Core Scenario & User Needs

Many users collect approximately 20 voice audios (mainly speech content) from short video platforms daily, using them as materials for voice cloning. This workflow faces two key pain points:

1. Collected audios often contain background noise, ambient hum, or electrical interference, requiring noise removal to retain clean human voices.
2. Volume levels vary significantly across audios (some too loud, others too soft), needing consistent adjustment to a standard level.

Enhanced Denoise & Volume Normalization (with Steps)

1. Optimized Denoise Feature – Get Clean Voices in One Click

The upgraded denoise feature now targets 5 common noise types, ensuring cleaner vocals for voice cloning:

• Wind noise removal: Detects low-frequency rumble from wind hitting microphones, applying adaptive filtering to eliminate “whooshing” sounds without muffling speech.
• Microphone noise reduction: Identifies static, pops, or electrical hum from cheap mics, using AI to isolate and suppress consistent mic-specific noise.
• Echo cancellation: Analyzes room reflections (common in indoor recordings), reducing repetitive sound waves to make vocals sound closer and clearer.
• Traffic noise filtering: Targets high-frequency car horns, engine roars, or street chatter, preserving speech while minimizing background commotion.
• Hissing noise elimination: Tackles constant high-pitched “hiss” from audio equipment, using spectral analysis to smooth out unwanted frequencies.

Step-by-Step Operation:

• Open the software and click “Import Files” to add short video audio materials (batch import supported).
• Select the “Denoise” option in the function panel; the software will automatically analyze noise patterns in the audio.
• Click “Start Denoising” – the system intelligently removes noise while preserving key voice details.
• Preview the result after processing, then click “Save” to export the clean voice file.

2. Enhanced Volume Normalization – Batch Standardize Volume Levels

Step-by-Step Operation:

• Import audio files (can be processed consecutively after denoising).
• Click “Volume Normalization” and set the target standard volume (e.g., -6dB/-9dB).
• Select “Batch Processing” mode; the software will automatically analyze each audio’s volume characteristics.
• Click “Start Normalization” to unify all audios to the set volume level.
• Save processed files individually or in batches after completion.

With these upgraded features and simplified workflows, users can efficiently process daily short video voice materials, meeting the purity and volume consistency requirements for voice cloning while significantly reducing repetitive work time.
