> FFT-кадр из AudioSampleRef.

# GetFFTFrame

## Pins

| Direction | Handle     | Type           |
| --------- | ---------- | -------------- |
| in exec   | `exec-in`  | exec           |
| in data   | `sample`   | AudioSampleRef |
| out exec  | `exec-out` | exec           |
| out data  | `frame`    | FftFrameRef    |

## Runtime

На exec: `resolveInput(sample)` → `host.captureFftFrame(nodeId, sampleRef)` через spectral analyser bridge.

## Preconditions

* `AudioSampleRef.valid` и совпадение с активным stream/sample window

## Typical chain

```text theme={null}
get-sample.sample → get-fft-frame.sample
get-fft-frame.frame → collect-fft-frames (или trends pipeline)
```

## Code

`block-executor.ts` → `get-fft-frame`
