Converting files
After saving a file you may find that you need to change its attributes,
particularly if you are planning on mixing it with other files that have
different properties. When you convert a file, you can choose to convert
down, reducing quality and file size, or convert up. Converting up, such
as adding an extra channel or increasing the sample size, does not result in
an improvement in the sound of the file. This is because the attributes of
an audio file are determined at the time of its creation.
To convert a file, click Edit: Convert To. In the dialog box that opens,
you can choose to change the sampling rate, channels and sample size
according to your needs. (For more on these see the section on "Creating
a new edit window", page 346.) Once you click OK, the dialog box closes
and the waveform is changed accordingly.
Viewing waveforms
When you edit a waveform you may want to see part of it in greater detail
or display it in a more compressed format. You can do this in three ways:
click View: Zoom In and Zoom Out, by dragging the Zoom slider, or by
dragging on the borders of the Global View panel. (The amount you can
zoom depends on the size of the edit window, the length of the waveform
and the amount of the waveform shown in the window.)
Note: In Audio Editor it is possible to zoom down to the sample level. Editing at this
level however is often impractical as any changes you make may be inaudible
because of the sheer number of samples possible. For example, the smallest audio
file still has 11,025 samples per second.
