With an additional zoomed waveform display, seeing the music up and close is simple. But more than making working with music easy, the zoomed waveform is practical. When you can see the waveform zoomed up close, understanding the music in a visual way is easier, and setting music loop markers is much more accurate.
The zoomed waveform can be stretched horizontally and vertically as well, to give you a larger area to look at and make setting loop markers easier. They can be quite small (actual size):

Or they can be very large (25% actual size -- click to zoom to actual size or the width of your browser):

The waveform resolution can be set finer or coarser depending on your needs. Fine waveform resolutions are often nicer to look at, but consume more computer power and take longer to create and load. For most computers, the finest resolution available is best, but older computers should use lower resolutions.
