 The details of the derivation can be found in our preprint **Differentiable All-pole Filters for Time-varying Audio Systems**[^1].
 We show that, given the instataneous gradient $\frac{\partial \mathcal{L}}{\partial y_t}$ where $\mathcal{L}$ is the loss function, the gradients of the LPC filter with respect to the input signal $x_t$ and the filter coefficients $A_{t, :}$ can be computed as follows:
