Hide/Show View Frame: The light blue View Frame, found in the Waveform Editor display is a navigating and editing tool which allows you to control the area of the zoomed view. The Hide/Show View Frame button toggles the View Frame on and off in the Editor display. If you're currently inside a zoomed view (looking inside the frame, as it were) this button is disabled. For more on the View Frame, read on. The Waveform Editor HyperEngine's Waveform Editor display is dominated by the waveform overview. The waveform overview is a graphic representation of your audio file, which is used for viewing, processing and editing audio files. Let's take a close look at the elements of the Waveform Editor display, then see how it acts when playing pieces of audio. Elements of the Waveform Editor When first opening a File Document, the Waveform Editor display shows the entire file (zoomed out all the way) as the initial default display. In this display you can navigate (zoom) through the file, from the lowest level of detail (seeing entire file) to the highest level of resolution (viewing each sample). Navigation is assisted by the View Frame, detailed in the following section. When you're zoomed into an audio file, the scroll bar at the bottom of the editor display becomes active, and allows you to quickly navigate through a zoomed view. For fastest, easiest navigation just use your Mac keyboard's arrow keys. At the far left hand side of the Waveform Editor display is a numeric scale, ranging from 0% to 100% indicating waveform amplitude as a percentage of total system headroom. The green band located between the amplitude scale and the beginning of the waveform overview is a marker indicating the beginning of file. The red band located at the far right hand end of the waveform overview is another marker indicating the end of file. The green and red bands are there for your visual reference, so you'll always know when you're at the top, or tail end, of a particular file. They also come into play as assistants to the selection and View Frame tools, as we'll examine later. Along the bottom edge of the Waveform Editor is a time display indicating file time in hours, minutes, seconds and milliseconds. Note the "tick mark" directly above the "hours" numerals, indicating the exact position of the particular time reading. Waveform Editor: Playing Sound Files When you play a sound file, a dotted yellow playback cursor scrolls across the waveform overview to show you the current file position. The playback cursor is not only a visual aid, it can be used to specify where you want playback to begin (assuming you've made no selection in the waveform overview). Click anywhere in the waveform overview to reset the playback cursor to a new position. Now click on the Play button (or press the space bar) to begin waveform playback from the playback cursor location. Click on the Stop button (or press the Return key) to end playback and return the playback cursor to the beginning of the file. Note that the Pause (spacebar) command affects the playback cursor differently than the Stop (Return) command. [. . . ] HyperEngine's dither algorithm can also be used for 24 or 16-bit sound file processing. Here's why: HyperEngine does all its effect processing using 32-bit floating point calculations. This has much greater resolution than 24 or 16-bit linear digital audio sound files provide. However, the output of the effect must be converted to a 24 or 16-bit sound file. [. . . ]
