The thread you linked to said: Long story short, i just copied the header from the other file and then fixed it up for the new file size. Have you tried this?. Also, can't you play it with VLC or ffplay?.

here is the correct file that was edited out/saved from the undeleted file.

What's wrong with it? Windows media player plays it, but it's only a few seconds long. How should it be? [FMC Studios] - [Caries Field] - [Ctris] - [Pman] - [Chess for allegroites] |

okay, let's start it from the beginning. i'd need to recover a large voice recording the recording itself has been lost or deleted, a big file of 218 MBytes has been undeleted/recovered but the problem is that it is corrupt, the beginning of could you check the attached file and check if it is if so, could you help me and explain how i could create

According to Gspot [1] the header is probably missing or corrupt. If i understand correctly your problem, you have this big file which actually is a container for wav files, correct? References[FMC Studios] - [Caries Field] - [Ctris] - [Pman] - [Chess for allegroites] |

i have done it already. i have 2 small files that i could cut from end of the big file. both of them are small few-second recordings and are not important. the rest is a large recording which misses the beginning. i'd need to make a correct header for this big file. how can i do it?

You can try taking just the header for the small recordings, put that into a new file, and take the rest of the large file where you notice the sound actually starts, and slap that to the end of the header file you created just before, then modify the length in the header to match the data you added. It might take a little bit of work, but I'm sure you can figure it out. -- |

"You can try taking just the header for the small recordings, put that into a new file, and take the rest of the large file where you notice the sound actually starts,..." i don't know if the corrupt file starts properly. "...and slap that to the end of the header file you created just before, then modify the length in the header to match the data you added. It might take a little bit of work, but I'm sure you can figure it out." also, i do not know how to modify the length. for this i should know where i find the info about the length of the recording.

I think the audio sample you posted has a corrupt header, what you could do (and what i did) is get a new sample from your recorder, just record something short for a test and post that. [FMC Studios] - [Caries Field] - [Ctris] - [Pman] - [Chess for allegroites] |
