Proud owner of a Quad Cortex I was wondering about the Impulse Response Length. While the built-in cabs do sound great I tried to use the Bogren Digital packs and saw that at 1024 samples the tail end of the Response is cut off. I know it’s not that of an issue but I was wondering with such a powerful machine it could be a little longer to represent accurately the files.
It is well known that to capture only the effect of the speaker and cab, without any room effects, you only need about 20ms impulse response. Typically anything greater would start to capture room effects. Hence the use of 1024-pt IRs. since 1024 samples @48Khz is 21.33ms.
‘‘well known’’ does not apply to us, mere mortals
