TWD: Tracing Wave Drawing is a tool used to copy using Bezier curves one audio wave based on a background image then export data to floating point or Wav Audio.
The bezier curves generated data "," floating that are stored in a text box are the coordinates of each segment consisting of the waveform, only in this way can be exported waveform copied and import it into another instrument hardware or software ..
You can also experiment with TWD since not only limited to the field of Audio...
