Short for "digital signal processing", a DSP system manipulates audio signals to achieve a certain goal. Some DSP systems can work with video and other data as well. For example, a DSP system might include an algorithm that detects a primary audio source and isolates it from any unwanted noise, so that the signal is clearer.
Audio processing with channel filtering using DSP ...
https://ieeexplore.ieee.org/document/8301696
Audio processing with channel filtering using DSP techniques Abstract: In this paper, a novel surround sound system operated by DSP boards is developed. Besides woofer(s) and tweeter(s), the audio system has been improved by adding additional speakers for handling mid-frequencies by designing a particular band-pass filter to process its mid-range.

Audio and Digital Signal Processing (DSP) Machine Learning Section. Machine Learning with an Amazon like Recommendation Engine. Create a sine wave. In this project, we are going to create a sine wave, and save it as a wav file. But before that, some theory you should know. Frequency: The frequency is the number of times a sine wave repeats a second. I will …

Digital Signal Processing generally approaches the problem of voice recognition in two steps: feature extraction followed by feature matching. Each word in the incoming audio signal is isolated and then analyzed to identify the type of excitation and resonate frequencies.
What is a DSP?: All that power in a little chip - SoundGuys

If a device is processing audio, it's nearly guaranteed to have a built-in DSP. For example, there’s a DSP inside your smartphone to decode MP3 files, boost the bass of your music, run the math for active noise cancellation, and recognize your voice when you say “ Hey, Google! ”.

The DSP performs the MP3 encoding and saves the file to memory. 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.
Guitar Effects Processor Using DSP

Digital signal processing has been used in the audio field for some time. One of its uses is to modify specific audio signals to generate effects not inherent in the signal. The digital domain provides quicker and easier methods of audio processing, especially with increased speeds and decreased costs of microprocessors and digital signal processors.
