Struct AudioCaptureVTable 

pub struct AudioCaptureVTable {
    pub open: fn(sample_rate: u32, channels: u16) -> u64,
    pub read: fn(handle: u64, out: &mut Vec<f32>) -> u32,
    pub close: fn(handle: u64),
}

A platform audio-capture backend (microphone), registered by the dll so MicrophoneWidget can pull real samples instead of the test tone. Like CaptureVTable but yields interleaved f32 audio rather than RGBA video.

Fields

open: fn(sample_rate: u32, channels: u16) -> u64

Open the default mic at sample_rate x channels. Opaque handle, or 0 on failure.

read: fn(handle: u64, out: &mut Vec<f32>) -> u32

Block for the next chunk, writing interleaved f32 into out (resized). Returns the frame count (out.len() / channels), or 0 on error / EOF (the worker then stops + closes).

close: fn(handle: u64)

Close + free the source.
