Capstone Project: Real-Time Audio Effects Processor

Set up a real-time audio input/output stream in a chosen programming environment.

Implement a windowed, overlapping buffer for processing real-time audio chunks.

Apply the FFT to buffered audio data to compute and visualize a real-time spectrogram.

Design a lowpass or bandpass filter (IIR or FIR) to meet a specific audio frequency cutoff specification.

Implement the designed filter on a real-time audio stream using its difference equation.

Design a bank of parallel bandpass filters to serve as a multi-band audio equalizer.

Implement a simple echo effect using a circular buffer for delayed signal feedback.

Develop a chorus or flanger effect by modulating the delay time of a delay line with a low-frequency oscillator.

Analyze the phase vocoder method for time-stretching and pitch-shifting.

Integrate spectral analysis, equalization, and a chosen audio effect into a single processing chain.
