Capturing binaural room impulse responses for high-quality auralization purposes requires a signal-to-noise ratio of >90 dB which is unattainable with MLS-measurements due to loudspeaker non-linearity but fairly easy to reach with Sweeps due to the possibility of completely rejecting harmonic distortion.
