Struct AudioEngine 

pub struct AudioEngine {
    pub volume: f32,
    pub buffer: Vec<i16>,
    pub midi_events: Vec<MidiNoteEvent>,
    pub module_name: String,
    pub note_count: usize,
    pub sample_rate: u32,
    pub channels: u16,
}

AudioEngine holds the generated interleaved stereo buffer and provides simple utilities to mix/merge buffers and export WAV files.

Notes:

• Buffer is interleaved stereo (L,R,L,R…).
• Methods are synchronous and operate on in-memory buffers.

Fields

volume: f32

Master volume multiplier (not automatically applied by helpers).

buffer: Vec<i16>

Interleaved i16 PCM buffer.

midi_events: Vec<MidiNoteEvent>

Collected MIDI note events for export (non-audio representation).

module_name: String

Logical module name used for error traces/diagnostics.

note_count: usize

Simple diagnostic counter for inserted notes.

sample_rate: u32

Sample rate (can be overridden per-engine)

channels: u16

Number of channels (interleaved). Defaults to 2.

Trait Implementations

impl Clone for AudioEngine

fn clone(&self) -> AudioEngine

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AudioEngine

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AudioEngine

fn eq(&self, other: &AudioEngine) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
