Revert Bounced Track Back to Logic Project?

Long story short, I accidentally deleted my most recent backup of a project, and I only have a bounced .m4a track of a previous backup. I want to go back in and edit a lot of what's in the track. Is there any way to sort of unbounce the track so that it's not a single .m4a file, but it's a .logicx project again, with separate tracks and regions and whatnot?

Nope, its impossible. You cannot take out the eggs, baking soda and flour in an already baked loaf of bread.

FYI: You said you deleted a back-up, so you still have the original project. So just go in there and get your tracks. A back-up is a 2nd copy, so you have the 1st copy. right?

Unfortunately, no. I thought I made a copy of my most recent version and then deleted the copy once I backed it up to a cloud storage, but I actually didn't make a copy and I deleted the original files I had on my computer before I realized. And now for some reason the file I updated to the cloud is corrupted and won't download (currently contacting customer service about that...).

Sign up for an online backup service like Backblaze. It's worth $5 a month to be able to go back to previous versions (up to a certain time limit of course.)

We have all done it and we have all learned form it. Next time always check your back-ups to see if they work and always have 3 copies of every project and have one kept off site in case of fire or theft.

FYI: If you just deleted it form your PC like you said and did nothing else, then its in your TRASH BIN. Go in there and restore it.

No, you cannot 'unbounce' the m4a. It is just a recording of the stereo signal that you sent to the speakers that afternoon.

There do exist audio-separation programs that will extract sounds by category. ADX STEMS will separate out Vocal, Drums and Everything Else. Izotope RX 7 will give you those 3, plus bass. But you must understand these are separations, not your original tracks 'back'. When recombined at unity gain, the separations will add back up to the original stereo file, but in pure isolation they are usually artifact-laden and kind of weird.

I have used these programs to do things like lower the acoustic guitar bleed in a singer/songwriter's vocal mic. If I needed to get rid of the acoustic guitar altogether, the vocal stem all by itself would sound very weird. Little bits of it would be missing and little bits of the guitar would sneak through. It's not really like getting your tracks "back".

You might be able to get the "bass" but you could never get back the DI bass vs the miked amp bass. You could get "drums" but not the overheads vs the snare close mic.

As for things like regions and clips, plug-in settings, automation and so on - no way. That information was never put into the bounce in the first place. You can't even transfer that data from one brand of DAW to the other - even when you do have the session file.

If I were you, I would chalk it up to experience and re-record the song. Consider the first one "practice", and maybe you can make the re-do even better than the original.

Since you are using a Mac you might also want to look into Disk Drill. It will allow you to recover files that you have already erased. The longer its been since you erased em the harder they are to recover.
