A musician is looking to digitise a song from their record collection and is trying to establish how much space the sound file will take up on a portable hard drive. For recording the sound file, they are looking to use a sampling rate of 44 kHz with each sample being 4 bytes, initially on a single channel (mono).i.How many bits are there in each sample?

A typical sampling rate is 44.1 kHz and there are typically 16 bits in each sample. How many bits per second are processed? Express your answer in scientific notation.

In digital audio, ----------------- describes the number of bits of information recorded for each sample.

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)Answer:

What is the percentage increase in the number of bits processed as a result of increasing the sampling rate from 44 kHz to 128 kHz? Express your answer to the nearest percent.

We want to digitise an analogue signal with bandwidth 6 kHz and will be using a quantiser that allows one of 256 possible levels. Approximately what bit rate (in kbit/s) do you think we should expect after sampling and quantisation? (Give the number of kbit/s ONLY - do not show your calculation and do not include units.)
