Hmmm… quite a pity that the .ptf file format is some kind of binary gibberish. But from a company that requires you to buy a certain brand of soundcard in order to use their software, I wouldn’t expect anything less…
I have a bunch of sessions that I recorded in a studio in another country last month. Luckily most are continuous takes, so the .wav files are useful on their own. But a few of the multichannel takes, I didn’t record all the channels, so the numbering of the soundfiles doesn’t match up for all the tracks.
I actually took a photo of the screen during that session, to help me remember which files belonged with which other files! Besides that, I guess the only other option is to match them up by length/timestamp of the individual files.
I simply can’t imagine what I would do in a more complex situation with punch-in/punch-outs, etc. Throw down 1K for a Digidesign soundcard just to open the sessions? No f-ing way!
