**Header:** `ClikaRT/processor/processor.h`

Per-call overrides for [`AudioProcessor::process`](./AudioProcessor.md#process). Only the knobs the pipeline reads fresh each call are here; nothing that would invalidate the processor's precomputed window / DFT / mel-filterbank tensors or its output-shape contract (sampling rate, FFT/window geometry, mel-bank geometry, feature type). A set field replaces the loaded config's value for THAT call only. [`norm_mean`](./AudioProcessOptions.md#norm_mean)/[`norm_std`](./AudioProcessOptions.md#norm_std) are scalar operands (element `[0]` is read); both fields OWN their values.
