What to check
After your application has processed sample-mp3-1-minute.mp3, confirm that:
- The duration is reported as 1:00, to within a tenth of a second.
- Seeking to 0:30 lands half-way through, which holds for constant-bit-rate audio without a seek table.
- The title from the ID3 tag is shown instead of the file name.
