Audio Effects

We can only affect three things:

Amplitude

Time

Frequency

Each of the effects that we will look at can affect many or just one of these properties.

Many Digital Audio Effects run in realtime. Their are several differnt kinds of realtimes effects.

DirectX/VST- non destructive real time effects like TDM but runs on CPU

DirectX and TDM effect are restricted by the amount of processing power.

TDM's run on a single dedicated processor and DirectX effects run on the CPU.
