A digital audio engineer is modifying the recording settings for a soundtrack. They decide to double the sampling rate of the audio while halving the sample resolution (bit depth).
Which of the following correctly describes the combined effect of these changes on the file size of the recording and its audio characteristics (assuming duration and channel count remain constant)?
The overall file size remains unchanged; the precision of the amplitude representation is reduced, but a wider range of frequencies can be captured.
The overall file size is halved; the precision of the amplitude representation is reduced, and the range of frequencies that can be captured remains unchanged.
The overall file size remains unchanged; the precision of the amplitude representation is increased, but the range of frequencies that can be captured is halved.
The overall file size is doubled; the precision of the amplitude representation remains unchanged, but a wider range of frequencies can be captured.
