Free Audio Test Files for Developers
Download high-quality sample audio files in MP3, WAV, and OGG formats. Perfect for testing audio players, streaming applications, mobile apps, audio processing APIs, and CDN audio delivery. All files are free, safe, and ready for production testing.
Why Use Audio Test Files for Development & Testing
Audio test files are essential for validating audio players, streaming services, mobile apps, and audio processing systems. Our sample files help you test real-world scenarios without copyright concerns.
Audio Player & Streaming App Testing
Test audio playback functionality, seek operations, buffering behavior, and streaming performance with real audio files. Validate that your audio player handles different formats (MP3, WAV, OGG) correctly, displays metadata accurately, and provides smooth playback across devices.
Mobile App Audio Upload Testing
Validate mobile app file upload functionality with audio files. Test upload limits, progress indicators, format validation, and error handling. Ensure your app correctly handles audio file uploads on iOS and Android, including background uploads and network interruption recovery.
Audio Processing API Validation
Test audio processing APIs, format conversion services, and audio analysis tools. Validate that your API correctly handles audio file uploads, extracts metadata (duration, bitrate, sample rate), performs format conversions, and processes audio data without errors.
CDN Audio Delivery Testing
Test how your Content Delivery Network handles audio file delivery. Validate caching behavior, edge location performance, and streaming capabilities. Ensure your CDN correctly serves audio files with proper MIME types, supports range requests for seeking, and maintains consistent performance across regions.

Frequently Asked Questions about Audio Test Files
Common questions about using audio files for testing and development
What audio formats are available for testing?
We offer audio test files in three popular formats: MP3 (compressed, web-friendly, 2.5-4.3 MB), WAV (uncompressed, lossless quality, 11-15 MB), and OGG (open-source, modern web standard, 3.6-4.7 MB). Each format serves different testing purposes: MP3 for general playback and streaming, WAV for audio editing and professional workflows, OGG for open-source projects and modern browser compatibility.
Can I use these audio files to test my mobile app's audio upload functionality?
Absolutely! Our audio test files are perfect for testing mobile app audio upload functionality. Use MP3 files (2.5-4.3 MB) for quick upload tests on slower networks, or WAV files (11-15 MB) to test upload limits and progress indicators. These files help you validate format detection, file size limits, upload progress bars, error handling, and network interruption recovery on both iOS and Android platforms.
How do I test audio streaming performance with these files?
To test audio streaming performance, use our MP3 files (2.5-4.3 MB) which are optimized for streaming. Test buffering behavior, seek operations (jumping to different positions), adaptive bitrate logic, and CDN edge delivery. Monitor metrics like Time-To-First-Byte (TTFB), buffering duration, and playback smoothness. For testing range requests (HTTP 206 Partial Content), use WAV files which are larger and better for validating seek functionality.
Are these audio files safe to use in production testing environments?
Yes, absolutely! All our audio test files are 100% safe and free for commercial use. They contain no copyrighted content, no malware, and no executable code. Perfect for production testing, staging environments, CI/CD pipelines, and QA validation. No attribution required. Use them to test audio players, streaming services, mobile apps, and audio processing systems without any legal concerns.
What's the difference between MP3, WAV, and OGG formats for testing?
MP3 (2.5-4.3 MB) is compressed and web-friendly—use for general playback testing, streaming apps, and mobile apps. WAV (11-15 MB) is uncompressed and lossless—use for audio editing software testing, professional workflows, and validating high-quality audio processing. OGG (3.6-4.7 MB) is open-source and modern—use for testing open-source projects, modern browser compatibility, and HTML5 audio elements. Choose based on your specific testing needs.
Can I use these files to test audio processing APIs and format conversion?
Yes! Our audio files are perfect for testing audio processing APIs. Use them to validate: format detection (ensuring your API correctly identifies MP3, WAV, OGG), metadata extraction (duration, bitrate, sample rate), format conversion (MP3 to WAV, OGG to MP3, etc.), and audio analysis (waveform generation, audio fingerprinting). The variety of formats and sizes helps you test edge cases and ensure your API handles all scenarios correctly.
