SenseAudio Video BGM Maker
Generate original, royalty-free background music matched to a video's mood and duration. Users describe their video in plain language — no music terminology required.
Step 1: Collect Input
Two paths:
A — Free description: User describes their video naturally.
"一个人在雨天咖啡馆看书的Vlog，时长45秒"
"开箱科技产品，要有未来感，30秒"
"宠物猫咪日常，轻松可爱，1分钟"
B — Preset scenes (quick pick): If the user wants to skip describing, offer these:
| # |
场景 |
默认风格 |
| 1 |
美食探店 |
warm acoustic, appetizing |
| 2 |
旅行Vlog |
cinematic, adventurous |
| 3 |
产品开箱 |
electronic, modern, clean |
| 4 |
运动健身 |
energetic, driving beat |
| 5 |
宠物日常 |

| 6 |

minimal, focused, corporate |
| 7 |
情感故事 |
piano ballad, emotional |
| 8 |
城市街拍 |
lo-fi, chill, urban |
Also ask: 视频时长？ (default: 30秒)
Step 2: Translate to Music Parameters
Map the description to style tags. Think in terms of: genre + mood + instrumentation + energy level.
| Scene / Keyword |

lo-fi, cafe, acoustic guitar, warm, relaxed |

| 情感 / 治愈 / 温暖 |

traditional Chinese, guqin, erhu, cinematic |
Always append duration hint to style: "30-second loop" or "60-second complete piece with build and resolution".
Duration strategy:
- ≤30s →
"short loop, complete in 30 seconds, no long intro"
- 30–90s →
"complete piece, build up in first third, peak in middle, resolve at end"
90s → "extended piece with intro, development, and outro"
Step 3: Generate 3 Versions
Always generate 3 variations with slightly different instrumentation — same mood, different texture. This gives the user real choice without requiring them to re-describe.
Build 3 style strings from the base style:
Version A: <base_style>, <primary instrument>
Version B: <base_style>, <alternative instrument>
Version C: <base_style>, <third instrument variation>
Example for "咖啡馆Vlog, 45秒":
- A:
"lo-fi, cafe, acoustic guitar, warm, relaxed, 45-second complete piece"
- B:
"lo-fi, cafe, piano, warm, relaxed, 45-second complete piece"
- C:
"lo-fi, cafe, jazz guitar, mellow, relaxed, 45-second complete piece"
Submit all 3 in parallel:
for i in 1 2 3; do
RESP=$(curl -s -X POST "https://api.senseaudio.cn/v1/song/music/create" \
-H "Authorization: Bearer $SENSEAUDIO_API_KEY" \
-H "Content-Type: application/json" \
-d "{
\"model\": \"sensesong\",
\"instrumental\": true,
\"style\": \"<STYLE_V${i}>\",
\"negative_tags\": \"vocals, lyrics, singing, spoken word\"
}")
TASK_IDS[$i]=$(echo $RESP | jq -r '.task_id')
echo "Version $i task: ${TASK_IDS[$i]}"
done
Poll all 3 tasks (check every 5s):
for i in 1 2 3; do
while true; do
POLL=$(curl -s "https://api.senseaudio.cn/v1/song/music/pending/${TASK_IDS[$i]}" \
-H "Authorization: Bearer $SENSEAUDIO_API_KEY")
STATUS=$(echo $POLL | jq -r '.status')
[ "$STATUS" = "SUCCESS" ] || [ "$STATUS" = "FAILED" ] && break
sleep 5
done
RESULTS[$i]=$POLL
done
Output
Present all 3 versions clearly:
