I do not think that datageist answer is the answer. By just saying that you can convolvolve simpler in the fourier domain, you do not explain why do you need the convolution in the first place. When you have impulse response, you need convolve to get the response. Pointing at Fourier domain does not explain you why you need to convolve. Might be he wanted to say that phylosophy is useless rambling?
In comments to his answer, https://dsp.stackexchange.com/a/9753/4701, datageist fails to defend his answer. Is it a feature of democratic society that truth is considered offensive and not acceptible? What is offensive in my message? IMO, it is offensive is opposite. When you ban the truth and call offensive things that are not offensive, this is what is offensive.
