What is a 10MB AAC file useful for?
A 10 MB AAC file at 128 kbps provides approximately 11 minutes of audio — a full podcast episode segment, a long-form interview clip, or a complete album track in AAC format. Use it to test that your audio upload pipeline enforces a file-size limit before processing, that async waveform generation handles long audio correctly, and that your CDN serves AAC content with Accept-Ranges headers for in-browser seek support.
