Memory

 

As mentioned earlier, more accurate sampling requires more memory. Just how much of an impact does this really make? The table below shows how much memory, in MB, is required for a sampled 1-minute signal at some common sample rates and resolutions. Note the variance in required memory between the lowest-quality and highest-quality samples:

Sample Rate

8-Bit Resolution

16-Bit Resolution

8 kHz (mono)

0.47

0.94

22.05 kHz (mono)

1.29

2.58

44.1 kHz (mono)

2.58

5.17

44.1 kHz (stereo)

5.17

10.34
