LivRec/BR-80 wave files

I uploaded the files to box.com May be  you can diagnose them?

I notice Box.com has issues with rock1 but will preview and play rock2.

I downloaded both files and had a look. "rock1 E.WAV" is definitely not a WAV file. In fact, it's not even an audio file of any kind. It is mostly filled with zeroes except for 3,728 bytes of unrecognized data that repeats every 64KB. That means almost 95% of the file is zero-filled, so it isn't an audio file of any kind. There's no way it could make any recognizable sound in any player. I don't know what you were listening to in Classic Media player but it wasn't this file.

If you're certain that this is the file your BR-80 produced in Live Rec mode then I think you should contact Roland tech support. Your BR-80 may be defective. The only other explanation I can think of is that the memory card might not be compatible with your BR-80. But if that's the case, I'd expect to see some error messages when you record.

I suppose it's also possible that your PC has a virus that changed the file after you copied it from the BR. But then I'd expect the second file to be infected as well. Or maybe something failed in the copying process. Hmmm... now that I think about it more, that seems like the most likely explanation. It would explain the repeating block of data every 64KB since the Windows file copy code probably copies data in 64KB chunks.

If it happens again, try playing the WAV file directly from the memory card in VLC. If that works but it won't play the copy on your hard drive, then the copy is corrupt. Also, after you copy a file from the BR to your PC, compare the file size of the copy to the original file on the BR. If they are not exactly the same, then the copy is corrupt (ie; the problem is with your computer, not the BR).

Easy enough to re-do!

Well, crap. I can't duplicate it.

And I just realized what the difference may have been. The batteries were real low. I seem to recall one bar.  I'd say BR80 was about to tell me to replace them. I replaced the batteries AFTER the messed up recording.With the freshly charged Nimh batteries, I can not duplicate the screwed up file. I CAN make some nastily distorted recordings with the levels way too hot!!

I think it was "Helter Skelter" where Lennon plugged his guitar into the mixer and overdrove the tube mixer for that famous "nasty" tone he had on that tune.

It had to be with the low batteries, the BR couldn't render the overdriven file.

If I think of it, I'll try again when my batteries are low again.

Yes, near-dead batteries could definitely cause corrupt files. That's probably what it was. You should never try to record with batteries that are near-dead. Not only will you get errors, but it could corrupt your memory card if the power drops to critical levels while writing to the card. Then you won't be able to get any of your songs off the card.

I recommend using the AC adapter whenever possible, especially for critical operations such as updating the firmware, backing up, or copying files to the PC. When you must use batteries, make sure they're fully charged.
