anged for the Helium version (state and coefs). Read the corresponding documentations.</li>
<li>Initialization of float biquad DF1 has changed for the Helium version (two init functions are required). Read the corresponding documentations.</li>
<li>The states of the vectorized filters are different from their scalar versions (which may break some algorithms which are working on the state of a filter like Goertzel)</li>
<li>For performance reasons, some vectorized algorithms may read one vector after the end
