Specification requirements for audio input
Simple Subtitling has strict technical specifications for the input audio, which are determined by the design of its underlying algorithms:
- formatting restrictions: Only mono, 16kHz sample rate, PCM_16 encoded WAV files are supported.
- processing logic: This is set up to ensure the accuracy of the speech recognition model and to reduce noise interference
- Conversion program: The project has built-in FFmpeg integration, which automatically converts unconventional formats to standard input.
It's worth noting that the development team advises users to ensure audio quality at the preprocessing stage; a clear audio source can significantly improve the accuracy of subtitle generation, especially important when multiple speakers need to be distinguished.
