Steps to reproduce

Error in convolverNode implementation. For example when one set convolver buffers of size 128 samples with a Dirac (1 and 127 zeros). If you apply a Source Buffer composed of a dirac (1 and zeros), one expects to have for ouput 1 + zeros (or almost zeros). In practise it is not the case you have one + 64 zeros and after 64 values oscillating between 1/128 and -1/128. 128 is the size of the convolver filters. I have only observe this behaviour on Edge, not on firefox or chrome. This issue has a strong impact on audio quality.
