5/// Clone a [`SamplesBuffer`] into two independent buffers.
6///
7/// `rodio::SamplesBuffer` owns its backing Vec; this helper extracts the data
8/// and builds two new buffers with identical content.
9///
10/// # Example
11/// ```rust
12/// use rodio::buffer::SamplesBuffer;
13/// use proteus_lib::audio::samples::clone_samples_buffer;
14///
15/// let buffer = SamplesBuffer::new(2, 48_000, vec![0.0f32; 4]);
16/// let (a, b) = clone_samples_buffer(buffer);
17/// assert_eq!(a.count(), b.count());
18/// ```

22    let vector_samples = buffered.clone().into_iter().collect::<Vec<f32>>();
