Best Practices

Audio Quality

• File Formats: MP3, WAV, FLAC, AAC supported
• Sample Rate: 44.1kHz or higher recommended
• Clear Audio: Clean audio produces better visualizations
• Volume Levels: Normalized audio prevents clipping in visuals

Visual Design

• Contrast: High contrast between visuals and background
• Color Harmony: Use complementary or analogous color schemes
• Responsiveness: Match visual intensity to audio dynamics
• Safe Zones: Leave margins for platform UI overlays

Format Guidelines

Platform	Aspect Ratio	Resolution	Notes
YouTube	16:9	1920x1080	Landscape, full HD
Instagram Post	1:1	1080x1080	Square format
Instagram Reels	9:16	1080x1920	Vertical, Stories compatible
TikTok	9:16	1080x1920	Vertical format
Spotify Canvas	9:16	720x1280	3-8 second loops
SoundCloud	16:9	1280x720	Waveform style popular

Prompt Tips for Audio Visualization

Include these details in your prompts:

1. Visualization Type: Waveform, spectrum, circular, particle, 3D, abstract
2. Color Scheme: Specific colors, gradients, or palette style
3. Background: Solid, gradient, animated, space, etc.
4. Effects: Glow, blur, reflection, particles, trails
5. Reactivity: What responds to bass, mids, highs, beats
6. Format: Aspect ratio and resolution
7. Style: EDM, minimal, psychedelic, corporate, etc.
8. Branding: Space for logos, text overlays

Example Prompt Structure

"Create a [visualization type] for [audio type/genre].
Use [color scheme] with [background style].
Add [effects] that react to [audio elements].
[Format and resolution]. [Style description]."

Mode Selection

"Do you want fast & cheap, or high quality?"

Mode	Best For	Speed	Quality
max	Final releases, music videos, premium content	Slower	Highest
eco	Drafts, previews, social media clips, podcasts	Faster	Good

  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Create a spectrum analyzer visualization for this EDM track",
    "audio_urls": ["https://example.com/track.mp3"],
    "session_id": "viz-project-001"
  }'

# Refine colors
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Change the color scheme to cyan and magenta, add more glow",
    "session_id": "viz-project-001"
  }'

# Add effects
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Add particle trails on the peaks and a subtle mirror reflection",
    "session_id": "viz-project-001"
  }'

Batch Generation for Multiple Tracks

# Track 1
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Create a circular visualizer for this track, purple and blue colors",
    "mode": "eco",
    "audio_urls": ["https://example.com/track1.mp3"]
  }'

# Track 2 (same style)
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Create a circular visualizer for this track, same purple and blue style as track1",
    "mode": "eco",
    "audio_urls": ["https://example.com/track2.mp3"]
  }'

Error Handling

Error	Cause	Solution
Failed to create prediction: HTTP 422	Insufficient balance	Top up at eachlabs.ai
Audio processing failed	Unsupported format or corrupted file	Use MP3/WAV, check file integrity
Timeout	Long audio or complex visualization	Set client timeout to minimum 10 minutes
Sync issues	Complex beat detection	Provide clear, well-mastered audio
