"Maximum file size of 2.0 GB exceeded."

Hi! I imported an "aifc" file into Logic, which is 171.3 MB and lasts 2h.

 

I put some compressor and limiter on the audio channel with the file and cut the beginning and the end of a file a bit.

 

I then tried to bounce the whole "project" into an mp3 to which Logic responded with: "Maximum file size of 2.0 GB exceeded."

 

When I bounced only half of my song, the result size was something of 80 MB.

 

I noticed that when I exported this half of the song, the warning before bouncing was that the bounce requires around 1.0 GB of disk space, as if it would not recognize that I only checked the mp3 bounce and not the PCM.

 

What is happening here?

Thank you.

Thank you.

But there are two more questions which arise from this solution, which gave me a 1.9 GB caf file.

 

1.) Why does Logic create enormously big files from much smaller input?

 

2.) How do I convert this 1.9 GB caf file to a regular size mp3?

1. Probably because the AIFC was of a smaller bitdepth and a lower samplefrequency than the format you chose to bounce to. Plus it is a compressed format, that is the "C" in AIFC.

2. I'm not sure you can, MP3's may have a limited file size or play duration too. However, you can simply try by bouncing an MP3 just as you have bounced the .caf. Logic will probably tell you if the piece is too long for MP3, and if not, then not...

1. What is funny with the "mp3" option is that it tells me it exceeds the 2GB limit, but if I split it in half and make two mp3s they are both much much smaller - together they take about the size of the imported "aifc" file or even less.

So there must be a way to export just an mp3 without splitting it, right?

 

2. I would be surprised if there wasn't any way in a complex audio software like Logic to just import one large (but compressed) audio file, cut it a bit, equalize it a bit, and then bounce/export it with a similar size. Otherwise, please suggest me some other software to make these quick edits to large (but compressed) audio files.

I'm sorry, but this is a matter of you needing to know what you are actually working with. One large piece over 2 GB, two halves together under 2 GB? You obviously missed something here.

What bitrate did you use for MP3? What is the bitdepth and samplefrequency of the original AIFC? What is the compression or encoding method?

 

Your point 2 is invalid, as AIFC is not a recommended format to work with in any DAW, as isn't MP3, as isn't any form of encoded compressed audio. AIFF, WAV, BWF, CAF or SDII are the formats of choice for use within a DAW, they are all socalled PCM formats.

Compressed audio (MP3 etc) is and end format (where you bounce to), not a format that is wise to use inside Logic.

Logic is not at fault here.

If you want to convert it back to AIFC you can either try Compressor which is part of Logic Studio, or track down and download Soundconvertor or Soundhack. Or iTunes, which has a rich formatchoice as well.

Thank you Eriksimon for your kind explanations.

So let me get this straight, if .aifc or .mp3 file is imported into Logic it somehow expands/decompresses and becomes much larger in size?

Yes. Just like an inflatable doll which uses little space in storage or transport but becomes larger in size if you intend to use it properly.

Haha, ok, I get it.

 

So what would you do if you would have a 2h long .aifc which you must edit and send to your friends?

Is this the best way - exporting it to .caf after editing it in Logic and then compressing it again?

Or would you do something else? Would you even edit it in Logic?

You CAN use them UNINFLATED.

But you'll get a decidedly DIFFERENT EXPERIENCE.

(OR SO I'VE HEARD! :shock:)

Don't send the AIFC, bounce to MP3 or AAC - AAC can be the smallest, it can 'handle' the most compression, but it is less universal than MP3.

You'll still end up (if it is stereo) with a 120 MB mp3, or a 80 MB AAC. Anything smaller would sound deteriorated.

 

I would bouce to .CAF and mail a CD.

But if sending a CD was not an option, how would you edit a very long AIFC, which can only be bounced in CAF in Logic, and send it in compressed format back to friends?

Sorry for bugging you, but I would really like to do this...

 

Let me repeat my problem.

 

I have an AIFC file, which I have to cut a bit and equalize a bit.

It's 2 hours long.

This means that when it "decompresses" in Logic after I import it, it is too long to export it in any format but CAF.

 

Now I have this CAF file which sound the way I want it to sound, but I cannot find any way to convert it back to MP3 or AAC (or AIFC).

 

Thanks again and sorry for my noob questions.

I would not do it in AIFC. It is outdated, and not widely used. In my 18 years of Mac audio editing, I have hardly ever used it. I would return an MP3. I'd use AAC, if I knew everybody can play that back. Or you can upload it to Soundcloud or similar music sharing sites. Or a file sharing service, etc.

Let me repeat my problem.

 

No.

 

I cannot find any way to convert it back to MP3 or AAC.

 

Stop trying to find and start looking.

 

The answer is earlier in this thread, craftely hidden in plain sight, in more than a thousand words, too.

And by solving this riddle, you'll complete your quest on this dung... forum.

I think you found a workaround but for others having this issue and stumbling onto this thread the solution is very simple. When you go to bounce change the PCM format to CAF and select MP3 and the resolution you want the MP3. You can discard the CAF later.

OMG - this kills me. I have a premiere on saturday and we have to bounce out the eight 7hrs tracks - which seems impossible.

PLEASE! PLEASE! is there anything to do that? it seems that over a certain size the files explofe - like even in 128kbs they would be enourmeous!?

PLEASE!

I'm not sure of what the limit is of CAF. I was able to bounce 2+ hours by changing AIFF default to CAF and adding my mp3 output.

 

David, the problem is the inability of Logic (and APPLE OS) to bounce an AIFF to a file size bigger than x (2GB maybe?) Changing AIFF to CAF removes this limitation, but may still have a file size limitation of it's own.

It's all in the manual:

http://documentation.apple.com/en/logicpro/usermanual/index.html#chapter=14%26section=9%26tasks=true

 

There is a maximum recording size according to file type, as follows:

 

AIFF: The AIFF file format cannot handle audio file recordings larger than 2 GB:

For 16-bit, 44.1 kHz stereo files, this equals a recording time of about 3 hours and 15 minutes.

For 24-bit, 96 kHz, 5.1 surround files, this equals a recording time of about 20 minutes.

 

 

WAVE (BWF): The WAVE file format cannot handle audio file recordings larger than 4 GB:

 

For 16-bit, 44.1 kHz stereo files, this equals a recording time of about 6 hours and 30 minutes.

For 24-bit, 96 kHz, 5.1 surround files, this equals a recording time of about 40 minutes.

 

CAF: If the size of your recording exceeds the above limits, choose the CAF (Apple Core Audio Format) file format, which can handle the following recording times:

 

About 13 hours and 30 minutes at 44.1 kHz

 

About 6 hours at 96 kHz

 

About 3 hours at 192 kHz

 

The bit depth and channel format—mono, stereo, or surround—do not affect the maximum recording size of CAF files.

I'm using version 9.1.6 and having this problem. my file is 1:46:30 long. I bounce large files like this all the time (podcasts) however, this time i'm getting the "maximum file size of 2.0 GB exceeded" regardless of type of file i attempt to bounce to. i have tried bouncing to all available file types, and get the warning every time, even though the file is under 2 hours (which i thought was whole issue with file types anyway). is this a bug? any advice? i usually just bounce to MP3 which works fine, even with longer files.

i'm running into this error myself with podcasts now. last night i recorded a ~2:20:00 file in caf format

 

when i tried to bounce the file, i still got the file size error

 

looking inside the logic project, every file included is caf

 

as it stands now, i am having to bounce half my project at a time and reassemble them in audacity. an extra 40 mins using a freeware program!

 

it's becoming very frustrating
