Sep 19, 2018 With the ability to isolate vocals, percussion, bass and more - iZotope RX7 with Music Rebalance just gave you full control of your tracks. Now Available on Rent-to-Own. Audio waveform display in RX is very flexible. It has the choice of interpolation order and has the ability to show intersample peaks. When audio signal is converted from digital to analog, it undergoes the process of bandlimited reconstruction. This is a special kind of interpolation applied by a D/A converter.
Resample allows you to convert an audio file from one sampling rate to another. Sample Rate Conversion (SRC) is a necessary process when converting material from one sampling rate (such as studio-quality 96 kHz or 192 kHz) to another rate (such as 44.1 kHz for CD or 48 kHz for video).
Display cursor coordinates in status bar: When enabled, the time coordinate of the cursor is shown in the status bar at the bottom of the RX main window. The amplitude of the audio at the cursor position and the frequency at the cursor position is also shown.
Show analog waveform: When digital audio is played back, it is converted to analog. The peak values in the analog waveform can be larger than the peaks in the digital waveform, leading to clipping in the output of a digital-to-analog converter. When Show analog waveform is enabled, RX will compute an analog waveform in the background. Any peaks will be highlighted in red on top of the existing digital waveform.
Note
RX will automatically display an analog waveform when zooming in at extreme zoom levels.
Offload waveform calculations: When enabled, RX’s waveform display will be computed in the background. This allows very large files to be loaded very quickly, but it slows down RX’s waveform displays.
Waveform interpolation order: If you zoom into the waveform so that individual samples become visible, RX will display an upsampled analog waveform as well as the individual digital samples. The interpolation order controls the quality of upsampling. Higher values yield more accurate analog waveforms at the expense of CPU usage.
Brightness: Adjusts the general brightness of the RX interface, allowing you to make RX more readable on your specific display.
Floating window opacity: Changes the opacity for RX’s floating windows. This can be useful if you wish to leave floating windows on top of the spectrogram and waveform without completely obscuring the display.
Customizing Keyboard Shortcuts
While RX includes default keyboard shortcuts, you can also customize them to your liking.
Refer to the Keyboard Shortcut Guide to reference a list of default RX key commands and find the internal shortcut command names used by RX. Referring to the guide can help you quickly identify the name of the key commands you want to customize and search for them in the “Show commands containing” field (explained below.)
Using the Alt modifier on Windows
On Windows systems, by default, “Alt + a letter” will open the corresponding menu for your currently open application. Alt + V for example will open RX’s View menu drop down. By default, none of RX’s shortcuts should conflict with these keyboard shortcuts, however if you wish to assign Alt + V to another operation, it will take precedence over the View menu.
Disabling the selection undo/redo option
Provides options to authorize or de-authorize RX (explained in the Authorization chapter), launch the iZotope Updater and choose how often the Updater automatically checks for updates.
RX 6 Audio Editor supports the use of the following plug-in formats in the “Plug-in” module:
Disable: Disables the associated plug-in format. This will clear the scanned plug-in list for that format. Re-enabling that plug-in format will prompt RX to re-scan that plug-in format.
Note
VST plug-in folders: Allows you to add or remove custom VST2 plug-in folder paths. RX uses the system VST2 plug-in folder by default. If you are using a custom directory for VST2 plug-ins, use this option to ensure that those VST2 plug-ins will be scanned.
Note about sub-folders when scanning for plug-ins
Group plug-ins by name in plug-in menus: When enabled, the RX plug-in menu will group plug-ins by common first words, usually the manufacturer’s name. When disabled, the RX plug-in menu will appear as a single, alphabetically sorted list.
Rescan: If RX detects that a plug-in is unstable, it will blacklist it and prevent it from being opened. The rescan option allows you to clear the blacklist of unsupported plug-ins and rescan all installed plug-ins in case an RX update or an update from the plug-in manufacturer resolves the issue.
iZotope’s award-winning RX 6 Audio Editor is the industry standard for audio repair, restoration, and enhancement. It offers a comprehensive suite of tools focused on alleviating common to complex audio issues. Post production professionals, audio engineers, and video editors alike use RX to transform problematic recordings into production-ready audio.
The RX 6 Audio Editor is a visual, selection-based editing environment. Most of its user interface is devoted to the Spectrogram/Waveform display, an integral part of the RX editing workflow. The display enables you to refine and visualize your audio, allowing for better recognition and selection of problem areas.
