320 vs 128 kbps
| 128 kbps | 320 kbps | |
|---|---|---|
| Size per minute | ~1 MB | ~2.4 MB |
| One-hour file | ~60 MB | ~144 MB |
| Speech (talks, podcasts) | Sounds the same | Sounds the same |
| Music and sound design | Small loss in cymbals and reverb tails | As close to the source as MP3 gets |
Rule of thumb: voices → 128 kbps; music and anything you'll listen to closely → 320 kbps.
Where the sound comes from
YouTube doesn't store a 320 kbps MP3. It streams audio in AAC or Opus at roughly 128–160 kbps. When you convert, our server takes that stream and encodes it to MP3 at the bitrate you choose. A higher MP3 bitrate means less extra loss during that conversion — it can't bring back detail that YouTube's stream never had. If you need audio with no extra compression at all, use YouTube to WAV instead.
Good uses for a 320 kbps MP3
- Music from artists who publish free downloads or Creative Commons tracks.
- Your own channel's soundtrack or voice-over, kept as a high-quality backup.
- Field recordings and ambient sound for personal listening.
