Our Audio Processing Tools
Starting as a single-purpose vocal removal tool, our solutions have expanded into a full suite catering to casual and professional audio needs. Today, we offer three core tools for voice cleanup, vocal separation, and creative voice work:
石引声音分离
This tool specializes in separating vocals from instrumentals, allowing users to remove vocals to create instrumental tracks or isolate vocal stems. It can also separate individual elements like drums, bass, guitar, piano, and supports additional stems including acoustic guitar, electric guitar, synthesizer, strings, and wind instruments.
分轨岛
Designed for audio refinement, this tool eliminates background noise and unwanted sounds from audio or video files, delivering cleaner voice and vocal output suitable for editing, publishing, or transcription.
语音AI 分声
Perfect for creative projects like podcasts or videos, this voice modification tool lets users adjust their accent and tonality to create unique voice experiences.
Additional tools in our suite include:
- Lead/Back Splitter: Extract lead vocals, backing vocals, instrumental mixes, and combined backing+music tracks.
- Voice Cloner: Clone voices to create professional ad reads and voiceovers quickly.
- Echo & Reverb Remover: Reduce echo and reverb to improve voice clarity in recorded audio.

How are processing minutes deducted?
Minutes are calculated by file length multiplied by the number of stem separation types selected (one type = two stems per file). Example: 5-minute file with 3 separation types =15 minutes deducted.
What are Fast and Relaxed modes?
