What Does DSP Stand For?

The term DSP has a couple of common meanings depending on the industry in which it is being used. The term DSP is most often used in the technology and digital marketing industries.

Digital Signal Processing/Digital Signal Processor

DSP can stand for digital signal processor, which technology functions that digitizes and manipulates real-world signals. These include voice, video, audio, pressure, temperature, and position. DSP can convert audio signals from hardware like microphones into a digital format from its analog signal or analog form. 

This transmission is built into many user interfaces, such as those on smart speakers, headphones, vehicle entertainment systems, smartphones, and more. DSPs have a range of functions and capabilities. An analog-to-digital converter and digital-to-analog converter (ADC and DAC) can be found in things like a Bluetooth chip, which uses DSPs to receive, process, and output audio, for example.

DSP architectures can quickly process many types of signals for various functions that an automated machine needs to perform. DSPs matter greatly in many of our favorite technologies!  

Demand-Side Platform

In digital advertising and digital media, DSP stands for demand-side platform. This interface system allows for ad buying and ad exchanges in real-time through one singular interface. Users gain access to the ad inventory that a marketing team posts, and then the media buyer can use this in their ad space. DSP interacts with things called supply-side platforms (SSP).
