+     * Reverb for instance) will either receive control of the effect engine or not, depending
+     * on the priority parameter. If priority is higher than the priority used by the current
+     * effect engine owner, the control will be transfered to the new application. Otherwise
+     * control will remain to the previous application. In this case, the new application will be
+     * notified of changes in effect engine state or control ownership by the effect callback.
+     * After creating the AudioEffect, the application must call the initCheck() method and
+     * check the creation status before trying to control the effect engine (see initCheck()).
+     * If the effect is to be applied to an AudioTrack or MediaPlayer only the application

+//      Effect control interface
+/////////////////////////////////////////////////
+
+// The effect control interface is exposed by each effect engine implementation. It consists of
+// a set of functions controlling the configuration, activation and process of the engine.
+// The functions are grouped in a structure of type effect_interface_s:
+//    struct effect_interface_s {
+//        effect_process_t process;
+//        effect_command_t command;
+//    };
+
+
+// effect_interface_t: Effect control interface handle.
+// The effect_interface_t serves two purposes regarding the implementation of the effect engine:
+// - 1 it is the address of a pointer to an effect_interface_s structure where the functions
+// of the effect control API for a particular effect are located.
+// - 2 it is the address of the context of a particular effect instance.
+// A typical implementation in the effect library would define a structure as follows:
+// struct effect_module_s {
+//        const struct effect_interface_s *itfe;
+//        effect_config_t config;
+//        effect_context_t context;
+// }
+// The implementation of EffectCreate() function would then allocate a structure of this
+// type and return its address as effect_interface_t
+typedef struct effect_interface_s **effect_interface_t;

+For gain, the LFO generates a value that modulates in terms

+linear gain = 10^x, where x = LFO value in dB / 20.

+  10^x = 2^(log2(10^x)) = 2^(x * log2(10))

+so we need to multiply by log2(10) which is just a constant.

+2^x, but it actually assumes that the input is in cents, and within
+the 2^x approximation converts its input from cents to octaves
+by dividing its input by 1200.
+
+So, in order to convert the LFO gain value in dB to something
+that our existing 2^x approximation can use, multiply the LFO gain
+by log2(10) * 1200 / 20
+
+The divide by 20 helps convert dB to linear gain, and we might

+* Quantization of pitch and codebook gains.                                *
+* MA prediction is performed on the innovation energy (in dB with mean     *
+* removed).                                                                *
+* An initial predicted gain, g_0, is first determined and the correction   *
+* factor     alpha = gain / g_0    is quantized.                           *
+* The pitch gain and the correction factor are vector quantized and the    *
+* mean-squared weighted error criterion is used in the quantizer search.   *

+    //cluster early (relative to other tracks), or the last frame

+    //The problem is that we need a way to mark as stream as

+    //We need to give pCurr some value that means "you've reached EOS".
