixed into a sum ("mid"), computed by L+R, and difference ("side") signal, computed by L-R, and more bits are allocated to the mid channel. This will effectively increase the bandwidth if the signal does not have too much stereo separation, thus giving a significant gain in encoding quality.
+&lt;p&gt;&lt;b&gt;Mono&lt;/b&gt;&lt;br&gt;
+The input will be encoded as a mono signal. If it was a stereo signal, it will be downsampled to mono. The downmix is calculated as the sum of the left and right channel, attenuated by 6 dB.</string>
