Supported File Formats

A number of different file formats can be opened and edited in the RX Audio Editor. The next three sections outline the supported file formats and channel count configurations that can be opened in the RX Audio Editor. For information about file formats when saving or exporting files in RX, see the Saving Files and Exporting Files sections below.

Supported Audio File Formats

The following audio file formats can be opened in the RX Audio Editor: AAC, AAX (Audible Audiobook Format), AIFF/AIF, BWF, CAF, FLAC, M4A, MP3, OGG, SD2, WAV, WMA

Supported Video File Formats

The RX Audio Editor supports loading video file formats, but does not support video playback. When a video file is opened in RX, only the audio data from that file will be imported.

The following video file formats can be opened in the RX Audio Editor: AVI, M4V, MOV (RX requires that Quicktime is installed in order to open Quicktime file formats, e.g. .mov files.), MPEG, MPV, WMV

File Format Dependencies

Some file formats may have dependencies based on your operating system that may prevent you from importing them into the RX Audio Editor. For example, Windows native formats (like WMA and WMV) may not open on Mac and QuickTime formats (like AAC, MOV, and M4V) may require installing QuickTime on Windows and running the RX Audio Editor in 32-bit mode.

Supported Channel Configurations

The RX 7 Elements Audio Editor and RX 7 Standard Audio Editor support opening mono and stereo audio files.

Tip: Option for opening Split Stereo files in one tab

Mono audio files with (.L and .R) or (.1 and .2) extensions can be opened as either mono files (2 mono tabs) or split stereo (1 stereo file tab). See Preferences > Misc for more information. Note that this option is only applicable to split stereo files and does not apply to split surround files.

Multichannel File Support

The RX 7 Advanced Audio Editor supports opening audio files with up 10 channels per file tab. Multichannel audio device settings can be configured in the “Audio” tab of the Preferences menu.

The channel selector labels can be configured by selecting an option in the Channel Order menu. To access the Channel Order menu, right-click on the Time ruler and navigate to the “Channel Order” sub-menu. The options available in the Channel Order menu depend on the number of channels in the active file tab.

Creating New Files

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

If you have existing audio data in your clipboard (for example, if you have copied a selection from an existing file in RX), you can create a new file based on that audio data.

  • 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.

Managing File Tabs

RX supports having up to 16 files open at once. You can navigate between tabs by clicking on a tab or using the following keyboard shortcuts:

  • Select tab to the right of current tab: Control+Tab (Mac) or Alt+Tab (Windows)

  • Select tab to the left of current tab: Control+Shift+Tab (Mac) or Alt+Shift+Tab (Windows)

  • If you have multiple files open, an arrow button will appear to the right of the last visible tab. You can access file tabs that are not currently visible by clicking on the arrow button and selecting a tab from the menu.

Saving Files

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

NameDescriptionDefault Mac ShortcutDefault Windows Shortcut
SaveFor uncompressed file formats (.wav or .aiff): Overwrites the original file on diskCommand+SCtrl+S
For compressed file formats: Opens the Export File dialogCommand+SCtrl+S
Save As…For uncompressed file formats (.wav or .aiff): Save a copy of your file using the same file formatCommand+Shift+SCtrl+Shift+S

Autosave

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 Format Options

The following file formats are available when exporting files from the RX 7 Audio Editor:

  1. WAV - Uncompressed
  2. AIFF - Uncompressed
  3. FLAC - Compressed: Lossless Compression
  4. OGG - Compressed: Lossy Compression
  5. MP3[STD & ADV] - Compressed: Lossy Compression

Uncompressed File Formats

The RX 7 Audio Editor allows you to export files to the following uncompressed file formats: WAV and AIFF.

WAV

The following options are available when exporting files to this file format:

  • Bit Depth: Determines the bit depth of the exported file.
    • Choices include: 16 bit, 24 bit, 32 bit (float), 32 bit (int).
  • Dither: Determines the Dither Type to be applied to the exported file.
    • Choices include: None, White Noise (TPDF), Noise shaping (MBIT+)
  • BWF: When selected, the file will be exported with extended information that is included in the file header of a Broadcast Wave File.
  • Preserve Non-Audio Data: When selected, the exported file will retain the metadata of the original file.

AIFF

The following options are available when exporting files to this file format:

  • Bit Depth: Determines the bit depth of the exported file.
    • Choices include: 16 bit, 24 bit, 32 bit (float), and 32 bit (int).
  • Dither: Determines the Dither Type to be applied to the exported file.
    • Choices include:** None, White Noise (TPDF),** and Noise shaping (MBIT+).
  • Preserve Non-Audio Data: When selected, the exported file will retain the metadata of the original file.

Compressed File Formats

The RX 7 Audio Editor allows you to export files to the following compressed file formats: FLAC (Lossless Compression), OGG Vorbis (Lossy Compression) and MP3 (Lossy Compression).

FLAC (Lossless)

The FLAC file format offers lossless compression. The following options are available when exporting files to this file format:

  • Bit Depth: Determines the bit depth of the exported file.
    • Choices include: 8 bit, 16 bit, and 24 bit
  • Dither: Determines the Dither Type that will be applied to the exported file.
    • Choices include: None, White Noise (TPDF), and Noise shaping (MBIT+)
  • Compression Level: Adjusts the compression strength of the FLAC encoder. Stronger compression requires more CPU time during file encoding but results in a slightly smaller file. FLAC compression setting does not result in any quality change to the signal since FLAC is a lossless format.

OGG (Lossy)

The Ogg Vorbis file format offers lossy compression. The following options are available when exporting files to this file format:

  • Quality: AAdjusts the bitrate of the Ogg Vorbis compression algorithm. Higher bitrate values result in higher audio quality, but also increase the file size
  • Prevent Clipping: See the Prevent Clipping section below for more information.

MP3 (Lossy)

Download crossover 13 for mac. The mp3 file format offers lossy compression. The following options are available when exporting files to this file format:

  • Bit rate: Adjusts the bit rate of the MP3 compression algorithm. Higher bit rates result in higher quality audio but will increase the file size.
  • Bit rate control: Determines how (or if) bit rate varies over time.
    • Choices include: Constant bit rate (CBR), Average bit rate (ABR), and Variable bit rate (VBR).
  • Prevent Clipping: See the Prevent Clipping section below for more information.

Prevent Clipping

Predicts and prevents codec clipping when exporting audio in lossy formats (MP3 and OGG) by checking for decoded levels and adjusting levels of the original signal.

Prevent Clipping Processing Time

  • Prevent Clipping may run significantly slower than regular encoding, since it computes the correct level adjustment depending on the amount of clipping occurring in the file.
  • Files with little to no codec clipping usually will encode quickly, whereas heavily clipping files may take longer.

There are two types of file level adjustments that can be applied:

  1. Normalize: attenuates overall level of the file to ensure that the encoded/decoded file does not exceed 0 dBTP.
  2. Limiter: attenuates parts of the file that could become clipped to retain the level of non-clipping sections, while overall true peak levels are limited to 0 dBTP.

Choosing Normalize or Limiter

  • The Limiter will leave larger sections of the file unchanged in level and will only attenuate sections that would experience clipping. However, like any dynamic processing, this may create pumping.
  • The Normalize mode can completely avoid pumping at the expense of slightly reducing the overall level of the 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.
