Struct AudioBuffer 

pub struct AudioBuffer { /* private fields */ }

Normalized, interleaved f32 audio with sample-rate and channel metadata.

Samples are stored interleaved (frame-major) and scaled to the [-1.0, 1.0] range regardless of the source bit depth. The buffer is cheap to clone and owns its samples, which can be taken with AudioBuffer::into_samples.

Implementations

impl AudioBuffer

pub fn new( sample_rate: u32, channels: u16, samples: Vec<f32>, ) -> Result<Self, ResampleError>

Create a buffer from interleaved f32 samples.

Returns ResampleError::InvalidSampleRate when sample_rate is zero, ResampleError::InvalidChannelCount when channels is zero, and ResampleError::BufferError when the sample count is not a whole number of frames.

pub fn sample_rate(&self) -> u32

Source sample rate in Hz.

pub fn channels(&self) -> u16

Number of channels.

pub fn samples(&self) -> &[f32]

Interleaved sample slice.

pub fn into_samples(self) -> Vec<f32>

Consume the buffer and return the owned interleaved samples.

pub fn frame_count(&self) -> usize

Number of frames (samples.len() / channels).

pub fn is_empty(&self) -> bool

true when the buffer holds no samples.

pub fn resample_to(&self, output_rate: u32) -> Result<Self, ResampleError>

Resample to output_rate, preserving the channel layout.
