Call this on every sample in processBlock. Returns a bipolar [-1, 1] signal.

    // Get the unipolar [0, 1] value from the pre-calculated wavetable
    const float unipolarOutput = wavetable.getUnchecked(phase * (wavetable.getNumPoints() - 1));

    // Advance the phase using the externally calculated delta
    phase += phaseDelta;

    if (phase >= 1.0f)
        phase -= 1.0f;

// Call this from your processor before each block to set the LFO speed.
// The processor is responsible for calculating the correct delta for Hz or BPM sync.
