SenseAudio Lyric Flip

Rewrite a song with a new theme while keeping the original's structure. The key insight: AI-generated lyrics drift without constraints. By extracting a structural skeleton first and using it as a hard constraint, the output stays tight and singable.

Step 1: Collect Inputs

Ask the user for:

1. 参考歌词 — paste the original lyrics (or a verse/chorus excerpt)
2. 新主题 — what the new song should be about (e.g., "程序员加班", "失恋的猫", "创业失败")
3. 风格保留还是改变？ — keep the original vibe, or shift it (e.g., "结构照搬但从抒情改成摇滚")

Step 2: Extract the Skeleton (LLM task)

Analyze the reference lyrics yourself — no API call needed for this step. Extract:

Structure map:

• Segment labels: verse / chorus / bridge / pre-chorus / outro
• Number of lines per segment
• Character count range per line (e.g., 7–9 chars)

Rhyme scheme:

• Label each line's end sound: A, B, C...
• Example: AABB means lines 1&2 rhyme, lines 3&4 rhyme
• Note which segments rhyme internally vs. across segments

Rhythm feel:

• Syllable density: sparse (≤6 chars/line) / medium (7–10) / dense (11+)
• Repetition patterns: does the chorus repeat a phrase? Does a hook line recur?
• Emotional arc: builds up / stays level / drops at bridge

Example skeleton output to show the user:

段落结构：
  [verse] × 2 (各4行，7-9字/行，ABAB韵)
  [chorus] × 2 (各4行，6-8字/行，AABB韵，第4行重复)
  [bridge] × 1 (2行，自由韵)

情绪走向：verse 平静叙述 → chorus 情绪爆发 → bridge 转折收尾

韵脚示例（verse）：
  行1: __韵A
  行2: __韵B
  行3: __韵A
  行4: __韵B

Show this to the user and confirm before proceeding.

Step 3: Generate New Lyrics via API

Build a tightly constrained prompt using the extracted skeleton:

请根据以下结构约束，为主题"<新主题>"创作歌词：

段落结构：<从骨架提取的结构>
每行字数：<范围>
韵脚模式：<AABB/ABAB等>
情绪走向：<从骨架提取>
风格：<保留原风格 或 用户指定的新风格>

硬性要求：
- 严格遵守每段行数
- 每行字数在指定范围内
- 韵脚必须对齐（同一韵组的行必须押韵）
- 不要超出段落结构，不要添加额外段落

LYRICS_RESP=$(curl -s -X POST "https://api.senseaudio.cn/v1/song/lyrics/create" \
  -H "Authorization: Bearer $SENSEAUDIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"prompt\": \"<PROMPT>\", \"provider\": \"sensesong\"}")

TASK_ID=$(echo $LYRICS_RESP | jq -r '.task_id // empty')

Poll if async:

while true; do
  POLL=$(curl -s "https://api.senseaudio.cn/v1/song/lyrics/pending/$TASK_ID" \
    -H "Authorization: Bearer $SENSEAUDIO_API_KEY")
  STATUS=$(echo $POLL | jq -r '.status')
  [ "$STATUS" = "SUCCESS" ] || [ "$STATUS" = "FAILED" ] && break
  sleep 3
done
LYRICS=$(echo $POLL | jq -r '.response.data[0].text')

Step 4: Rhyme Check

After getting the lyrics, verify rhyme alignment yourself before showing the user. For each rhyme group in the skeleton:

• Extract the last 1–2 characters of each line in the group
• Check if they share a vowel sound (approximate check is fine)
• Flag lines that clearly don't rhyme with their group

Show the user a marked-up version:

[verse]
行1: 深夜还在敲代码 ✓ (韵A: -ā)
行2: 需求改了又改了 ✓ (韵B: -le)
行3: 眼睛快要睁不开 ✓ (韵A: -āi ≈ ā)
行4: 产品说明天上线了 ⚠ (韵B: -le ✓ 但字数偏长)

If rhyme issues are minor, note them and ask if the user wants to regenerate those lines. If structure is badly off, regenerate the full lyrics with a stricter prompt.

Step 5: Compose the Song

Once lyrics are approved, infer the style from the reference song and user preferences:

Reference vibe	Suggested style
流行抒情	pop ballad, piano, emotional
摇滚	rock, electric guitar, energetic
民谣	folk, acoustic guitar, storytelling
电子舞曲	electronic, synth, upbeat
古风	traditional Chinese, guqin, cinematic

If the user wants to shift the style, use their specified direction instead.

SONG_RESP=$(curl -s -X POST "https://api.senseaudio.cn/v1/song/music/create" \
  -H "Authorization: Bearer $SENSEAUDIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{
    \"model\": \"sensesong\",
    \"lyrics\": \"<APPROVED_LYRICS>\",
    \"title\": \"<新主题 + 仿 原曲名>\",
    \"vocal_gender\": \"<f|m>\",
    \"style\": \"<INFERRED_STYLE>\"
  }")

SONG_TASK=$(echo $SONG_RESP | jq -r '.task_id')

Poll until done (30–120s):

while true; do
  POLL=$(curl -s "https://api.senseaudio.cn/v1/song/music/pending/$SONG_TASK" \
    -H "Authorization: Bearer $SENSEAUDIO_API_KEY")
  STATUS=$(echo $POLL | jq -r '.status')
  [ "$STATUS" = "SUCCESS" ] || [ "$STATUS" = "FAILED" ] && break
  echo "作曲中..."
  sleep 5
done

Output

改编完成：

原曲结构：<骨架摘要>
新主题：<用户输入>
风格：<使用的曲风>

歌词预览：
<最终歌词>

音频：<audio_url>
封面：<cover_url>
时长：<duration> 秒

If the user wants to iterate — adjust rhymes, change a line, shift the style — update the lyrics and re-submit to the music API. The skeleton stays fixed; only the words change.
