摘要
This paper develops an output-driven resampling formulation for fine pitch adjustment of recorded signals. A fractional input-position increment combines the desired frequency ratio with independently specified input and output sample rates. Each output sample is evaluated from neighboring input samples, and gradual rate changes preserve the current input position. Musical interval mapping and direct sine synthesis are treated as distinct layers. The formulation separates tuning resolution, numerical accuracy, interpolation quality, and streaming correctness. Optional rational-factor representations use freely chosen approximation parameters; numerical illustrations do not define constants required by the algorithm. Linear interpolation provides a low-cost evaluation kernel but does not establish a universal signal-quality or frequency-accuracy guarantee.
