Where do the output partials actually land?

Prints the strongest partials of a synthetic speaker before and after processing, as multiples of the STFT bin grid. It is the quickest way to see the two synthesis modes described in spectral.rs:

accent off, the legacy channel-vocoder path. Each harmonic smears into a cluster of neighbouring grid frequencies (187.5 and 234.4 Hz around one partial), which is what makes it sound metallic.
accent on, an exact harmonic series at the canonical register (140.6 Hz and its multiples), whatever pitch went in.

Run with cargo run -p veilvoice-core --example diag_spectrum.

In plain words

A small program that runs the engine over a recording and prints what changed about its frequencies.

It is here so that the claims about what VeilVoice does to a voice can be checked by anybody, rather than taken on trust from a paragraph of prose.

WHAT THIS FILE CONTAINS

107 lines defining 3 functions (0 public), 0 types and 0 constants. Everything below is read out of the source, so it cannot disagree with the code.

WHAT CALLS WHAT

The functions this file defines, and the calls between them. An edge means the callee's name appears, called, inside the caller's body. This is a syntactic reading, not a type-resolved one.

This site loads no third-party script, so it cannot run Mermaid; the diagram above is the same nodes and edges drawn by the generator instead. GitHub renders the source below directly.
