Social media ads live or die on timing. The best ads sync music peaks to key moments — product reveals, logo drops, CTA screens. Trackyard’s hit point alignment automates this sync perfectly.

​
The Challenge

You’re cutting a 15-second Instagram ad:
  • Product appears at 8 seconds
  • Music should hit its peak exactly when the product enters the frame
  • Traditional libraries require manual audio editing to align the hit
Problem: Manual alignment takes 5-10 minutes per ad variant. At scale, this doesn’t work.

​
The Trackyard Solution

Use hit_point_seconds to choreograph the music’s climax to your reveal moment. 
curl -X POST https://api.trackyard.com/api/external/v1/download-track \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "track_id": "trk_abc123",
    "duration_seconds": 15,
    "hit_point_seconds": 8
  }' \
  --output ad_music.mp3
What happens:
  1. Trackyard finds the dominant energy peak in the track (the biggest drop/hit/crescendo)
  2. It selects a 15-second segment where that peak lands at exactly 8 seconds
  3. You get a clip perfectly timed to your product reveal
Zero manual editing.

​
Example: Product Reveal Ad

Scenario: 15-second Instagram Reel ad for a new sneaker Storyboard:
  • 0-7s: Product shots, building anticipation
  • 8s: Sneaker reveal ← music should peak here
  • 9-15s: CTA + logo
Request: 
{
  "track_id": "trk_xyz789",
  "duration_seconds": 15,
  "hit_point_seconds": 8
}
Result: Music builds for 7 seconds, hits the peak right as the sneaker appears, then resolves into the CTA.

​
Common Ad Formats

Typical structure:
  • 0-7s: Setup/problem
  • 8s: Product reveal
  • 9-14s: Benefits
  • 15s: CTA
Request:
{
  "duration_seconds": 15,
  "hit_point_seconds": 8
}

​
A/B Testing Ad Variants

Run the same ad with different music to test performance: 
# Search for different vibes
tracks = [
    search("upbeat electronic music"),
    search("warm acoustic music"),
    search("epic cinematic music"),
]

# Generate variants with the same timing
for i, track in enumerate(tracks):
    audio = download(
        track_id=track["id"],
        duration_seconds=15,
        hit_point_seconds=8  # Same reveal timing across variants
    )
    save(f"ad_variant_{i}.mp3", audio)
Test which vibe drives the highest CTR while keeping the visual edit identical.

​
Best Practices

Electronic drops, orchestral crescendos, and hip hop hits work best.Good candidates:
  • EDM with build-ups and drops
  • Cinematic music with crescendos
  • Hip hop with bass hits
Less ideal:
  • Ambient (no clear peaks)
  • Minimalist classical (subtle dynamics)
If the alignment feels slightly off, try adjusting ±1-2 seconds:
// Original
{"hit_point_seconds": 8}

// Try earlier
{"hit_point_seconds": 7}

// Try later
{"hit_point_seconds": 9}
Generate multiple music options upfront:
  1. Search for 5 different tracks
  2. Download each with the same hit_point_seconds
  3. Swap the audio track in your video editor
  4. Test all 5 variants simultaneously
Best hit point placements:
  • Product reveals
  • Logo drops
  • Before-and-after transitions
  • CTA screens
  • Brand moments

​
Code Example: Multi-Platform Ad

Same video, different durations for each platform: 
platforms = [
    {"name": "instagram", "duration": 15, "reveal_at": 8},
    {"name": "tiktok", "duration": 60, "reveal_at": 35},
    {"name": "youtube", "duration": 30, "reveal_at": 18},
]

# Search once
track_id = search("upbeat music for tech product")["tracks"][0]["id"]

# Generate platform-specific clips
for platform in platforms:
    audio = download(
        track_id=track_id,
        duration_seconds=platform["duration"],
        hit_point_seconds=platform["reveal_at"]
    )
    save(f"ad_{platform['name']}.mp3", audio)
