All Classes and Interfaces

Class	Description
AnalysisPipeline	Block-level DTMF detection engine shared by DtmfDecoder (batch) and DtmfDetector (push).
BlockSizer	Analysis-block sizing logic for the DTMF detection pipeline.
ChannelMode	How an incoming sample array should be interpreted as one or more audio channels for DTMF detection.
ConfidenceScorer	Confidence scoring for a candidate DTMF tone pair.
DtmfConfig	Immutable configuration for DTMF detection and generation.
DtmfConfig.Advanced	Fluent builder for DtmfConfig, exposing every knob and the wider [4000, 192000] sample-rate domain.
DtmfDecoder	Batch DTMF decoder: turn a buffer of PCM samples into a list of detected DtmfTone instances.
DtmfDetector	Push-based DTMF detector: the caller feeds chunks of audio samples and receives DtmfTone emissions via a registered Consumer callback.
DtmfGenerator	DTMF tone generation: turn a key sequence into normalised double PCM samples suitable for feeding back through DtmfDecoder.decode(double[], DtmfConfig) or playing through an audio output.
DtmfStream	Pull-based DTMF iteration: expose a DtmfDetector as an Iterator over emitted DtmfTone values.
DtmfStream.SampleSource	A source of double PCM samples for DtmfStream.fromSource(SampleSource, DtmfConfig).
DtmfTone	Immutable value object describing one detected or generated DTMF tone.
FrequencyBins	ITU-T Q.23 DTMF frequency tables.
SampleConverter	Sample-format normalization for the DTMF detection pipeline.
TwistEvaluator	Twist computation and tolerance check for a candidate DTMF tone pair.
WindowFunction	Window function applied to each analysis block before the Goertzel bank computes magnitudes.
