What fits in 10 MB
Audio size is bitrate × length, so 10 MB buys a different quality depending on how long the recording is.
| Length | Bitrate | Realistic quality |
|---|---|---|
| 1 min | 1.3 Mbps | Excellent: as good as the source |
| 3 min (a song) | 444 kbps | Excellent: as good as the source |
| 10 min | 133 kbps | Good music quality |
| 30 min | 44 kbps | Speech only |
| 1 h | 22 kbps | Low-quality speech |
Rough guide for MP3/AAC. A file is never made better than its source, so high-bitrate rows just keep the original quality.
What 10 MB is typically for
- Podcast episodes and lectures at speech-friendly bitrates

Limits vary by site and change over time; check the exact number where you're uploading.
