frequencies is short. This is called temporal masking. By removing all frequencies that are masked, the ones with low energy, the information amount is reduced without effecting our interpretation of the sound.

This is one way to lossy compression sound. Temporal masking: • Temporal masking is defined as process by which redundant data in sound speech like pauses, longer length alphabets like F, S is masked in time domain. • Disadvantages of Temporal masking: o Designing of system is complex because of convolution process.
