Question

Based on this week's reading, calculate the amount of uncompressed AIFF audio (in time - like, how many minutes, or hours) you could record to a 1GB hard drive if you sampled the audio at 44.1kHz (CD-quality), 16 bit, stereo file.

a. True
b. False

Answer 1

With a sample rate of 44.1kHz, 16-bit depth, and stereo channels, approximately 99 minutes of uncompressed CD-quality AIFF audio can be stored on a 1GB hard drive.

Step-by-step explanation:

To calculate the amount of uncompressed AIFF audio you could store on a 1GB hard drive with a sample rate of 44.1kHz, 16-bit depth, and stereo channels, the following formula can be used:

1. First, calculate the bit rate: 44.1kHz * 16 bits * 2 (for stereo) = 1,411.2 kbits/second.
2. Convert the bit rate to bytes per second: 1,411.2 kbits/second / 8 = 176.4 KB/second.
3. Since 1GB = 1,024MB and 1MB = 1,024KB, convert gigabytes to kilobytes: 1GB = 1,024 * 1,024KB = 1,048,576KB.
4. Finally, divide the total kilobytes by the kilobytes per second to get the total seconds of audio: 1,048,576KB / 176.4 KB/second ≈ 5,946 seconds.
5. To get this in minutes, divide by 60: 5,946 seconds / 60 ≈ 99.1 minutes.

Therefore, you could record approximately 99 minutes of uncompressed AIFF audio at CD quality on a 1GB hard drive.
