Sample OGG Vorbis Files
Open-source, royalty-free lossy audio — better quality than MP3 at the same bit rate. Our OGG collection includes 8 files at bit rates from 64 kbps to 320 kbps. OGG Vorbis is natively supported in Chrome, Firefox, and Edge, and is the preferred audio format for game engines like Unity, Godot, and Unreal Engine.

|---|---|---|
| Voice recording | 64 kbps | 0:20 |
| Music (128 kbps) | 128 kbps | 0:30 |

| Music (320 kbps) | 320 kbps | 0:30 |
Sample M4A (AAC) Files
AAC audio in the MPEG-4 container — the standard format for Apple Music, iTunes, YouTube, and most streaming platforms. Our M4A collection includes 7 files at bit rates from 48 kbps to 256 kbps. AAC delivers better quality than MP3 at the same bit rate and has near-universal platform support across iOS, Android, and all major browsers.
| Quick Downloads | Bit Rate | Duration |
|---|---|---|
| Low bitrate | 48 kbps | 1:00 |
| Voice recording | 96 kbps | 0:30 |
| Music (256 kbps) | 256 kbps | 1:00 |
| Long audio | 192 kbps | 5:00 |
Sample WMA Files
Microsoft’s proprietary audio codec — essential for testing Windows compatibility, legacy applications, and enterprise media systems. Our WMA collection includes 5 files at bit rates from 64 kbps to 192 kbps. While WMA is no longer the dominant format, it remains important for kiosk systems, archived media libraries, and legacy Windows application testing.
| Quick Downloads | Bit Rate | Duration |
|---|---|---|
| Voice recording | 64 kbps | 0:30 |
| Music (128 kbps) | 128 kbps | 1:00 |
| Long audio | 96 kbps | 5:00 |
Audio format comparison
Not sure which format to use for testing? This comparison table summarizes the key differences:
| Format | Compression | Quality | File Size (1 min stereo) | Best For |
|---|---|---|---|---|
| WAV | None (uncompressed) | Lossless — reference quality | ~10 MB (44.1 kHz/16-bit) | Production, mastering, reference source |
| FLAC | Lossless | Lossless — identical to WAV | ~5 MB (44.1 kHz/16-bit) | Archival, audiophile, lossless distribution |
| MP3 | Lossy | Good to excellent (128–320 kbps) | ~1–2.5 MB | Web streaming, widest compatibility |
| M4A (AAC) | Lossy | Better than MP3 at same bit rate | ~1–2 MB | Apple ecosystem, streaming, mobile |
| OGG Vorbis | Lossy | Better than MP3 at same bit rate | ~0.8–1.8 MB | Web, games, open-source projects |
| WMA | Lossy | Comparable to MP3 | ~1–1.5 MB | Windows legacy, enterprise systems |
Which format should you download?
The right format depends on your testing scenario:
- Testing a web audio player? Start with MP3 (universal support) and OGG (open-source fallback for HTML5 <audio>).
- Building a mobile app? Use M4A (AAC) for the best quality-to-size ratio on iOS and Android.
- Testing codec quality or conversion? Start with WAV or FLAC as your lossless source, then convert to lossy formats.
- Working with game audio? Use OGG Vorbis — it’s the standard for Unity, Godot, and Unreal Engine.
- Testing Windows compatibility? Use WMA for Windows Media Player and legacy system validation.
- Need a lossless format for archival? Use FLAC — same quality as WAV at half the file size.
- Testing upload forms? Download files from multiple formats and sizes to verify MIME type validation and file size limits.

FAQs about sample audio files
What is the best audio format for testing?
It depends on what you’re testing. For general playback testing, MP3 is the safest choice due to universal compatibility. For quality-sensitive testing, use WAV or FLAC as your lossless reference and compare against lossy conversions. For web and mobile, test with both MP3 and M4A (AAC) to cover all browsers and devices. For game development, OGG Vorbis is the standard. For Windows-specific testing, include WMA files in your test suite.
What is the difference between lossy and lossless audio?
Lossy formats (MP3, AAC/M4A, OGG, WMA) permanently discard audio data to achieve small file sizes. The discarded data is chosen to minimize audible impact, but quality loss is measurable and cumulative with re-encoding. Lossless formats (WAV, FLAC) preserve every bit of the original audio — WAV stores it uncompressed, while FLAC compresses it without any data loss. Lossless files are larger but produce identical output to the original recording.
What do sample rate and bit depth mean?
Sample rate (kHz) is how many times per second the audio is captured — 44.1 kHz is CD standard, 48 kHz is broadcast/video standard, 96 kHz is high-resolution. Bit depth determines the dynamic range — 16-bit gives 96 dB (CD quality), 24-bit gives 144 dB (studio quality). Higher values mean better quality but larger files. Our WAV and FLAC collections include files at multiple sample rates and bit depths so you can test each configuration.
Can I convert between audio formats?
Yes. Tools like FFmpeg, Audacity, VLC, and dBpoweramp can convert between any audio format. For best results, always start from a lossless source (WAV or FLAC) when creating lossy files. Converting between two lossy formats (e.g., MP3 to OGG) causes additional quality loss because each encoding discards different audio data.
Are these audio files safe to download?
Yes, all sample audio files on this site are clean, verified, and free of malware. They are standard audio files containing no executable code, no DRM restrictions, and no tracking. Every file is safe for use in any development, testing, or production environment.
Can I use these files for upload form testing?
Yes — that’s one of the most common use cases. Our audio files range from 8 KB (OGG silence) to 50 MB (5-minute WAV), covering a wide range of file sizes for testing upload limits. Each format has a different MIME type (audio/mpeg, audio/wav, audio/flac, audio/ogg, audio/mp4, audio/x-ms-wma), so you can verify your application’s MIME type validation across all common audio formats.
