Struct BufferLatencyDto 

pub struct BufferLatencyDto {
    pub input_buffer_latency_ms: f64,
    pub output_buffer_latency_ms: f64,
    pub total_buffer_latency_ms: f64,
}

I/O buffer latency for the current audio configuration.

Buffer latency is the delay imposed by the hardware frame buffers: the driver accumulates a full block of samples before delivering them to (or accepting them from) the application. The formula is:

latency_ms = (buffer_frames / sample_rate_hz) × 1000

When [cpal::BufferSize::Default] is in use the actual frame count is unknown at runtime; a conservative fallback of 256 frames is substituted so the UI can always display a practical estimate.

Fields

input_buffer_latency_ms: f64

Input-side buffering delay in milliseconds.

Time the ADC driver holds samples in its internal buffer before delivering them to the application ring buffer.

output_buffer_latency_ms: f64

Output-side buffering delay in milliseconds.

Time the application must fill the DAC driver buffer before the first sample is actually played.

total_buffer_latency_ms: f64

Total I/O buffer delay: input_buffer_latency_ms + output_buffer_latency_ms.

This is the minimum hardware-buffer component of the full round-trip latency.

Implementations

impl BufferLatencyDto

pub fn new(input_buffer_latency_ms: f64, output_buffer_latency_ms: f64) -> Self

Creates a new BufferLatencyDto, computing total_buffer_latency_ms automatically.

Arguments

• input_buffer_latency_ms — Input buffering delay in ms.
• output_buffer_latency_ms — Output buffering delay in ms.
