WBL2 (Wubble audio archive)
Business and Enterprise users can choose WBL2 for individual tracks and collections. Recommended for playlist archiving with a WBL2-compatible reader. Collections share duplicate audio and use lossless residuals only when smaller; every exported track is verified before delivery. Savings vary by audio.
- Choose WBL2 in the existing Download audio-format selector. A single track saves as .wbl; a playlist ZIP contains collection.wbl and any chosen sidecars.
- Restore with a WBL2-compatible reader. Use MP3 or WAV for direct playback or editing in other software.
- Exported audio is 16-bit mono/stereo at 8–192 kHz. Higher bit depths are converted; original file tags and container bytes are not preserved.
- Limits: 40 MiB source and decoded audio per track; 12 tracks and 96 MiB total source and decoded audio per collection.
- Normal download credits apply after verification. WBL2 is an audio archive, not a .wubble project file.
WAV (Waveform Audio File Format)
WAV is an uncompressed, lossless audio format that maintains the highest quality. It's the industry standard for professional audio production, mastering, and archival purposes. WAV files are large but preserve every detail of your audio.
- Best for: Professional production, mastering, archival, and when quality is paramount
- File size: Very large (approximately 10MB per minute of stereo audio at 44.1kHz)
- Quality: Lossless, maximum quality
- Compatibility: Universally supported by all audio software and hardware
- Recommended sample rate: 44.1kHz for music, 48kHz for video/film
FLAC (Free Lossless Audio Codec)
FLAC is a compressed lossless format that maintains perfect audio quality while reducing file size by 40-50% compared to WAV. It's ideal when you need high quality but want to save storage space.
- Best for: High-quality archival, distribution to audiophiles, personal music libraries
- File size: Medium (approximately 5-6MB per minute)
- Quality: Lossless, identical to WAV
- Compatibility: Supported by most modern players and software
- Recommended for: Long-term storage when space is a concern
MP3 (MPEG Audio Layer 3)
MP3 is a lossy compressed format that reduces file size significantly by removing audio information that's less perceptible to human hearing. It's the most widely compatible format for consumer use.
- Best for: Web streaming, podcasts, social media, general distribution
- File size: Small (approximately 1MB per minute at 128kbps, 2.5MB at 320kbps)
- Quality: Good to excellent depending on bitrate (192-320kbps recommended)
- Compatibility: Universal support on all devices and platforms
- Recommended bitrate: 320kbps for music, 192kbps for podcasts and speech
AAC (Advanced Audio Coding)
AAC is a modern lossy format that offers better sound quality than MP3 at the same bitrate. It's the standard format for Apple devices, YouTube, and many streaming services.
- Best for: Apple ecosystem, YouTube, streaming services, mobile devices
- File size: Small (similar to MP3 but better quality at same bitrate)
- Quality: Better than MP3 at equivalent bitrates
- Compatibility: Excellent, especially on Apple devices and modern platforms
- Recommended bitrate: 256kbps for music, 128kbps for speech
OGG Vorbis
OGG Vorbis is an open-source lossy format that offers quality comparable to AAC. It's commonly used in gaming, open-source software, and web applications.
- Best for: Game development, open-source projects, web applications
- File size: Small (comparable to MP3 and AAC)
- Quality: Comparable to AAC at similar bitrates
- Compatibility: Good support in modern browsers and gaming platforms
- Recommended for: Gaming audio, web apps, and when open-source is preferred
