Software Usage Instructions

Add files: Click the "Select File" or "Select Folder" button, or directly drag and drop video files, audio files, or entire folders into the software window. Video formats such as MP4, MOV, AVI, and MKV are supported, as well as audio formats such as MP3, WAV, M4A, and FLAC.
Traverse subdirectories: When importing a folder, you can check "Traverse subdirectories" to process all media files in nested folders, and select "Keep original path structure" to maintain the original directory hierarchy for output files.
Select a voice-changing preset: Choose the desired effect from the 35 built-in voice-changing presets, for example:
- Character voices: Male to female, female to male, loli voice, uncle voice, child voice, monster voice, alien voice, etc.
- Scene sound effects: Telephone voice, walkie-talkie voice, radio host, news broadcast voice, livestream microphone voice, documentary narration voice, etc.
- Atmosphere effects: Echo cave, spatial reverb, horror atmosphere voice, ethereal fantasy voice, tunnel echo voice, etc.
- Anonymity protection: Slight anonymous voice change, strong anonymity protection voice, used to hide original voiceprint characteristics
Customize parameters: After selecting the "Custom" preset, you can adjust pitch shifting and reverb parameters yourself, and set the dry/wet ratio to control the strength of the voice-changing effect.
Configure output options:
- Output directory: Set the save location for processed files
- Audio output format: Keep the original format, or convert to MP3, WAV, M4A, FLAC, OGG, OPUS, etc.
- Video audio track encoding: For video files, you can choose audio track encoding methods such as AAC and MP3
- Concurrent threads: Adjust the number of files processed simultaneously according to device performance
Start processing: Click the "Start Processing" button, and the software will automatically complete batch voice changing and output. Processing progress and logs will be displayed in real time. After completion, go to the output directory to view the results.

FAQ

A: Video supports common formats such as MP4, MOV, AVI, MKV, FLV, WMV, WEBM, M4V, TS, MPG, and 3GP; audio supports formats such as MP3, WAV, M4A, AAC, FLAC, OGG, WMA, OPUS, AC3, and AIFF, covering most file types used in everyday processing.

A: No. The software only applies voice-changing processing to the audio track in the video. The image portion is preserved as-is and repackaged, so the image quality and duration will not change; only the sound will have the voice-changing effect.

A: Yes. After selecting the "Custom" preset, you can separately adjust pitch shifting (raising or lowering the pitch) and reverb intensity, and control how noticeable the voice change is through the dry/wet mix, making it easy to create your own voice effect as needed.

A: No. All voice-changing processing is completed on your local device. Video and audio files are not uploaded to any server, helping better protect your privacy and data security.

A: The software uses multi-threaded concurrent processing and supports bulk folder import and subdirectory traversal, making it suitable for large batches of files. You can adjust the number of concurrent threads based on your device configuration; computers with better performance can increase it appropriately to improve processing speed.

A: Yes. Audio files can be output in their original format or converted to formats such as MP3, WAV, M4A/AAC, FLAC, OGG, and OPUS, with selectable quality levels; for video files, the audio track can be encoded as AAC, MP3, and other formats.

A: No, the original files will not be overwritten. The processed results will be saved to the output directory you specify. If files with the same name are encountered, numbers can be added automatically to distinguish them. The original files will be kept intact for easy comparison and backup.
