The dead(empty) spaces on the audio come up in between the recording. How do you account for this?

If the dead spaces happen in between the recording, you can take the total of all the occurrences of empty recording on the audio and and update the cart with the actual play time duration. This will allow you to pay only for the actual audio duration that is being transcribed. However, please note that there needs to be a minimum of one running minute of empty recording each time and you will have to provide us with the start and end time of each dead space on the audio.
