Import/open broken wav file?

Post by MFS » Sat Aug 09, 2014 5:11 pm

I have a flawed wav file that I can't import. (Running Audacity 2.0.5 under Win 7)

The wav is a recording from an Edirol R-09HR, recorded at 24/48. Something went wrong with the unit and it shut itself down, but I have about 7 minutes of data which would be useful to me.

I don't know know anything about internal file structures, but possibly there's something wrong with the header or suchlike? The data that's there seems fine -- I can listen to the track on Foobar, but I can't do anything to open it in Audacity.

Regular Open and Import > Audio just open a blank stereo track. I've tried various combinations under Import > Raw Data, but I just get white noise. "Channels" and "Sample rate" seem reasonable enough -- 2 and 48000, but I don't actually know what I should be picking under "Encoding" or "Byte order".

I don't know if it throws any light on the problem, but I tried as a workaround to see if I could downsample the file to 16/44.1 with r8brain, and it wouldn't open the file, telling me the file is "formed incorrectly and thus cannot be read". Also: this happened to me once before and I sent a similarly crashed-out file to a friend with Cubase. He had no trouble opening/re-exporting it for me.

Thoughts? Anything I can do to get this data into audacity?

Thanks!

Update: on a whim, I tried the "quick convert" in Foobar. It gave this warning: "Malformed or truncated chunk found at 36 bytes, claimed length 0 bytes, truncated to 123207636 bytes"

But it did create a FLAC that opened in Audacity. So at least I have a workaround.

Try Encoding = Signed 24 bit PCM.
