Meaning Of DSP

DSP is the short for ( Digital Signal Processing). The DSP cuts across audio signals to get a particular achievement. Majority of the DSP system can function with video. The DSP means positioning an audio signal in the direction of a computer based processing algorithm so as to change the features of the signal frequency.

For instance, a DSP system has the probability to add an algorithm that knows the source of a primary audio and also keeps it from a dejected noise so as to enable the audibility of the signal. More than one algorithm has the tendency of processing the audio all at a time, based on the actual signal used.

The moment the audio signal is processed, it is changed to the analog system and transferred to the speakers. The DSP is majorly used in areas like speech processing, voice recognition as well as audio signal. All Channel Stereo Mode being one of the mode of DSP in a stereo transmits a stereo to the whole pair of amplifier also known as microphone in the receiver.

The DSP can be found in devices like the smart phones, studio audio gear, headphones as well as smart speakers.

Ways DSP Signal Can Improve The Audio Signal

  1. Through The AEC Method.

The AEC method for short is the Acoustic Echo Cancellation. The function of the acoustic echo cancellation method is to prevent echo. In the absence of echo cancellation, your voice tends to be amplified to a distant end.

How DSP Originated

Many years back, am engineer in Memphis, Tennessee had vocals recorded for his songs. He had difficulty with the tape recorder. The issue with the tape recorder was that it had only two tracks to record on to. The band if singers had one if it while. It became very difficult for him to get the voice to sound natural.

When he was finally able to get that done, he came to the conclusion that the voice requires some echo. The first method he tried was to put the vocalist in the next hall, but then he found out that this resulted to a continuing serious effect.

Then, he tried putting the vocalist back into an enclosed compartment and positioning the speaker into the hall, and this resulted to a microphone feedback from the vocalist amplifier.

He then took another step of positioning a different microphone at the center of the hall so as to select the reverberant vocal that responds to its mixing console. The microphone in the hall was shifted around so as to change the nature of the echo.

He concluded it by finalizing the control over the amount of continuing serious effect he would make use of in his mixing. This called for the creation of the sound processing, that will further provide the advancement of Digital Signal Processing.

Forms Of Digital Signal Processing

Sound processing was divided into two types during the period of analogue recording studios. They are;

  • The Time-Based Processing.
  • Dynamic Processing.
  1. The Time-Based Processing.

The time-based processing has to do with changing the timing of particular elements in the audio signal, processing it with the use of an influencing path.

One of the most popular plugins used by the producers of music is the reverb.

The reverb enables one to send a lot of signals to a particular plugin, thereby saving the stress of having to joinmany plugins in the process of placing minimal strain on the Central Processing Unit of the computer.

Forms Of Time Based Processing

1. Chorus.

This form of time based processing is mostly used to give the audio source a solid feel. The choruses forms their effect by adjusting the source audio and holding the signal high. That is depending on the amplitude and the timing by making use of a different minimal density. The choruses can also be used to promote strings instrument.

2. Delay.

The delay processes whatever action has been downloaded into it. The delay was formerly known as a well known vocal effect being that it solidifies thelightness and thickness of the voice. The uniqueness of the digital signal processing is that you can input procedures that has not been put in place in the past to the ancient or analogue producers.

In a situation where it is being prolonged, the plugin can be connected to the speed of the track. Then can it be changed to stand for different musical values as regarding the speed.

  1. Dynamic Processing.

The dynamic processing signal can be changed by getting it through the digital signal processing. The plugin alters different parts of the signal’s dynamics as it passes through.

Forms Of Dynamic Processing


This is one of the most used digital signal processor. The frequently used feature of the equalization is the High Pass Filter. The high pass filter minimizes the lower density ranging from 75hz to the lowest, giving room for maximum density to go through.

The current equalizer gives different types of controls, making you to select the same densities you would prefer to boost.


The compressor is a programmed volume control that aids in minimizing the amplitude of the signal if it reaches the maximum level and allows it to perform in the absence of any disturbance when it is not above a particular level. The manner in which the compressor minimizes the level of the compressor by changing the ratio that tells the rate at which the amount of the signal is minimized.

You can also change the rate at which the compression begins as well as the clearness it will imply on the signal.

The outcome of it is that it will settle better on the mix as it stabilizes from minimum to maximum and it goes back and forth again.  Another outcome of it is that it alters the lightness or thickness of the audio signal, thereby providing it with more recognition in matters relating to the set level.

The disaster of making use of maximum inputs begins the moment there is an unplanned spike.

4. Limiters

The limiters contribute greatly to the modern music production. The limiters are similar to the compressors but they function more faster, and they are used to gear up the sensed level of the signal in the absence of switching a maximum unstable sound source.
