Digital Signal Processing (DSP) delay is a fundamental technique employed by audio engineers to manipulate the timing of audio signals in the digital domain. Delays introduce a temporal offset between the original and processed signals, enabling the creation of various effects, spatial enhancements, and artistic sound design. This repository provides a basic implementation of a DSP delay in C++. The purpose is to illustrate the core concepts of digital audio delay and how it can be integrated into audio processing workflows.
DSP delay involves introducing a time delay to an audio signal in the digital domain. This delay can be implemented as a simple time offset or as a more complex effect with feedback, modulation, and filtering. Audio engineers leverage DSP delays for a myriad of purposes, ranging from basic echo effects to sophisticated spatial enhancements.
The duration between the original sound and its delayed version. Short delay times create flanger or chorus effects, while longer delays contribute to echo and reverb.
The portion of the delayed signal that is fed back into the delay line. Feedback is crucial for creating sustain, decay, or infinite reverberation in delay-based effects.
Dynamically varying the delay time introduces shifting effects like chorus or flanger. Applying filters to the delayed signal can alter its frequency content.
Uses a short delay between two identical signals to create a perception of localization or spaciousness. Ideal for widening the stereo image without introducing noticeable echo.
