Free Prompt Transformer: Convert Any Prompt to 6 Nyquist Bands

Free Prompt Transformer: Convert Any Prompt to 6 Nyquist Bands By Mario Alexandre March 21, 2026 sinc-LLM Prompt Engineering What the Transformer Does The sinc-LLM Prompt Transformer is a free online tool that takes any raw prompt and decomposes it into 6 specification bands following the Nyquist-Shannon sampling theorem. It identifies missing bands, suggests content for them, and outputs a structured prompt that is 97% more token-efficient. x(t) = Σ x(nT) · sinc((t - nT) / T) The tool is available at tokencalc.pro and is completely free to use. No account required. How It Works The transformer follows a three-step process: Step 1: Band Detection Analyzes your raw prompt to identify which of the 6 specification bands are already present: PERSONA, CONTEXT, DATA, CONSTRAINTS, FORMAT, TASK. Step 2: Gap Analysis Identifies missing bands and estimates the aliasing risk for each. CONSTRAINTS (42.7% quality weight) and FORMAT (26.3%) are flagged as high-priority if missing. Step 3: Structured
