<p>Higher-order approximations covering any frequency band can be obtained using</p>
<pre><code>no.noise : fi.spectral_tilt(order,lowerBandLimit,Bandwidth,p)
</code></pre>
<p>where <code>p=-0.5</code> means filter rolloff <code>f^(-1/2)</code> which gives 1/f rolloff in the
power spectral density, and can be changed to other real values.</p>
<h4 id="example">Example</h4>
<p>// pink_noise_compare.dsp - compare three pinking filters</p>
<pre><code>process = pink_noises with {
f0 = 35; // Lower bandlimit in Hz
bw3 = 0.7 * ma.SR/2.0 - f0; // Bandwidth in Hz, 3rd order case
bw9 = 0.8 * ma.SR/2.0 - f0; // Bandwidth in Hz, 9th order case
pink_tilt_3 = fi.spectral_tilt(3,f0,bw3,-0.5);
pink_tilt_9 = fi.spectral_tilt(9,f0,bw9,-0.5);
pink_noises = 1-1' <:
no.pink_filter, // original designed by invfreqz in Octave
pink_tilt_3, // newer method using the same filter order
