Re: [sc-users] Index.ar vs BufRd.ar

Yes, I think BufRd offers interpolation, looping, and multichannel output.

They should be the same under the correct settings.

It does not interpolate between values (which is maybe why you were getting different results) and it doesn’t loop the buffer. It is designed for just reading values out of a buffer, but not “playing” the buffer as audio. BufRd, on the other hand, seems to be designed for audio, with interpolation and looping.
