During the playback phase, the file is taken from memory, decoded by the DSP and then converted back to an analog signal through the digital-to-analog converter so it can be output through the speaker system. In a more complex example, the DSP would perform other functions such as volume control, equalization and user interface.

A DSP's information can be used by a computer to control such things as security, telephone, home theater systems, and video compression. Signals may be compressed so that they can be transmitted quickly and more efficiently from one place to another e. Signals may also be enhanced or manipulated to improve their quality or provide information that is not sensed by humans e. Although real-world signals can be processed in their analog form, processing signals digitally provides the advantages of high speed and accuracy.

This allows a user to connect microphones directly into a DSP appliance, without needing a separate device. Without echo cancellation, your voice would be amplified on the other party's system "the far end" , get picked up by their microphone, and then play back again on your speakers. AEC subtracts that audio from the microphone's signal before any echo can occur.

Automatic Gain Control: Next, the DSP system automates and balances the volume throughout a conference, so that the signal never gets too loud or too quiet.

This can dramatically reduce audio fatigue. Gating: Some DSP systems can distinguish between voices and unwanted noise, such as crinkling paper and footsteps. When any noise is picked up by a microphone, the DSP algorithm will "gate" i.
