parallel master daw and tape
I had a live recording of a Johnny Cash tribute Band to mix and master. And for mastering I tried to use an Tascam 103 Casette Tape.
It was funny, but a lil too much, so I tried to make it parallel and to sync it with the original mix. But that didn’t worked.

I placed a 1-sample-long piece of audio in front, to have a good visualization to sync the tracks.
I played back the mix, send it to tape and immediately back into PT again so that the tape won’t have 2 different speeds while recording and than playing back afterwards. It was just 1 run. So I thought the deal would be only the technical latency and the time from the recording head to the playback head.

But I could not sync the tracks in pro tools. Every Time I was on point, I got a weird scratching of high frequencies. It was no chorus and no phasing like you get, when you come close to sync. To describe it, I think more of a Lesley effect in the upper frequencies….

is there anyone who tried something similar?

Am I doing something wrong?

Is my tape vary the speed just a lil bit so fast, that I can’t hear it in solo mode, but when I listen to mix and tape in parallel?

Cheers and Greetings

Re: parallel master daw and tape
There will ALWAYS be some sort of chorusing effect. Wether you hear it as that or something else, what you’re describing is pretty much that.

You’re trying to sync a digital file with a source running through a machine that relies on a motor spinning a head. If you were running it through hardware like a comp or EQ, no prob. But not a machine that has a physical motor spinning.

Essentially, it’s just wow and flutter. Better machines have better specs in this regard, but they ALL will have it. Turntables, reel to reel, cassette etc.

If you want to avoid that, and you probably should, use a plugin simulation and make sure to disable any wow and flutter settings.

Re: parallel master daw and tape
yeah, i total see your point.
I saw that technique in a vid. I found it again:


I thought, if you do it in 1 run, it could be possible. And since it was working in that vid, and in my case it wasn't, I thought, there could be a mistake somewhere...

With plugins its easy. sure. but still not the same, and for that project I was in mood to try something special :)

now I will give the clients two masters. one with plugins only and one recorded to tape and back and finished in the daw.

Lets see...

Thanks for your help

Re: parallel master daw and tape
I wouldn't belive much of what's on YouTube, most times is just a guy trying mind-blowing techniques that 99% of the time are completely unnecessary

(Ps. yes, I know [emoji16])

Re: parallel master daw and tape
Analog tape can do nice things to a mix, BUT, expecting "good" from any cassette tape is not a great idea(cassette tape sound quality is generally bad). If you really want what tape does, buy a good tape emulation plugin(it will do a much better job and you won't have to deal with tape hiss, wow/flutter or the poor frequency of cassette). Just because you CAN do something, doesn't mean you SHOULD:o
