Which quality to choose (and how big it’ll be)
| Use | MP3 (kbps) | Approx. size per minute | Notes |
|---|---|---|---|
| Voice note / dictation | 64 | ~0.47 MB | Smallest size; ideal for long audios. |
| Clear voice (recommended) | 128 | ~0.94 MB | Great quality/size balance. |
| Voice + prominent music | 192 | ~1.41 MB | More headroom for editing and music. |
Pro tips for better results
- Normalize volume after converting to MP3 if the note is quiet (Audacity or another editor).
- Mono vs. Stereo: for speech, mono + 64–128 kbps saves space without losing clarity.
- Large files by email: if they exceed 25 MB, upload to Drive/Dropbox and share the link.
- Organization: rename with date + topic:
2025-08-28-voice-note-meeting.mp3. - Privacy: files are processed only for conversion and are automatically deleted after completion.
Common errors & how to fix them
- Can’t find the .opus file: search for “*.opus” in the file manager or check the “Downloads” folder.
- Doesn’t play in the car/TV: many units don’t read OPUS; convert to MP3.
- Very low volume: convert to MP3 and then increase the level in an editor. Avoid over-amplifying to prevent distortion.
- MP3 too large: use 64–128 kbps (voice) or try MP3 → smaller MP3.
