The scores for anchor signals with 3.5-kHz LPF are omitted in the figure for a clear display.
In the MUSHRA test, each listener compared the sixteen reference signals (host audio signal) with eight differently processed test audio clips for each reference signal: hidden reference (no modification), data-embedded audio signals processed through five different configurations, and two anchor signals obtained by low-pass filtering (LPF) with 3.5 and 7.0 kHz cutoffs [28].
These minimal targeting and anchor signals allow localization of luciferase on the outer side of the plasma membrane.
After verifying the specificity characteristics, the scaffoldin was then expressed and anchored to the cell wall of L. plantarum using three different lengths of anchor signals, cwa1, cwa2 and cwa3 [ 41].
By analyzing the ESTs generated, we could predict transmembrane regions, glycosylphosphatidylinositol (GPI) anchor signals, signal peptides, and amino acid repeats, and this helped in identifying proteins that could be useful in developing disease control strategies.

Energy compensation is used for the anchor signal to ensure that the energies of anchor signal and original signal are equal.
The channel signals of anchor are the same signal derived from the downmix signal, which can ensure that the virtual sound reproduced with anchor signal will always stay in the middle of active loudspeakers.
Thus, the basic audio qualities of anchor signal and original signal are the same, but the spatial information of them are totally different.
To remove such potential biases, we calculated the MUSHRA differential scores by subtracting the scores for the unprocessed signal (hidden anchor signal) from all the other scores.
Since the virtual sound of original signal may be located in arbitrary location among loudspeakers, the spatial quality of anchor signal is severely degraded compared with the original signal.
Although the 3.5-kHz anchor signal was poor in sound quality test, some subjects indicated its virtual source position was not so bad in the movement than the discrete virtual source.
