Export & Rendering
Export and optimize audio with platform-specific settings, format conversion, loudness normalization, and batch rendering
Coming Soon
Export & Rendering features are currently under development and will be available soon. This documentation provides a preview of the capabilities that will be included.
Overview
Export & Rendering in Wubble Studio provides professional-grade output with platform-specific optimization, automatic loudness normalization, format conversion, and batch processing. Deliver audio that meets technical specifications for Spotify, Apple Podcasts, YouTube, broadcast, film, games, and more—all with a single click or API call.
Whether you need high-quality masters for streaming services, compressed files for web delivery, or professional stems for collaboration, Wubble Studio handles format conversion, sample rate conversion, bit depth adjustment, and loudness optimization automatically while maintaining the highest quality.
What You Can Export
Export Formats
Lossless Formats
Preserve perfect audio quality with no compression artifacts. Use for archiving, mastering, or when maximum quality is required.
WAV (PCM)
Uncompressed audio. Industry standard for professional production. Supports up to 32-bit float, 192 kHz.
FLAC
Lossless compression (50% file size). Perfect for archiving with quality preservation and metadata support.
AIFF
Apple's uncompressed format. Preferred for Mac/iOS workflows and professional production.
Compressed Formats
Smaller file sizes with perceptual encoding. Ideal for streaming, podcasts, and web delivery where bandwidth and storage matter.
MP3
Universal compatibility. 320 kbps for high quality, 192 kbps for good quality, 128 kbps for acceptable quality.
AAC
Better quality than MP3 at same bitrate. Preferred for Apple platforms, YouTube, and modern streaming.
OGG Vorbis
Open-source format with excellent quality-to-size ratio. Common in gaming and web applications.
Platform Optimization
Each platform has specific technical requirements and recommended settings. Wubble Studio automatically optimizes exports for your target platform:
🎵 Music Streaming (Spotify, Apple Music, Tidal)
Target: -14 LUFS integrated loudness, -1.0 dBTP true peak. Format: AAC 256 kbps or MP3 320 kbps. Sample rate: 44.1 kHz or 48 kHz.
Automatic normalization ensures consistent playback across platforms without excessive limiting.
🎙️ Podcasts (Spotify, Apple Podcasts, Google Podcasts)
Target: -16 LUFS for voice-focused content. Format: MP3 128-192 kbps (mono for voice-only, stereo for music). Sample rate: 44.1 kHz.
Optimized for speech clarity and small file sizes. Mono encoding reduces bandwidth for voice-only content.
📹 YouTube & Social Media
Target: -13 to -15 LUFS integrated loudness. Format: AAC 192-256 kbps. Sample rate: 48 kHz. True peak: -1.0 dBTP.
Balanced loudness prevents over-compression while maintaining impact for video content.
📺 Broadcast & Film
Target: -23 LUFS (EBU R128) or -24 LUFS (ATSC A/85). Format: WAV 24-bit, 48 kHz. True peak: -2.0 dBTP for safety.
Strict compliance with broadcast standards including dialogue normalization and peak limiting.
🎮 Game Audio
Format: OGG Vorbis or WAV. Sample rate: 48 kHz. Bit depth: 16-bit (OGG) or 24-bit (WAV). Loudness: varies by asset type.
Optimized file sizes for game engines with appropriate quality settings for SFX, music, and voice.
Loudness Normalization
Modern platforms normalize audio to target loudness levels. Wubble Studio measures and adjusts integrated loudness (LUFS) and true peak levels automatically to match platform requirements.
Integrated Loudness (LUFS)
Measures perceived loudness over the entire track. Most platforms target -14 to -16 LUFS. Wubble automatically adjusts gain or applies limiting to hit the target.
True Peak Limiting
Prevents inter-sample peaks that cause distortion during format conversion. Typical target: -1.0 dBTP. Ensures clean playback across all devices.
Dynamic Range Preservation
Wubble's intelligent limiting preserves dynamic range while meeting loudness targets. Avoids over-compression that flattens mixes.
Advanced Export Options
Stem Exports
Export individual tracks or groups separately for remixing, collaboration, or stems delivery to clients.
Sample Rate Conversion
Convert between 44.1, 48, 88.2, 96, and 192 kHz with high-quality resampling algorithms.
Bit Depth Conversion
Convert between 16-bit, 24-bit, and 32-bit float with proper dithering for bit depth reduction.
Metadata Embedding
Add track info, artist, album, artwork, copyright, and custom metadata to all supported formats.
Batch Rendering
Export multiple formats simultaneously. Create Spotify, Apple Podcasts, and archive versions in one operation.
Region Export
Export specific sections or regions instead of entire projects. Perfect for creating clips or samples.
Using the API
Automate exports through the Wubble Studio API. Build custom delivery pipelines, batch process multiple projects, or integrate export into your production workflow.
// Export-oriented flow using REST routes
const response = await fetch('https://prod-backup-backend.wubble.ai/v1/music/songs/remix', {
method: 'POST',
headers: {
Authorization: `Bearer ${process.env.WUBBLE_API_KEY}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({
song_id: 'song_123',
lyrics: 'Final export master',
prompt: 'Broadcast-ready output, controlled peaks, platform-safe loudness profile',
}),
});
const payload = await response.json();
console.log(payload.data.request_id);API Documentation
See the Export API Reference for complete documentation of export formats, platform presets, and rendering options.
Best Practices
Match Platform Requirements
Use platform-specific presets to ensure compliance with technical specifications. This prevents playback issues and maintains consistent loudness across platforms.
Master in High Resolution
Work at 48 kHz or 96 kHz, 24-bit or 32-bit float. Export high-res masters for archiving, then create delivery versions from those masters.
Check Loudness Before Export
Use integrated loudness metering to verify your mix hits target LUFS before final export. Make adjustments in the mix rather than relying only on limiting.
Include Proper Metadata
Always embed metadata: artist, title, album, copyright, and genre. This ensures proper attribution and makes content management easier across platforms.
Use Batch Exports
When delivering to multiple platforms, use batch export to create all versions simultaneously. Saves time and ensures consistency across deliverables.
Test on Target Devices
Listen to final exports on intended playback systems: headphones, phone speakers, car audio. Ensure quality translates across all listening environments.
Archive High-Quality Masters
Keep WAV or FLAC masters at highest resolution. Platform requirements change over time—having high-quality masters lets you re-export without quality loss.
