The key to improving audio generation is cue word engineering and parameter combination:
- Scene Adaptation: Clarify duration/mood/instrumentation in cue (e.g. "30 seconds of tense violin BGM")
- Format Selection: MP3 for short videos (small size), WAV for professional editing (lossless sound quality)
- Mixed Tips: Combination "Ambient Sound + Main Theme" description (e.g. "Rain + Piano Concerto")
- post-processing: Adjust volume curves with audio software after generation
- API Advanced: Control the number of seconds with the duration parameter, and synchronize the audio and video with the video_id.
Tests have shown that cue words that include BPM or chord progression numbers can improve musical expertise by more than 20%.
