1. Determine the duration of audio playback (Tpl) of a mono .wav file having with the specified size
of audio data block and bit rate. Show your work.
Size: 1.3 MB
Bitrate: 176.4 kbps
To determine the duration of audio playback, we need to calculate the total audio data size first.
Given:
Size of audio data block = 1.3 MB
Bitrate = 176.4 kbps
Step 1: Convert the size from MB to bits
1 MB = 8,000,000 bits (since 1 byte = 8 bits)
So, the size of audio data block in bits = 1.3 MB * 8,000,000 bits/MB = 10,400,000 bits
Step 2: Calculate the duration of audio playback
Duration (in seconds) = Total audio data size (in bits) / Bitrate (in bits per second)
Duration (in seconds) = 10,400,000 bits / 176,400 bits per second = 58.98 seconds
Therefore, the duration of audio playback (Tpl) for the given .wav file is approximately 58.98 seconds.
