frequency response is only up to 15khz when the sampling rate is 96khz

[gladys0313]

Hello! I found an issue when checking the output RIR. In MCRoomSimOption.m, I set the sampling rate as 96khz, but when I checked the resulting RIR, its uppermost frequency in the spectrum is only about 15khz. At the same time, I found that this issue might be due to the far distance between the source and the receiver.

I tried to solve this issue by setting the parameter MinImgSrc and MinRayEngy to very low levels, -150 and -200, respectively, but the uppermost frequency in the response doesnt change. Do you recommend any solution to this issue? I was wondering whether you could update the addSource function with an overall gain paramter for all kinds of directivities, so that the source energy can be larger.

Thanks.
