Module audio 

Audio graph engine for oveRTOS.

Provides safe wrappers around the C graph API: build a DAG of audio nodes (sources, processors, sinks), validate formats, and execute in topological order.

Structs

AudioBuf

Audio buffer descriptor (borrowed from the C layer).

AudioFmt

Audio format descriptor.

Graph

Owned audio graph session.

StaticProcessor

A static wrapper for an AudioProcessor that provides safe &'static mut access for graph_add_processor.

Enums

SampleFmt

Audio sample format.

Traits

AudioProcessor

Trait for implementing custom audio processing nodes.

Functions

device_cfg_i2s

Build an ove_audio_device_cfg for I2S transport.

graph_add_node

Add a node to the graph. Returns the node index.

graph_add_processor

Register a custom processor node on the graph.

graph_build

Validate formats, resolve execution order, allocate buffers.

graph_connect

Connect two nodes. from feeds into to.

graph_deinit

Tear down the graph and release all resources.

graph_init

Initialize the audio graph.

graph_process

Process one cycle (app-driven mode).

graph_start

Start the graph (sink-driven mode).

graph_stop

Stop the graph.
