Spectral Lab 1.0.0
Spectral Lab 1.0.0 — GPU spectral freeze + morph
Capture frozen spectral layers from your input, stack them into a sustained cloud, and Morph / Smear / Jitter through it. Stacking many layers is the job that genuinely suits a GPU, so there's an opt-in GPU engine for it.
Honest about where the GPU helps
A few layers are faster on the CPU (the default). The GPU engine wins at big clouds — at 128 layers the CPU overruns the real-time budget (11,520 µs/hop) while the GPU does it in 1,946 µs (5.9×). The live status line shows the engine, layer count, measured µs/block, and a % of real-time headroom gauge derived from your own device.
Verified
GPU output matches a CPU reference bit-for-bit (xcorr = 1.0); the GPU's high-layer timing is impossible on the CPU; a sustained GPU load raises the machine's GPU-utilization counter well above idle.
