Use this catalog when you need ready-to-use sample audio for HTML5 players, upload forms, decoder pipelines, streaming demos, or QA scenarios. Every entry is either hosted by AppKiro itself or curated from stable public sources that allow direct hot-linking and download.
Combine the duration and file size filters to test small uploads (under 100 KB), normal uploads (1–5 MB), or stress scenarios (over 20 MB). The size column shows the actual encoded byte length.
Use MP3 for broad playback, WAV for lossless reference, OGG for open-codec fallbacks, M4A or AAC for Apple workflows, and FLAC when you need a high-fidelity long-form file.
The Genre / Type filter separates music, speech, sound effects, instrumental, and test tones so you can validate transcription, ASR, music recognition, or simple beep playback.
Use the link icon to copy the absolute URL — AppKiro library files copy as appkiro.com URLs, public files copy as their original third-party URL. Use the download icon to save the file, and the open-in-tab icon for sources that prefer inline preview.
<audio> playback across MP3, WAV, OGG, M4A, AAC, and FLAC.Public hosts are stable but not under our control. For production traffic, CI workflows, or anything that must run for years, mirror the file to your own object storage and keep the original link as a fallback reference. AppKiro library files are guaranteed to remain available alongside this tool.
Most entries are public test samples, public-domain (CC0), or Creative Commons content from W3Schools, MDN, samplelib, learningcontainer, kozco, the Internet Archive, Wikimedia Commons, and the AppKiro local library. They are intended for demos, prototypes, QA, and tutorials. For production traffic, mirror the file to your own storage and verify the license at the source page.
Duration and bitrate are taken from the encoded file metadata. A few sources omit precise headers, so the numbers shown are best estimates. Use the inline player to verify before relying on the value.
Browsers ignore the download attribute on cross-origin URLs unless the host returns Content-Disposition. If the file plays inline, right-click the player and choose Save audio as… or use the Open icon, which opens the URL in a new tab so you can save it.
AppKiro local files are served from the same domain, so cross-origin restrictions do not apply. Direct download works without proxying. Internet samples are linked as-is from their original hosts.
Click the link icon on any row to copy the absolute URL into your clipboard. AppKiro library entries copy as fully-qualified appkiro.com URLs that you can paste into API payloads, documentation, or `<audio src=...>` tags.
