this is my code
i think it<s not that much good but if it can do it’s work is ok

import wave
import numpy as np
def applyITDILD(sigMono, fs, ITD, ILD):

   sigMono = mono file
   fs=48000;
   ITD = int(input("put the ITD="));
# sigMono: Mono signal
# fs: Sample rate
# ITD: ITD in micro second
# ILD: ILD in dB

   numSampleITD = np.round(48000 * ITD * 1e-6)

   if numSampleITD > 0:
       sigStereo[:, 0] = sigMono.copy()  # Left channel of stereo
       sigStereo[:, 1] = np.hstack((np.zeros(numSampleITD), sigMono.copy()[:-numSampleITD]))  # Right channel of stereo
   else:
       sigStereo[:, 0] = np.hstack((np.zeros(numSampleITD), sigMono.copy()[:-numSampleITD]))  # Left channel of stereo
       sigStereo[:, 1] = sigMono.copy()  # Right channel of stereo

   return sigStereo;

ILD=gainL;
ILD=gainR;
# Determine gainL and gainR based on ILD [dB]
gainL=int(input('gainL='));
gainR=int(input('gainR='));
sigStereo[:, 0] = sigStereo[:, 0] * gainL;
sigStereo[:, 1] = sigStereo[:, 1] * gainR;

return sigStereo:

with wave.open("ITDILD0.wavfile") as wav_file:
    print(wav_file)

itd is delay time to get th stereo
ild is gain make up to localize the sound

i want it to run and output the sound result
when run it it has problem with sigStereo
