Get accompaniment part in audio

Hi i thanks for your work it's amazing
I wonder if I can take accompaniment part in audio without generate accompaniment.wav
like this
{[
'start music' : 1 ,
'end music' : 2 ,
'name of audio ' : accompaniment.wav
] ,
[
'start music' : 3 ,
'end music' : 4 ,
'name of audio ' : accompaniment.wav
]
}

Thanks you for reading my issue
