TG,

I believe the first thing to try is to create a new (empty) document and File>Place the file (in question) in it.

There may be certain losses (hopefully acceptable, if any).

The next step(s), to try to recover more, may require some more effort.

Before the more serious work, you may try opening by DoubleClicking the file with Illy closed.

To be continued:

Here are two Adobe instruction pages describing file recovery:

TG,

To continue, the two Adobe pages describe specific cases, but you may use them as inspiration.

The key is that often the first part of the file is corrupted, blocking the remaining sound part, so basically you may cretae an empty sound file, skip the first part of the corrupted file place the remaining part of the code in it.

There may still be things missing, and there may be strangenesses, but once you have an open file, you may copy the contents into a new file in the normal way.

Hopefully, further cross posting can be avoided.

TG,

As you can see on the pages mentioned in post #3, you can open the AI files as text files, and then you can see and compare the lines of code building each file.

The first part of each file is the wrapping defining the structure, folllowed by the part defining the artwork. Some of the artwork part may be corrupted, but more likely the structure part at the beginning is (it may be as little part snipped off at the very start).

So you can copy (at least some of) the part of code defining the artwork from the corrupted file and insert into the sound file after the initial part.

You may compare the two files and try to work out which part to move and where, using the file parts shown on those Adobe pages as guides.

I hope this was not too woolly.
