Huge project file

Cubasis
1

Hi,

One of my Cubasis projects is huge : almost 20 GB !

I succeeded to reduce it to 9 GB clearing history, but it is still huge for what it is : a 3 audio tracks, 9 mins project.

Any idea ?

Other projects on the same format weight 200 to 400 MB for half the duration.

I would also like to know what is the size linked to ? Are audio clips embedded ? If yes, can the imported files (in “my audio files”) be deleted after inserting them into the project ?

Thanks in advance !

Have you Normalised any of the Wav files? if you have this will automatically double each file in size.

Does it double because it keeps the original data? Maybe mixing down samples and then using them avoids this?

Also using this.. would increase the size significantly (depending on the original rate)

Hi Mike,

Thanks for the advice, yes indeed. Strange that a simple gain doubles the audio file size.

Anyway, even unnormalized, that would be a roughly 4 GB project, still huge regarding files size (2 tracks are 32 bits mono files)

Have you tried clearing the projects undo history under Setup-Project?
Once done re-launch Cubasis and clear the Trash.

This is one way to get rid of the backup audio-files that are created when normalizing or processing individual audio-events that are part of larger files.

Currently when normalizing an event that is part of a bigger file the entire source-file is duplicated…

…Cubasis should just make a copy of the portion the audio event uses instead of duplicating the entire source file, but that is something @LSlowak and his team could take a look at.

All files are copied into the project when added so it’s safe to delete them from the media bay without affecting the project.

The file duplication is needed so Cubasis can ‘undo’ the processing.
(each audio-file / event has its own undo backup file).

Hopefully we’ll get non-destructive event based normalization (ie. event/clip gain) at some point which would make it possible to avoid the file-duplication.

Yh i figured that..

That’s why i thought mixing down (or freezing and then deleting the original track) should get rid of the excessive memory hog in the project.

Hi CJ,

The problem is when you go into wave editor and Normalise it, the wav file on the main screen also Normalises, so there is no way you can delete the original.

I understand that.. but if you put that wave into a project and mixdown it (especially in realtime) then it should be a new wave without any undo data from the previous wave :thinking: you can delete the previous wave from your mediabay then.

There are some wave apps (similar to goldwave back in the day) and it might be easier to normalize your waves there before building a project in Cubasis.

Thats a good point, for iPad users we can send all our wav files to a app called Audioshare and Normalise them one by one and then send them back into Cubasis, it is a laborious task but it saves tons of memory.

WaveEditor on Android for me

Hi @CJ_Monster,

This is a stereo mp3 import inside Audio share on iOS:

Hi @Jean-Michel_Rbt

Thanks for your message.

To allow our engineering to further evaluate your issue, please provide us with the following information and files.

  • Which device (mode) and OS version do you use?
  • Which Cubasis version do you use?

In addition, please provide us with screenshot of your project directories.
Please create these following these steps:

  • Launch the iPadOS Files App
  • Go to “On My iPad” / Cubasis 3 / Projects /
  • Make a screenshot
  • Open each folder (Audio, Audio / Backup, and Backup), and make a screenshot of the list view

Thanks
Lars

Thanks for the information

Thank you. I don’t even understand why files are copied, normalizing (in the clip edition context) is just applying a gain, right ? May be for real time playback purposes ?

17

Yes hopefully !

Thanks for the tip.

I think the destructive normalize was primarily done for performance reasons back in the days when devices were slow and it has stuck until this day…

Ideally we could have something like ‘audio event properties’ that define things like event-gain, event-direction (forward/backward), event fade in/out, event pitch, event-stretch and all these parameters could then be automated when needed using an event envelope curve.

Changes to event gain could be reflected on the waveform on the screen as one example.

I have ZERO clues on what @LSlowak and his team have planned for future updates.

Personally I still hope to see the Cubase Sampler Track find its way to the iPad version of Cubasis…

Hi Lars

Samsung Tab S9 fe, Android 16, one UI 8.0, Cubasis 3.8.3.

What are the app and procedure to access content on Android ?
