This is a 247 KB sample AAC file — exactly 247,025 bytes, generated by us rather than scraped, so the size is deliberate and the contents are free of anyone else's copyright. 15s • ADTS 128 kbps (15 s · AAC · 131 kbps · 44.1 kHz · stereo). Use it to test an upload limit near 247 KB, to time a transfer, or as a fixture whose hash never changes.
Sizes here are decimal: 247 KB means 247,025 bytes, not 0.24 MiB. If your limit is expressed in binary units, check the exact byte count above before assuming this file is under it.

What can I test with a 247 KB AAC file?
Upload size limits that sit near 247 KB, transfer timing, storage quotas, and any pipeline that behaves differently above or below a size threshold. Pick the file just under and just over your limit to find out whether the limit is inclusive.
