The DSP technology, also known as Digital Sound Processing is a digital signal processing system to make them more manipulable. When you buy your digital dictaphone, the fact that he embarks the DSP feature can be very advantageous to you. Indeed, thanks to this, you can easily record quality soundsBecause surrounding noises will be removed when playing. But in practical terms, what is this technology?

DSP or Digital Sound Processing technology

The DSP technology or Digital Sound Processing defines itself as the process of processing a digital signal to analyze, measure and manipulate it. This action is done using a set of mathematical calculations and algorithms. The processing of the digital signal involves an exchange of information so that it can be transformed and observed. This is a fast-paced procedure, so much so that the user does not have time to notice it.

To explain it more simply, during the recording phase, analog audio is received by your dictaphone. This signal is then converted into a digital signal by an analog-digital converter and transmitted to the DSP. The latter performs theENcoding MP3 and saves the file in the memory of your digital dictaphone. During the playback phase, the file is extracted from the memory, decoded by the DSP, and then converted into an analog signal via the digital-analog converter so that it can be transmitted via the speaker system.

The information of a DSP can be used by a computer to control elements such as security, the phone, home theater systems and video compression. Signals can be compressed so that they can be transmitted quickly and more efficiently from one place to another. It can also improve their quality or provide information that is not detected by human ears.
