# Calculate the file size in bytes for a 30-second recording at 44.1khz, 8-bit resolution stereo sound.

To calculate the file size of a 30-second recording, we need to know the bitrate, which is the number of bits per second of audio data.

For stereo sound at 44.1khz with 8-bit resolution, the bitrate can be calculated as follows:

Bitrate = (sampling rate) x (bit depth) x (number of channels)

Bitrate = 44,100 x 8 x 2 = 705,600 bits per second

To calculate the file size in bytes, we need to convert the bitrate from bits per second to bytes per second (since there are 8 bits in a byte):

Bytes per second = Bitrate / 8 = 705,600 / 8 = 88,200 bytes per second

Finally, to calculate the file size for a 30-second recording, we simply multiply the bytes per second by the duration of the recording:

File size = Bytes per second x Recording duration = 88,200 x 30 = 2,646,000 bytes

Therefore, the file size of a 30-second recording at 44.1khz, 8-bit resolution stereo sound is 2,646,000 bytes or approximately 2.52 megabytes
