Reconstruction of Audio from Absolute Spectrogram

Hello,
I have the absolute of a audio signals' spectrogram.
I lost the phase data because of various processing applied on the original spectrogram of the signal.

I'm trying to reconstruct the signal in a meaningful (Audibly) manner.
The obvious inverse won't work (The DFT inverse of the absolute, Since the Phase is significant).

Anyone has experience with the problem?
Could anyone refer me to a code, article, etc...

Thanks.
