Determine duration of playback of mono .wav file with the following characteristics:

- size of audio data block: 356402 bytes;
- sampling rate: 44100 Hz;
- resolution: 16-bits.

To determine the duration of playback of a mono .wav file with these characteristics, you can use the following formula:

Duration = (Size of audio data block) / (Sampling rate x Resolution x Number of channels)

In this case, as the file is mono, the number of channels is 1. Plugging in the values given:

Duration = 356402 / (44100 x 16 x 1) = 1.60 seconds (rounded off to two decimal places)

Therefore, the duration of playback of this mono .wav file is approximately 1.6 seconds.
