A systematic solution to improve the quality of song conversion
When a loss of sound quality is encountered, it is recommended that improvements be implemented according to the following priorities:
- Basic optimization (mandatory)::
1. Reference audio using 44 kHz sample rate (can be converted through tools such as Audacity)
2. Increase in the number of diffusion steps to 50 (-diffusion-steps 50)
3. Enable f0-condition to maintain original pitch (check f0-condition option) - Advanced Optimization::
1. Selected seed-uvit-whisper-base model (200M parameters)
2. Add the -semi-tone-shift parameter to fine-tune tone matching.
3. Use of professional dry sound recording equipment for pure reference audio - remedial measure::
The conversion can be done with tools like Adobe Audition:
- Noise reduction process (FFT filter)
- Dynamic compression (4:1 ratio recommended)
- High frequency compensation (+3dB@8kHz)
Special note: Background noise can cause the model to learn interfering features, and it is recommended that the reference audio signal-to-noise ratio be at least 30dB.
