-    Interpolator for resampling a stream of floats using 4-point lagrange interpolation.
-
-    Note that the resampler is stateful, so when there's a break in the continuity
-    of the input stream you're feeding it, you should call reset() before feeding
-    it any new data. And like with any other stateful filter, if you're resampling
-    multiple channels, make sure each one uses its own LagrangeInterpolator
-    object.

-    It can be configured to do 2 times, 4 times, 8 times or 16 times oversampling

+    This class can be configured to do a factor of 2, 4, 8 or 16 times
+    oversampling, using multiple stages, with polyphase allpass IIR filters or FIR
+    filters, and latency compensation.
 
     The principle of oversampling is to increase the sample rate of a given
-    non-linear process, to prevent it from creating aliasing. Oversampling works
-    by upsampling N times the input signal, processing the upsampled signal
-    with the increased internal sample rate, and downsampling the result to get
-    back the original processing sample rate.
-
-    Choose between FIR or IIR filtering depending on your needs in term of
-    latency and phase distortion. With FIR filters, the phase is linear but the
-    latency is maximised. With IIR filtering, the phase is compromised around the
+    non-linear process to prevent it from creating aliasing. Oversampling works
+    by upsampling the input signal N times, processing the upsampled signal

+/** An IIR filter that can perform low, band and high-pass filtering on an audio
+    signal, with 12 dB of attenuation per octave, using a TPT structure, designed
+    for fast modulation (see Vadim Zavalishin's documentation about TPT
+    structures for more information). Its behaviour is based on the analog
+    state variable filter circuit.
+
+    Note: The bandpass here is not the one in the RBJ CookBook as its gain can be
+    higher than 0 dB. For the classic 0 dB bandpass, we need to multiply the
+    result by R2.
+
+    Note 2: Using this class prevents some loud audio artefacts commonly encountered when
+    changing the cutoff frequency using other filter simulation structures and IIR
+    filter classes. However, this class may still require additional smoothing for
+    cutoff frequency changes.
