The DSP library bundles every digital-signal-processing component shipped with mne-cpp: FIR / IIR / cosine-tapered / Parks–McClellan filter design and application, FFT-based overlap-add convolution, polyphase rational resampling, Morlet wavelet and multitaper time-frequency representations, Welch and multitaper power spectral density estimators, surface Laplacian (CSD) and SPHARA spatial filters, ExtendedInfomax and PICARD ICA, Maxwell filtering (SSS, movement compensation, fine calibration), cHPI line-noise removal, bridged-electrode and LOF bad-channel detection, EOG regression and assorted real-time wrappers (averaging, covariance, noise PSD, inverse operator update).

DSPSHARED_EXPORT resolves to Q_DECL_EXPORT inside the DSP target itself and to Q_DECL_IMPORT for every downstream consumer; it collapses to an empty token in static builds. This macro must annotate every symbol that crosses the shared-library boundary on Windows so the import library is generated correctly.
