Audio Convolution output is longer than input, how can i get around this when feeding data back to a stream of fixed length?

QUESTION

Audio Convolution output is longer than input, how can i get around this when feeding data back to a stream of fixed length?

Asked 2020-Oct-15 at 12:18

After taking audio data from a stream of length x, the data is then convolved with an impulse response of length 256. This gives the output vector a length of (x + 256 - 1). When the data is then fed back into a stream of length x there are 255 samples of overshoot that then causes popping and clicking.

Is there a work around for this? Im not 100% on how to merge the larger than original buffer into the output again without losing random samples or causing this issue.

I left out the larger irrelevent parts of the code, it all works its just this issue i need fixed. Its just here to give an insight into the problem.

You remember the 255 extra samples and add their values to the 255 samples at the beginning of the next output block.
