Changes the sound frequency factor.
bool SetFrequencyFactor(float Factor, M32 * pDeviceResponse = NULL, void * pReserved = NULL);
true if the device received the command, false otherwise.
SetFrequencyFactor allows to change the frequency factor. A value =1.0 makes the sound is read a the original speed. A value >1 accelerates the sound, whereas a value <1 reduce the read speed.
