I have a really strange problem with an audio recording from my Tascam DR-60DMKII linear PCM audio recorder.
I recorded about 40 minutes of audio using DUAL ST mode, where two audio streams are recorded at once: one at 0db and one at -6db.
When I was getting ready to stop the recording, the plug came out of the device, which powered it off while still recording (thus not finalizing). When I turned the device back on, the new recording didn't appear on the device.
I ran a recovery program and found the RAW PCM file that was being written. I imported it into Adobe Audition using the
File > Import > Raw Data... mechanism, and that seemed to succeed.
The problem I'm having is that when I play the file, I hear the 0db recording and the -6db recording on the same channel, so it essentially sounds like an echo. Oddly enough, I pulled a totally different recording from the device that did complete successfully, and that one exhibits the exact same "echo" problem.
I believe these are supposed to be PolyWave-type files, so it seems like there's just some interleaving that needs to be de-interleaved, but I can't figure out how to do it and my Google skills are failing in this area.
Anyone know anything about this type of problem? (I'm not an audio professional by any means, so forgive my lack of proper terminology.)
