    Hi


    I want to know How REW(Room Equalization Wizard) works.can you please share the block diagram of how the received(Log Sweep) audio processed and converted to IR(Impulse Respose).this is only for my educational curiosity.

    See Swen Müller, Paulo Massarani, "Transfer Function Measurement Using Sweeps", JAES Volume 49 Issue 6 pp. 443-471, June 2001. An extended version of the paper is available at CiteSeerX.

    Hi

    I have read the document it is showing many of the measurement method(as below)
    and its comparison.which one of these REW uses

    1)Time Delay Spectrometry

    2)Dual Channel FFT Analysis

    3)Stepped Sine

    4)Maximum length sequences (MLS)

    5)Periodic Signals of length 2^N

    6)Non periodic sweeps

    Non periodic sweeps? or Stepped Sine?

    Stepped sine isn't a sweep. Log sweep is an example of a non-periodic sweep.
