What is voice changer?
This feature allows you to transform the voice in a vocal track into another voice or even into the sound of instruments. The voice changer not only alters the timbre but also adjusts certain stylistic elements, while keeping the melody and lyrics unchanged.
How to change the voice?
Select your source audio
- What can be converted:
- Monophonic singing vocals or instrumental sounds without reverb or delay effects.
- Method A:
- Create a selection in the arrangement view that covers the content you want to convert. The selection can contain clips from both audio tracks and AI singer tracks. Therefore, you can convert any audio imported into ACE Studio or recorded directly within it, as well as AI-generated vocals created in ACE Studio.
- Once the selection is made, the source box will sync the selection and reflects the corresponding start and end positions.
- To clear the selection, click the ‘Clear’ button in the source box.
- Method B:
- Drag and drop an audio file into the source box.
- After importing, the audio waveform will be displayed in the source box.
- To remove the audio file, click the ‘Clear’ button in the source box.
- Once an audio file is loaded, the source box will no longer sync with any new selection changes.
Choose models
After selecting your source audio, you can choose models from the model list to perform the conversion.
The model list is divided into 3 tabs:
- Voices: Contains all pre-made singing voice changer models that transform the source into the target singing voice.
- Instruments: Contains all pre-made instrument voice changer models that transform the source into target instrument sounds.
- My Models: Contains all your customized voice changer models.
To select a model as the target, click on it. You can select multiple models to convert in one batch. To deselect a model, click it again.
Click on the picture of a model to preview its sound.
Once a model is selected, you can click the settings button to adjust the following parameters:
- Semitones: Adjust the pitch shift of the source by semitone.
Convert
After selecting your source content and target models, click the ‘Convert’ button to begin the conversion process.
- If you have selected multiple target models, the conversion will process them one by one as a batch.
- While the conversion is in progress, you can start a new conversion by selecting different content and target models.
Below the ‘Convert’ button, there are two checkboxes you can select:
- [Remove Instrumental]: Check this box to remove the instrumental part of the source content before conversion.
- [Remove Reverb and Harmonies]: Check this box to remove reverb and harmonies from the source content before conversion.
If you want to convert to instrument sounds, please note that regular singing vocals as the input source may not produce ideal instrument sounds due to the significant differences in their expressive forms. It is recommended to use vocal audio that mimics instrument sounds for better conversion results.
Use and manage the results
After the conversion is completed, the results will appear in the converted audio list. All converted audio files are organized by conversion batch.
- Drag and drop the title of a result audio to use it in the arrangement view. (You can also drag and drop the clip directly to your DAW)
- Click on the ‘folder’ icon to open the file location in your system.
- Click the ‘copy’ icon to copy the audio to your clipboard.
- Right-click on the title bar to delete this file from the right-click menu.
The converted audio files will be save under the project’s “Samples” folder. If working on a new unsaved project, you will lose all the files when you choose “Don’t save” when closing the program.
