for now i could get it working via having a fixed sized single array defined at start with headroom i modify in functions, but dynamic sizes create/delete would be nice,
this seems to be the feature for not too much pain will test.. find it a bit strange/hard in c++ to pass arrays from/to functions, the pointer stuff, ram ect arf..still learning

Two options, I think...
1) Dont use new:

2) Find a way to significantly reduce the # of times it's called, such as a one time allocation.

it's in a synth code ,in some part od the code it looks like each time a new buffer is created it adds to memory with no release, until reaching limits and crash.
i tried to use 'delete' operator both with [] or not , but it doesn't semm to do something
.a bit stucked from a while.. any ideas?the code is very wide but it seems this isolated part seemms to be the problem:
(to summup it's an up-scaling array function to process on lows sizes array in order trying to save some cpu then re-stretch.
CODE:
////// .....double* S1_HI = new double[SMP_DUR_LOW * reduxa]; ..... S1_HI = UPSCALE_16X(S1_LOW, SMP_DUR_LOW); // <---------- memory increase stops when bypassing ...... delete[] S1_HI;S1_HI = nullptr; // this calls those functions://////////////////////////////////////////////////////double* BEZIER_MULTI::UPSCALE_2X(double *Input,int sizein){int sizeOut = sizein * 2;double* TMP_OUT = new double[sizeOut];double valin;int j;for (int i = 0; i < sizein; i++){j = i * 2;valin = Input[i];TMP_OUT[j] = valin;if (i < (sizein-1 )){TMP_OUT[j + 1] = (valin + Input[i+1]) / 2;}else{TMP_OUT[j + 1] = valin +((valin - Input[i - 1]) / 2);}}return TMP_OUT;delete TMP_OUT;TMP_OUT = nullptr;}//////////////////////////////////////////////////////////////double* BEZIER_MULTI::UPSCALE_4X(double *Input, int sizein){int sizeOut = sizein * 4;double* TMPb_OUT = new double[sizeOut];TMPb_OUT = UPSCALE_2X(UPSCALE_2X(Input, sizein),sizein*2);return TMPb_OUT;delete TMPb_OUT;TMPb_OUT = nullptr;}/////////////////////////////////////////////////////////////////double* BEZIER_MULTI::UPSCALE_8X(double *Input, int sizein){int sizeOut = sizein * 8;double* TMPc_OUT = new double[sizeOut];TMPc_OUT = UPSCALE_4X(UPSCALE_2X(Input, sizein), sizein * 2);return TMPc_OUT;delete TMPc_OUT;TMPc_OUT = nullptr;}//////////////////////////////////////////////////////////////////double* BEZIER_MULTI::UPSCALE_16X(double *Input, int sizein){int sizeOut = sizein * 16;double* TMPd_OUT = new double[sizeOut];TMPd_OUT = UPSCALE_4X(UPSCALE_4X(Input, sizein), sizein * 4);return TMPd_OUT;delete TMPd_OUT;TMPd_OUT = nullptr;}////////////////////////////////////////////////////////Statistics: Posted by 23fx23 — 09 Jun 2015, 01:44
