Wskazówki

• Generation time: Average ~60-90 seconds. Submit task, wait 45 seconds, then poll every 5 seconds.
• Callback mode: Recommend using callback mode to avoid frequent polling.
• Audio expiration: Result URLs are valid for 15 days. Download promptly.
• Content moderation: Lyrics and descriptions must comply with content safety guidelines.
• Version selection:
  • V4: Classic version, stable and reliable
  • V4_5 / V4_5ALL: Improved versions, better audio quality
  • V4_5PLUS: Enhanced version (recommended), balanced quality and speed
  • V5: Latest version, best audio quality and creativity
• Custom mode vs simple mode:
  • customMode: false: Simple mode, only provide short description (max 500 chars), system auto-generates lyrics and style
  • customMode: true: Custom mode, provide full lyrics (max 5000 chars), specify style and title
• Lyrics writing tips:
  • Use standard song structure (Verse, Chorus, Bridge, etc.)
  • Leave blank lines between sections
  • Use markers like [Verse 1], [Chorus], [Bridge] to clarify structure
  • Lyrics should have rhythm and rhyme
• Style description:
  • Use music terminology (e.g., “pop”, “rock”, “jazz”, “orchestral”)
  • Combine multiple styles (e.g., “orchestral, emotional, film score”)
  • Describe mood and atmosphere (e.g., “upbeat”, “melancholic”, “energetic”)
• Vocal selection:
  • vocalGender: "m": Male voice, for lower range, powerful songs
  • vocalGender: "f": Female voice, for higher range, emotional songs
  • Not specified: System chooses based on style
• Instrumental mode:
  • instrumental: true: Generate instrumental only (no vocals)
  • Ideal for background music, soundtracks, ambiance
  • Describe instruments and atmosphere in prompt, no lyrics needed
• Weight parameter tuning:
  • styleWeight (0-1): Style intensity, higher = strictly follows specified style
  • weirdnessConstraint (0-1): Creativity level, lower = conservative, higher = innovative
  • audioWeight (0-1): Audio quality weight
  • Recommended range: 0.4-0.7
• Negative tags: Use negativeTags to avoid unwanted elements (e.g., “noise, distortion, low quality”)
• Best practices:
  • Test with simple mode first to explore styles and effects
  • Once satisfied, use custom mode for full lyrics
  • V4_5PLUS or V5 versions offer best quality
  • Clear structure and strong rhythm in lyrics yield better results
• Output format: Each generation produces 2 tracks. Each track includes an audio_url (MP3) and image_url (cover art JPG). Parse resultJson and iterate over the resultUrls array of objects — do NOT assume it is a plain string array.
• Lyrics in response: When vocals are included, the lyrics field in the status response contains the full auto-generated (or echoed) lyrics with section markers like [Verse 1], [Chorus], etc.
