Although limiting will actually occur at much lower ratios. At much higher such as 50:1, then in real terms no change will occur, hence the term limiting, as the user is limiting the level to a predetermined amount, set by the threshold. For example a compression of 8:1 would mean that for every 8db of change past the threshold then only 1db will occur.

Ratio – This is the amount of compression once the signal passes the threshold.Threshold – This is the level which sets where compression should start to be applied.Broadly speaking, the harder a sound is compressed the more obvious it becomes. There is no right or wrong way, just a matter of taste. It can be applied as an effect, so that the sound is obviously compressed or in subtle ways so that compression is applied in as transparent way as possible. Compression, or dynamic range compression is used to reduce the dynamic range (the difference between the quietest and loudest parts) of the signal.
