 The `ma_lpf`, `ma_hpf` and `ma_bpf` objects support a configurable number of poles, but if you only need a 1-pole filter you may want to consider using

 If an even number of poles are specified, a series of 2-pole filters will be processed in a chain. If an odd number of poles are specified, a series of 2-pole
