SoundSense class

Captures microphone amplitude using AudioRecorder from the record package and emits a normalized RMS level (0.0–1.0).

To use, call SoundSense.microphone (factory) and add it to NerveController:

NerveRoot(
  controller: NerveController(
    sound: await SoundSense.microphone(),
  ),
  child: MyApp(),
)

Alternatively, inject any Stream<double> with SoundSense.withStream.

Constructors

SoundSense()
Creates a SoundSense that emits 0.0 constantly (silent stub).
SoundSense.withStream(Stream<double> rawStream)
Creates a SoundSense backed by a custom stream of RMS levels (0.0–1.0).
