How to record over 2GB in Traktor Pro?

Hey everyone.

Last night I recorded a 4 hour + set in Traktor and noticed that after some amount of time (approximately 3 hours and 18 minutes into the set) the recording timer reset to 0. After my set I noticed that Traktor created two WAV files for the recording. I looked in the preferences for Traktor and they are set to automatically split file sizes greater than 2,048 MB. That is the maximum choice.

How do I record sets that are larger than 2 GB? I do not want split files as I want to create a podcast out of this recording and do not know how to make it one continuous mix (like I recorded it) now that there are two files.

Can anyone please help?

Thanks,
Keith

Unfortunately you probably cannot. And it's not Traktors fault... the WAV format itself has a file limitation size of 2GB.

Do they give you any other format choices?

Argh!

Hmmm I'm not in front of my computer at the moment to check. I'm pretty sure there were no other options but maybe someone else can chime in?

So does that mean my 4+ hour set (that is in two WAV files) cannot be made into one seamless set? I'm a n00b when it comes to audio-editing. Can anyone help with that?

Cheers,
Keith

You should be able to put the two back together in an audio editor, then export the final podcast in a different file format (AIFF, MP3, etc.).

Any recommendations on a free Mac program that does that Ryan?

Also, what's another way to combat this problem going forward? Let's say I want to record a 4 hour mix (not live in a club) and I want to break up my mixing by recording the set in two 2 hour stints. How can I record these two 2 hour files together? Would it be like mixing two 2 hour "songs" in Traktor? My only concern is let's say the first file starts at 130 BPM and ends around 136 BPM... How does Traktor know what BPM that file is when I go to sync it up with the second 2 hour file?

Thanks,
Keith

You can do that in Audacity no problem.

You probably wouldn't want to use "sync" to do this... the two files (provided Traktor is smart and buffers a bit when writing them out) should just line up, or they might stick a touch of overlap in there.

In audacity it should be really easy to line them up.

Even my little Samson Zoom H2 recorder does this, it'll split long sets into multiple 2GB WAV's.

Cheers Ryan, I'll try Audacity tonight.

What did you mean by not using Sync in Traktor? Do you mean just use my ear to line up the two files? As n00bish as this sounds, I'm not very good/sure at how to "nudge" two songs that are off in Traktor... Any idea how to do that? I just got the X1 so I'm sure there's some button on there to do this, right?

What are you trying to do? Like just record the first 2 hours at one time, then later on record another 2 hours, then join them?

That could be a little tough. You could just note down when at the last track of the first section the exactly BPM you were playing at. Then when you start recording the second half, just play that same track at the same speed and go from there.

Then aligning the two in audacity should be cake.

Yup that's exactly what I was getting at.

As far as Traktor is concerned (for it's sync function to work properly) I have to fill in the BPM tag so it knows that speed it's playing at, correct? So I'm saying if Section 1 starts at 130 BPM and ends at 136 for example two hours later, do I start Section 2 at 136 BPM right? Will Traktor be able to recognize that Section 1 was 130 - 136 BPM? Do I just manually edit the BPM tag to 136 when I want to mix it in? And do I hit "record" in Traktor with 1 minute left on Section 1 so that it records a bit of Section 1 and all of Section 2?

LOL... so much work to record and damn set! WTF!?!?

The BPM "tag" in the files indicated the speed at 0 pitch. I don't think Traktor even uses this at all... it uses the information in its own tags for the beatgridding to sync tracks up.

What you really need to write down is the last track you played, and at what pitch you were playing it. When you start the second half of your set, play the same track at the same pitch and just continue.

Cheers Ryan.

PS. How are the CDJ2000s? Happy with them?

Yep, they are great

i've stitched together such traktor recordings in audacity. you shouldn't worry about it too much. just put the second recording behind the first one. zero overlap, zero gap. no speed correction necessary. export as mp3 and you should be fine

sweet, i'll download audacity tonight and give it a crack. bummer about the WAV limitation thing. Traktor should be able to export as MP3. i can't be the only dj that's ever encountered this, lol.

it's because a software that can encode mp3 usually has to pay licensing fees to the fraunhofer institute. at least when it's sold commercially.

what is this info about wavs cannot be bigger than 2GB? is that a fact or bullshit? thats 3 hours of music. i have 6 hour sets of mp3. could u record as mp3 maybe?

i'm confused about this too.

there's two limitations here. one is the 2gig file size limit on fat32 partitions (which is believed to be 4gb sometimes), and the other is a limitation within the wave file header, that only reserves 32bits for the file length - which practically equals to 4gb. (see http://de.wikipedia.org/wiki/RIFF_WAVE for that)

the first limitation does not apply to macox native partitions (consider however: when saving to an external hard drive you haven't formatted yourself, you might be dealing with fat32 anyway) nor ntfs partitions when working with windows.

i have successfully saved & loaded wave files bigger than 2gb in audacity, but i haven't breached the 4gb limit yet. all other programs i tried refused to save more than 3h22min (= 2gb) on a macbook pro. this might be due to internal integer handling, where you lose one bit when you don't mark your variables unsigned. one bit loss leads to the effective file size limit being cut in half.

then this crappy wav format must die. oh well, two hours is the perfect lenght for anything though.

FWIW, I recorded almost 6 hours of audio via Audacity the other night.

i think raw should have no limitations except for the ones inherited from the file system. but it lacks a header, so you will need to know what sampling frequency, bit rate, channel# and byte order your files are in.

There's also AIFF.

can i record my mixes in traktor using audacity, instead of traktor's internal recorder? if so, how do i set that up?

I think all you have to do is select the Mac's main output as the recording source... I can't remember if it allows you to do this by default or not. You may have to use Soundflower or some utility to do it. I'm sure someone else will chime in, it's been a while since I have done that.

I actually record output from a mixer so I don't have to worry about it anymore. I can't look right now because I'm at work...sorry!

Another cool recording app is Wiretap:

BTW, can Ableton do this copy/paste splicing job as well?
