with the idea that certain functions in flac apodization are signal alteration types of functions surrounding the use of specifically the headphones and its behaviour especially during acoustics in songs or sounds, the main point also to make that a certain large or medium amount of functions actually keep to the point of making the signal also up to the tax of higher grade dynamic range whereas the lpc and residual coding are involved. also the quantization has more along the measure of many functions being within the moment of having more specific role in algorithmic terms whereas more apodization allow complexity to enter the signal in respect of dynamic range and accurateness. the main point to make about freac is that with experience in listening and experimentation with different setting up of the windows is that i myself found some way where i can get around in some respect to actually how flac is supposed to work. the aiming around putting the signal up to something along the line of flowing the way of values where there is no certain clarity is not how flac actually behaves. there is a certain step wise idea and a certain rudiment idea and no other way to make out the flac format sort of makes it up to actually its proper use. so with experimentation i can get around in encoding with flac and also there is no really documentation about the format in some respect unless someone in the largest ideal actually simply experiments with signals to go about using it the way it works out in the manner its allotted a simple of more complex functioning. in stereo music you have high estimation of the apozation where the lpc values have context with the stereo signal. if  you use low lpc values that would only be for non stereo conversion where the signal is sort of not really music. so insomuch the detail of using many amounts of apodization of functions and use of the lpc values the main point is in my experimentation i have some clarity in playing my role in time over my using the conversion steps to get what i suppose i can idealize in to make out the right and proper use of the converting steps.
