Audio Format Considerations
Different audio formats offer different advantages. Understanding format trade-offs helps you choose the right option for your QR code campaigns.

- •AAC: Better quality than MP3 at same bitrate, excellent for speech-heavy content like podcasts and audiobooks.
- •WAV/FLAC: Lossless formats offer maximum quality but create very large files. Only use when audio quality is paramount.
- •OGG Vorbis: Open-source format with good quality and compression, though less universally supported than MP3.
Frequently Asked Questions
Does QR Hideout show ads after scanning?
Never. QR Hideout generates static QR codes that go directly to your audio content with zero ads, redirects, or tracking. When someone scans your audio QR code, they go straight to your audio file or streaming platform. No interstitial ads, no waiting, no data collection.
What's the difference between static and dynamic QR codes?
Static QR codes encode data directly in the code itself. They work forever, even offline, and never expire. Dynamic QR codes require a server redirect, where competitors often show ads or track users. QR Hideout creates static QR codes, so your audio QR codes will work even if our website goes offline.
What audio file formats work with QR codes?
Audio QR codes work with any audio URL regardless of format. You can link to streaming platforms, direct MP3/WAV/AAC/OGG files, or any web-based audio player. The QR code simply opens the URL, and the listener's device handles playback. MP3 is the safest format for maximum compatibility across all devices.
Do listeners need special apps to play audio from QR codes?
No special apps are required. QR codes open audio URLs in the device's web browser, which has built-in audio playback capabilities. Platform-specific apps (like SoundCloud or podcast apps) may automatically open if installed, but audio will play in browsers otherwise. Ensure your audio player is mobile-friendly.
Can I track how many people listen to audio from my QR code?
Most audio hosting platforms provide analytics showing plays, listen duration, and listener locations. For more precise tracking, use our branded splash screen feature or URL shorteners with analytics before generating QR codes. This lets you differentiate QR code listens from other traffic sources.
Will my QR code break if I delete the audio file?
Yes, static QR codes link directly to the audio URL. If you delete the file or change its location, the QR code will no longer work. Use stable audio hosting platforms that allow file replacement without URL changes. For permanent materials, choose audio files you plan to keep accessible indefinitely.
Do audio QR codes work without internet?
The QR code can be scanned offline, but playing streaming audio requires an internet connection. If targeting locations with poor connectivity, consider shorter audio files that load quickly or inform users to download for offline listening. Some advanced implementations might link to downloadable files, but streaming is standard.
What's the ideal length for audio linked to QR codes?
Keep audio concise when possible. Promotional content should be 30-90 seconds. Product descriptions and testimonials work well at 1-3 minutes. Educational content and podcast episodes can run longer (20-60 minutes) since listeners specifically seek that content. Always prioritize value over length.
Should I use SoundCloud, direct files, or podcast hosting?
SoundCloud offers free hosting, social features, and built-in analytics. It's great for musicians and independent creators. Podcast hosting (Libsyn, Buzzsprout) provides RSS feeds and platform distribution. Direct files give maximum control but require web hosting and bandwidth. Choose based on your content type and distribution needs.
Can I add audio QR codes to product packaging?
Absolutely! Product packaging is perfect for audio QR codes. Link to audio instructions, brand stories, customer testimonials, or product demonstrations. Print QR codes directly on packaging, include them on inserts, or add stickers. Ensure minimum 2x2 cm size and high contrast for reliable scanning.
How can I make my audio accessible?
Provide text transcripts alongside audio for hearing-impaired users and those who prefer reading. Include descriptive titles that explain audio content. Ensure audio players have visible play/pause controls and progress indicators. For multilingual audiences, offer audio in multiple languages via different QR codes.
How large should I print audio QR codes?
Minimum 2x2 cm (0.8x0.8 inches) for close-range scanning on business cards, packaging, or name tags. For posters, museum placards, or signage scanned from a distance, use 4x4 inches or larger. Follow the 10:1 rule: maximum scanning distance equals 10x the QR code width. Test printed codes before mass production.
