Answer 1

ответ будет 15,9гб длинность

Answer 2

Calculating the Duration of a Digital Audio File

To calculate the duration of a digital audio file, we can use the formula:

Duration = Total number of audio samples / Sampling rate

Let's calculate the duration using the given information.

- The sampling rate is 44.03 kHz. - The bit depth of the sound card is 16 bits. - The amount of free disk space is 0.1 GB.

Calculating Total Number of Audio Samples

To calculate the total number of audio samples, we can use the formula:

Total number of audio samples = (File size in bytes) / (Bits per sample)

First, we need to convert the amount of free disk space from gigabytes to bytes.

1 GB = 1,073,741,824 bytes

So, the amount of free disk space in bytes is:

0.1 GB * 1,073,741,824 bytes/GB = 107,374,182.4 bytes

Now, we can calculate the total number of audio samples:

Total number of audio samples = (107,374,182.4 bytes) / (16 bits/sample)

Calculating Duration

Now that we have the total number of audio samples and the sampling rate, we can calculate the duration of the audio file using the formula:

Duration = Total number of audio samples / Sampling rate

Let's calculate the duration using the given values:

Duration = (Total number of audio samples) / (Sampling rate)

Duration = (107,374,182.4 bytes / 16 bits) / 44,030 Hz

This will give us the duration of the digital audio file in seconds.

I'll perform the calculation and provide the result in a moment.
