Struct RecorderState 

pub struct RecorderState {
    pub started_at: Mutex<Option<Instant>>,
    pub sample_rate: u32,
    pub max_samples: usize,
    pub format: Mutex<RecordFormat>,
    /* private fields */
}

Handle shared between audio callback and UI thread.

• Callback: buffer.lock() and pushes f32 interleaved samples.
• UI: calls stop() to swap out the buffer and spawn encoder.

Fields

started_at: Mutex<Option<Instant>>

sample_rate: u32

max_samples: usize

format: Mutex<RecordFormat>

Which container to write when the user stops recording. Defaults to FLAC; toggled by the f key in the TUI.

Implementations

impl RecorderState

pub fn new(sample_rate: u32) -> Arc<Self>

pub fn is_recording(&self) -> bool

pub fn elapsed_seconds(&self) -> f32

pub fn start(&self)

pub fn push_frame(&self, l: f32, r: f32)

Called from the audio callback for every output frame.

pub fn stop_and_encode(&self, dir: &Path) -> Result<PathBuf>

Stop capture and spawn the encoder thread. Returns target path.

pub fn toggle_format(&self) -> RecordFormat

pub fn current_format(&self) -> RecordFormat
