Seeking Solutions for Clipped Audio: De-Clipping Tools/Algorithms for Envelope and Phase Angle Extraction

Question

I’m working with two audio signals—one is a stimulus that the participant heard, and the other is the response the participant gave. The stimulus audio was recorded at a high gain/volume and subsequently clipped, while the response audio was not clipped and remains intact. I have both the original stimulus (before de-clipping) and the response recordings.

Current Challenges: The stimulus signal has been clipped during recording, which distorts the waveform and complicates the extraction of envelopes and phase angles. The response signal, on the other hand, is clean and unaffected by clipping, so no restoration is needed there. Request: I’m looking for recommendations on de-clipping tools or algorithms that could help repair the stimulus signal before performing envelope and phase angle extraction.

I just noticed that the stimulus signal is clipped due to high gain/volume during recording. I haven't tried any specific solutions yet, as I’m just starting to look for suggestions on how to de-clip the stimulus signal and repair the distortion. I’m hoping to find methods that will allow me to restore the clipped portions before performing envelope and phase angle extraction.
