To create a new file in RX:
1. Open the File menu
2. Select “New…”
3. You will be prompted for the name, sample rate and channel count of the new file you are creating.

Tip: Create a new file from the contents of the clipboard

• Open the “File” menu, choose “New from Clipboard” or use the keyboard shortcut: Command+Shift+N (Mac) or Ctrl+Shift+N (Windows)
  The new file will match the sample rate and channel count of the audio data present on your clipboard.

There are four ways to import a file into the RX 6 Audio Editor:

1. From the File menu, select Open… and select the files you want to open.
   
2. Drag and drop a file from your operating system into the RX UI.
   
3. Drag a file from Finder/Explorer to the RX icon in the Dock/Desktop.
   
4. Double-click on the RX logo in the middle of the RX Audio Editor interface when no files are loaded in the application

Saving Files

There are a number of ways to save a file in RX 6 Audio Editor. The Save Operations include:

Autosave

My second question was if you knew how to get rid of the ever present “hiss” sound in a garage band recording? The first one I was wondering how to adjust the microphone levels so when I belt into my microphone it doesn’t “blast out” or exceed the maximum recording volume limit. I have a Yeti microphone and I’ve tried everything (even standing away from it) and still I get these recordings where the sound is all muffled from my singing being too loud, so I guess does that have to do with garage band, or with the microphone?

The RX Audio Editor will automatically save backups of your editing session by default. When the RX application is launched, it will open your most recent editing session. The option to turn it off is located under the Preferences > Misc tab as “Resume last editing session when app starts.”

Saving RX Documents

You can save a file using the RX Document file format (.rxdoc) to archive your edits. An RX Document includes your original file, all the edits you’ve made to it, and your most recent selection and view state. RX Documents can only be opened in the RX Audio Editor. If you need to save your file so it can be opened somewhere else (like a DAW or media player), you need to export it in another format (like WAV or AIFF).

To save an RX Document, select File > Save RX Document… and select where you would like to store the file.

Keep in mind that the size of the RX Document file can be very large, especially if your list of edits include multiple processes on the whole file.

Export Options

When exporting, you will be able to define the output file name, directory, and bit depth. There are four ways you can export a file in RX 6 Audio Editor:

1. Export File

Export Selection

This option will allow you to export only the audio that is contained within your current selection, as opposed to the entire audio file.

1. Select File > Export Selection, and the Export File dialogue box appears.
   
2. Follow the additional aforementioned steps.
   

Export Regions to Files

This option allows you to export multiple regions of any audio file that has regions as discrete audio files. To export regions:

1. Select File > Export Regions to Files.
   
2. Choose the exported file format in the Export window
   
3. In the File Save dialogue box, navigate to where you want to save the files.
   
4. If you want, enter a prefix for your series of files in the Optional prefix field.
   

   Note

   • If you choose not to add a prefix, the names of the files will be the names of the regions. If any regions have the same name, numbers will be appended sequentially.
     
   
   
5. Click Save.
   

Export Screenshot

This option allows you to export your current Spectrogram/Waveform display as a PNG image file. This can be very helpful for archiving any restoration process or for forensic documentation.

When clicking on Export Screenshot from the File menu, your current Spectrogram/Waveform view will be used for adjusting your screenshot size and position.

Note

The Spectrogram/Waveform transparency balance must be set before selecting File > Export Screenshot as this cannot be changed in this window.

To define the size of your screenshot, simply click and drag in order to enlarge or shrink the screenshot window. The dimensions of your resulting screenshot will update automatically, however these can also be entered manually by clicking once in either Width or Height.

Note

The max resolution attainable for your screenshot will be limited by the individual computer’s screen resolution.

When you are finished changing the dimensions of your screenshot, click on the Save button to name and save your .PNG screenshot to your chosen directory.

Tip

To save screenshots faster (at the expense of having a larger file on disk), disable Maximum image compression.

Export History as XML

Export the Undo history list of your current file tab to an xml document

File Info

The File Info window can be opened by clicking Window > File Info and has two sections; General Info and More Info. The More Info section lists information dependent on the file type. The following table describes the information in each section including a list of possible entries in the More Info section:

Closing files

There are two ways to close a file:

1. Close: if you close a file that has uncommitted changes (represented by a dot or asterisk next to the file name in the tab display), RX will ask you if you want to save the file. RX does not ask about saving files when the application is closed because your changes are retained in its session data.
   
2. Close All: if you have any uncommitted changes in open files, RX will prompt you to save for every unsaved file.
   

The default keyboard shortcuts for closing files are:
