Struct FileNode 

pub struct FileNode { /* private fields */ }

A node that reads and decodes audio from a file.

It uses the symphonia library to support various audio formats. Like MicrophoneNode, it handles sample rate conversion automatically.

Example

use rust_audio_api::nodes::{FileNode, NodeType};
use rust_audio_api::AudioContext;

let mut ctx = AudioContext::new().unwrap();
let sample_rate = ctx.sample_rate();

let dest_id = ctx.build_graph(|builder| {
    let file = FileNode::new("music.mp3", sample_rate).unwrap();
    builder.add_node(NodeType::File(file))
});

Implementations

impl FileNode

pub fn new(file_path: &str, target_sample_rate: u32) -> Result<Self, Error>

Creates a new FileNode for the specified file path.

Parameters

• file_path: Path to the audio file.
• target_sample_rate: Processing sample rate.

pub fn set_gain(&mut self, gain: f32)

Sets the output gain for the file playback.

pub fn process(&mut self, _input: Option<&AudioUnit>, output: &mut AudioUnit)

Trait Implementations

impl Drop for FileNode

fn drop(&mut self)

Executes the destructor for this type.
