To keep the levels constant, you have done everything you can think of. You tried to repair the amplifier and placed the speakers in strategic positions. However, you still could not reduce the eco. You can hear background noise and comments. To combat these problems of sound quality, there is a simple solution: the DSP.
We are looking at some of the fundamentals of digital signal processing.
What is the DSP?
Digital signal processors (DSPs) take real-world signals such as audio, video, voice, temperature, position, or pressure, which are digitized, and then maneuver them accurately. It is designed to perform mathematical functions such as subtract, add, divide and multiply very quickly.
How they work
Signals from real world sources are converted by digital signal processing into digital data which can then be analyzed. The signals will generally be in analog form. The study is done in digital form, because when we reduce a signal in numbers, its mechanism can be manipulated in more detail than when it comes from real-world sources.
Digital data can be converted to an analog signal with improved quality when the DSP has completed its work. A DSP can intensify the frequencies, sort the sound of a signal and retain others.
Types of audio signal processors
The signal processors may be simple or multifunctional, digital or analog, or incorporated into other components in an audio system. Most were unconnected devices, but became multifunctional over time with digital signal processors integrating a wide range of functions at a fraction of the cost of individual processors.
The troubleshooting functions in the current DSPs are volume and volume control, equalization, filters, compressors, dynamics processor, expanders and noise barriers, limiters, self-timer, corrector automatic door mixers, automatic microphone mixers and return reducers.
Although you can find it everywhere, it is an extremely refined chip technology. DSP chips are used in fax machines, sound cards, modems, high-capacity hard drives, cell phones, and digital TVs. In 65% of the world’s digital cell phones, DSPs are used as the engine. This number will only increase as the number of wireless applications increases. Digital signal processing is used in many fields, including music processing, sonar, biomedicine, radar, speech and seismology, communications and imaging.
What DSP can do
You need to consider some of the most common noise issues you face when determining whether the DSP can help your audio system. DSP tools can solve many problems if the acoustics of the room are relatively good. If you have a poor sound quality using a graphic equalizer, a DSP tool, you can rectify the problem. Likewise, DSP tools such as Expander, Delay, Compressor, and Auto Mixer can solve problems such as unwanted noise, frequency response problems, a loud sound source, and feedback, respectively.
What DSP can not do
Adding DSPs to your system is not an alternative for later rules of conventional sound support. For example, audio processing will not prevent echo. The DSP has no effect once the sound energy is released by the speaker. The problem will only get worse if you increase the level of the audio system.
