Not just translating text,
but restoring the soul of your documents
High-frequency detail retention
AAC preserves more high-frequency detail than MP3, which enables AI to better distinguish sibilant sounds (such as s, sh, and f), thereby improving spelling accuracy.
Zero timeline drift
Optimized for video accompaniment, ensuring generated subtitle timelines are precisely aligned with the original video frames and eliminating audio-video desynchronization.
Multi-channel support
Automatically processes AAC files in 5.1 or 7.1 channels, intelligently extracting the center channel (dialogue) for recognition.
Privacy & Security
Your audio is used exclusively for machine translation, never for manual transcription, and is destroyed immediately after processing to ensure the security of your content.
Why does format matter?
- Precise formatting is the hallmark of professionalism.
- Reduce secondary formatting time.
- Ensure accurate and precise information delivery.
