When transcribing multiple files, each file is always processed separately and the duration of each file is rounded up to the next minute.
For example, transcribing the following files would result in 8 (not 7) minutes being deducted from your account balance:
- 1m10s (rounded up = 2m00s)
- 2m50s (rounded up = 3m00s)
- 2m30s (rounded up = 3m00s)
