The spectra are separated in space by 0.0071. The standard echelle reduction including subtraction of bias and scattered light, flat-field correction, wavelength calibration, and rectification of the 2D spectrograms was carried out us-ing standard routines of the MIDAS and IRAF echelle reduc-tion packages.

To examine the similarity of the reconstructed spectrograms from the neural responses to the spectrograms of the attended and unattended speakers, we measured the correlation coefficient (Pearson’s r) between the reconstructed spectrograms with both ODAN and the actual clean spectrograms of the two speakers. The correlation values were estimated over the entire duration of the M-T experiment. A new diffractive imaging technique called Imaging By Integrating Stitched Spectrograms (IBISS) is presented. Both the data collection and phase retrieval algorithm used in IBISS are direct...
