Package com.tino1b2be.dtmf

package com.tino1b2be.dtmf

DTMF detection, generation, and streaming API for DTMF-Decoder v2.

This package hosts the public surface of the dtmf-core module: DtmfDecoder (batch), DtmfDetector (push), DtmfStream (pull), DtmfGenerator, together with the immutable value types DtmfTone and DtmfConfig and the ChannelMode / WindowFunction enums. Implementation details live under com.tino1b2be.dtmf.internal and are not part of the published API.

The module depends on com.tino1b2be.goertzel and only on com.tino1b2be.goertzel at runtime (Requirement 1.5). The concrete types are introduced starting at Stage 3 of the dtmf-v2-foundation spec; this package-info.java is present from Stage 1 so the source tree exists for the build-shape smoke tests in Task 1.9.

Class	Description
ChannelMode	How an incoming sample array should be interpreted as one or more audio channels for DTMF detection.
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.
WindowFunction	Window function applied to each analysis block before the Goertzel bank computes magnitudes.
