Question
Calculate how much storage space is needed to record a 32- bit, 7 khz, stereo music for a duration of 1 hour. (Give in bytes: put the value without symbol)
Solution 1
To calculate the storage space needed, we need to use the formula:
Storage Space = Bit Depth * Sample Rate * Channels * Time
where:
- Bit Depth is the number of bits in each sample, which is 32 bits in this case.
- Sample Rate is the number of samples per second, which is 7,000 (or 7 kHz) in this case.
- Channels is the number of separate audio signals, which is 2 for stereo sound.
- Time is the duration of the audio in seconds. Since we're looking for an hour, this would be 60 minutes * 60 seconds = 3,600 seconds.
So, the calculation would be:
Storage Space = 32 bits/sample * 7,000 samples/second * 2 * 3,600 seconds
This gives us the total storage space in bits. However, we want the answer in bytes, and there are 8 bits in a byte. So, we divide the total by 8 to convert from bits to bytes:
Storage Space = (32 * 7,000 * 2 * 3,600) / 8 bytes
When you calculate this, you get 3,168,000,000 bytes.
Solution 2
To calculate the storage space needed, we need to use the formula:
Storage Space = Bit Depth * Sample Rate * Channels * Time
where:
- Bit Depth is the number of bits in each sample, which is 32 bits in this case.
- Sample Rate is the number of samples per second, which is 7,000 (or 7 kHz) in this case.
- Channels is the number of separate audio signals, which is 2 for stereo sound.
- Time is the duration of the audio in seconds. Since we're looking for an hour, this would be 60 minutes * 60 seconds = 3,600 seconds.
So, the calculation would be:
Storage Space = 32 bits/sample * 7,000 samples/second * 2 * 3,600 seconds
This gives us the total storage space in bits. However, we want the answer in bytes, and there are 8 bits in a byte. So, we divide the total by 8 to convert from bits to bytes:
Storage Space = (32 * 7,000 * 2 * 3,600) / 8 bytes
Let's calculate that:
Storage Space = 3,168,000,000 bytes
So, you would need approximately 3,168,000,000 bytes of storage space to record a 32-bit, 7 kHz, stereo music for a duration of 1 hour.
Solution 3
To calculate the storage space needed, we need to use the formula:
Storage Space = Bit Depth * Sample Rate * Channels * Time
where:
- Bit Depth is the number of bits in each sample, which is 32 bits in this case.
- Sample Rate is the number of samples per second, which is 7 kHz or 7000 samples per second.
- Channels is the number of separate audio signals, which is 2 for stereo.
- Time is the duration of the audio in seconds. 1 hour is 3600 seconds.
So, the storage space needed is:
Storage Space = 32 bits/sample * 7000 samples/second * 2 * 3600 seconds
However, the result of this calculation will be in bits. Since 1 byte = 8 bits, we need to divide the result by 8 to convert it to bytes.
Let's calculate:
Storage Space = (32 * 7000 * 2 * 3600) / 8
Storage Space = 20160000000 bytes
So, you would need 20160000000 bytes of storage space to record a 32-bit, 7 kHz, stereo music for a duration of 1 hour.
Solution 4
To calculate the storage space needed, we need to use the formula:
Storage Space = Bit Depth * Sample Rate * Channels * Time
where:
- Bit Depth is the number of bits in each sample, which is 32 bits in this case.
- Sample Rate is the number of samples per second, which is 7,000 (7 kHz) in this case.
- Channels is the number of separate audio signals, which is 2 (stereo) in this case.
- Time is the duration of the audio in seconds. Since we have 1 hour, and there are 3600 seconds in an hour, the time is 3600 seconds.
So, the calculation would be:
Storage Space = 32 bits/sample * 7,000 samples/second * 2 * 3600 seconds
However, the result of this calculation will be in bits. Since 1 byte = 8 bits, we need to divide the result by 8 to convert it to bytes.
Let's do the calculation:
Storage Space = (32 * 7,000 * 2 * 3600) / 8
Storage Space = 1008,000,000 bytes
So, you would need 1008,000,000 bytes of storage space to record a 32-bit, 7 kHz, stereo music for a duration of 1 hour.
