Can I measure a speakers anechoic response in a normal room with just LAUD ?
Yes …and no. Prepare for the long answer!: You can use gating in LAUD (in its SINE, or MLS instruments) to get a frequency response measurement equivalent to an anechoic chamber down to a frequency of about 300Hz (it depends on how long of a delay can be arranged between the time a wave arrives directly from speaker to the microphone an when the first echo off a room wall, floor, or ceiling arrives at the microphone — the lowest anechoic response frequency will be about 1/(that delay time)). Gating basically measures the response of the first-arrival wave, and ignores all waves after the first reflection arrives at the microphone.
