  • 1b0cefb367 fix: GPU FreqShift float32 precision loss causing audio clicks Root cause: CUDA FreqShift kernel casts accumulated phase to float32 via sincosf((float)phase). After ~385k samples the phase reaches ~4M radians where float32 loses 0.03-0.1 rad precision, producing sin/cos errors up to 0.1 at frame boundaries → audible clicks. Fix: reduce phase to [-π,π) before float cast using phase = phase - rint(phase/2π)*2π (fast GPU intrinsic, no perf impact). Same fix applied to SSB product kernel. Additional fixes in this commit: - Go-side phase normalization (math.Remainder) after each frame update in both GPU and CPU extraction paths. Prevents float64 drift over hours of continuous operation. - Overlap trim: floor→ceil for non-divisible decimation factors. 512/20=25 (floor) trimmed only 500 of 512 overlap samples → 12 leaked. Now (512+19)/20=26 trims 520, cleanly removing all overlap. Affects NFM (decim=20); WFM (decim=8, 512%8=0) was already clean. - Click detector rewritten: second-derivative transient detector replaces first-derivative delta scanner. Old detector flagged hundreds of false positives per frame on normal FM audio. New detector computes |2b-a-c| (discrete acceleration) which is near-zero for smooth signals and large only for true impulse transients. Threshold 0.15. Files changed: native/exports.cu - phase reduction in freq_shift + ssb_product kernels kernels.cu - same (Linux CGO build) cmd/sdrd/helpers.go - phase normalize + ceil trim (GPU + CPU paths) recorder/streamer.go - transient detector + prevAudioL field Requires DLL rebuild: .\build-gpudemod-dll.ps1
