Common mistakes with 3GP files
| What goes wrong | Effect | What to do |
|---|---|---|
| Sending a 3GP clip made with a muffled phone mic | Words are unclear, so the summary is incomplete | Record the 3GP clip closer to the speaker |
| Expecting a detailed summary from a very short 3GP clip | Short clips give only one or two points | Combine related clips in your own notes |
| Checking only the summary and skipping the 3GP speech | Names and places may be shortened | Read the transcript for exact names |
| Sending a 3GP recorded in a loud street | Traffic dominates the audio, so the digest stays thin | Move indoors or record again closer to the speaker |
