Struct AudioPipelineBuilder 

pub struct AudioPipelineBuilder { /* private fields */ }

Available on crate feature audio only.

Builder for constructing audio pipelines.

Example

let handle = AudioPipelineBuilder::new()
    .tts(my_tts)
    .stt(my_stt)
    .vad(my_vad)
    .agent(my_agent)
    .build_voice_agent()?;

Implementations

impl AudioPipelineBuilder

pub fn new() -> AudioPipelineBuilder

Create a new builder with default settings.

pub fn tts(self, tts: Arc<dyn TtsProvider>) -> AudioPipelineBuilder

Set the TTS provider.

pub fn stt(self, stt: Arc<dyn SttProvider>) -> AudioPipelineBuilder

Set the STT provider.

pub fn music(self, music: Arc<dyn MusicProvider>) -> AudioPipelineBuilder

Set the music generation provider.

pub fn vad(self, vad: Arc<dyn VadProcessor>) -> AudioPipelineBuilder

Set the VAD processor.

pub fn pre_fx(self, fx: FxChain) -> AudioPipelineBuilder

Set the pre-processing FX chain (applied before STT/VAD).

pub fn post_fx(self, fx: FxChain) -> AudioPipelineBuilder

Set the post-processing FX chain (applied after TTS).

pub fn agent(self, agent: Arc<dyn Agent>) -> AudioPipelineBuilder

Set the agent for voice agent pipelines.

pub fn buffer_size(self, size: usize) -> AudioPipelineBuilder

Set the channel buffer size (default: 32).

pub fn build_tts(self) -> Result<PipelineHandle, AudioError>

Build a TTS-only pipeline (Text → TTS → Audio).

pub fn build_stt(self) -> Result<PipelineHandle, AudioError>

Build an STT-only pipeline (Audio → STT → Transcript).

pub fn build_voice_agent(self) -> Result<PipelineHandle, AudioError>

Build a voice agent pipeline (Audio → VAD → STT → Agent → TTS → Audio).

Requires tts, stt, vad, and agent to be set.

When the desktop-audio feature is enabled and both capture and playback are configured, the caller should use the returned PipelineHandle to wire the capture stream into input_tx and route output_rx audio frames to playback. Starting capture requires a device ID and a CaptureConfig (with the desktop-audio feature), and playback requires a device ID, so the builder stores the instances and the caller completes the wiring at runtime.

pub fn build_transform(self) -> Result<PipelineHandle, AudioError>

Build a transform-only pipeline (Audio → FxChain → Audio).

pub fn build_music(self) -> Result<PipelineHandle, AudioError>

Build a music generation pipeline (Text → MusicProvider → Audio).

Trait Implementations

impl Default for AudioPipelineBuilder

fn default() -> AudioPipelineBuilder

Returns the “default value” for a type.
