Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency.

Digital signal processing and analog signal processing are subfields of signal processing. DSP applications include audio and speech processing, sonar, radar and other sensor array processing, spectral density estimation, statistical signal processing, digital image processing, signal processing for telecommunications, control systems, biomedical engineering, seismology, among others.

Discover the realm of digital signal processing and audio buffer manipulation. Learn the basics of the JUCE DSP module and how you can incorporate its classes in your own audio application and plugins. Add distortion through waveshaping and convolutionAdd grit to a synthesiser sound by creating harmonic distortion through waveshaping. Learn the basics of convolution to retrieve the sonic characteristics contained in an impulse response. Create a string model with delay linesImplement a realistic string model by means of physical modelling. Incorporate a delay line to create intricate echo patterns in the stereo sound field. Optimisation using the SIMDRegister classTake advantage of the processor's parallelism to perform single instruction multiple data calculations. Optimise your audio applications without introducing concurrency. The fast Fourier transformLearn how to display incoming audio data as a spectrogram by using the FFT class of the DSP module. Understand the benefits of using a Fast Fourier Transform. Visualise the frequencies of a signal in real timeLearn how to display incoming audio data as a spectrum analyser by using the FFT class of the DSP module. Understand the benefits of using a windowing function.
