Could you build this?
No Implementing a high-performance scientific computing and digital signal processing (DSP) library in Java requires deep mathematical domain expertise in numerical analysis, algorithm design, and low-level performance optimization.
What it would actually take: The project requires implementing complex algorithms (Radix-2/4/Split FFTs, Welch's method for PSD, Butterworth/Chebyshev filter synthesis, STFT) in pure Java while managing garbage collection overhead and memory layout for Android. Doing this accurately requires rigorous mathematical validation against SciPy/FFTW and deep expertise in numerical stability and vectorized floating-point operations (such as Java Vector API).

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
