VocalSync rendering options (Platinum only)

VocalSync uses a particular formula, or algorithm, to stretch the audio. It uses a processor-friendly algorithm for online previewing, and a more processor-intensive algorithm for offline render. For details, see To render a Region FX and VocalSync editor.

By default, VocalSync clips inherit the default online and offline render modes as defined in Aud.ini, and you can override the default render modes for selected VocalSync clips directly from the Clip Properties Inspector. This simplifies optimizing the rendering quality to match different types of voices.

Figure 77. Use the Clip Properties Inspector’s AudioSnap section to specify the selected VocalSync clip’s render modes.

To choose render algorithms for an individual VocalSync clip

1.	Select the VocalSync clip or clips you want to edit.

2.	Press SHIFT+I to open the Clip Properties Inspector. The Clip Properties Inspector displays settings for the currently selected clip(s).

3.	In the Clip Properties Inspector, click the AudioSnap section’s header bar.

The AudioSnap section displays the current online and offline render modes of the selected clip. If you select multiple clips that have different render modes, the Online Render and Offline Render lists display (Multi).

4.	Select the desired Online Render or Offline Render mode. The options are as follows:

Online Render. This choice determines what stretch algorithm is used during real-time playback. For more information about render modes, see Algorithms and rendering. The options are as follows:

Default. This mode uses the default Groove Clip algorithm (the same algorithm used for stretching Groove Clip files). For information about specifying the default online render mode, see To specify default render modes for new VocalSync clips.

Groove clip. This mode works best with sustained vocal sounds, is faster than Percussion render mode, and uses less processing power.

Percussion. This mode can work better than the Groove Clip render mode for percussive vocals.

Note: The Online render mode is for preview purposes only during playback. The final audio quality will be greatly improved after the Offline render mode is applied during mixdown/export.

Offline Render. This drop-down menu lets you choose the algorithm that is used when you export or freeze VocalSync audio. Although the default Radius Solo (Vocal) algorithm is ideal for most voices, it’s worth experimenting with different algorithms to find what works best with your voice. The options are as follows:

Default. This uses Radius Solo (Vocal). For information about specifying the default offline render mode, see To specify default render modes for new VocalSync clips

Radius Mix. Best for clips containing polyphonic, stereo data (although this type of source material isn’t commonly used with VocalSync).

Radius Mix Advanced. Similar to Radius Mix, but exposes a Smoothing slider that adjust how much detail to preserve.

Radius Solo. Better for clips containing monophonic, solo instruments.

Radius Solo (Bass). Better for clips containing solo bass instruments, but can also be a good choice for low voices.

Radius Solo (Vocal). Usually best for clips containing solo vocals in normal singing ranges.

Same as Online. Uses the same choice as the Online field.

To specify default render modes for new VocalSync clips

By default, VocalSync clips inherit the default online and offline render modes as defined in Aud.ini. To specify the default render modes:

1.	Go to Edit > Preferences > Audio - Configuration File.

2.	Under Configuration Settings, click Edit Config File.

The Aud.ini file opens in the default Windows text editor.

3.	In Aud.ini, add a new entry called DefaultVocalSyncOfflineStretchMethod or DefaultVocalSyncOnlineStretchMethod and set its value to 7. For example:

[Aud]

DefaultVocalSyncOfflineStretchMethod=7

Valid values are as follows:

1 = Groove Clip Stretching (this is the default online render mode)

2 = iZotope Radius Low Quality (faster - currently not used)

3 = iZotope Radius Normal Mix Quality

4 = iZotope Radius for Solo Material

5 = ReCycle-style

6 = iZotope Radius for Solo Material for bass

7 = iZotope Radius for Solo Material for vocals and higher-pitched material (this is the default offline render mode)

8 = Indicates that offline mode should match the online mode

9 = iZotope Radius Mix Advanced

10 = SOLA stretching (experimental)

Note: It is not recommended to set the online method to the expensive types since it may cause glitches.

4.	Save Aud.ini and close the Windows text editor.

5.	Click Reload Config Settings to reload the current audio configuration settings from Aud.ini.

Note: Changing the default render modes will only affect new VocalSync clips. Existing VocalSync clips will retain whatever the default modes were when the VocalSync clips were originally created. To apply new default render modes to existing VocalSync clips, first remove the Region FX, then create the VocalSync Region FX again, then render the clips. Alternatively, assign the desired render modes for selected VocalSync clips directly from the Clip Properties Inspector. For details, see To choose render algorithms for an individual VocalSync clip.
