If you are going to record your band, act, group, VoiceOver, audio book in the studio do not expect or assume that your recording data (session) it is save in someone else's computer or other device, save keeping it for you.
Many people assume that recording studios are also digital libraries that one can come back to at a moments notice and get access to their own music even years after it had been recorded.
In most cases it's just wishful thinking.
Hard drives, computers do stop working resulting in lost of DATA.
If your music is that precious to you why don't you make sure that you keep it save instead of relying on others to do so for you.
You need some form of digital storage to save keep all your work like a hard drive, flash drive USB or your personal computer.
I suggest to back up everything as often as possible.
The other issue here it is data transfers.
Everyone this days just ask for the data to be sent via internet with transfer sites such as iCloud, Weetransfer and others.
This services are deliberately slow when it comes to files transfer. Unless one signs up for it and it pays its regular fee.
Who can blame them? That's how they make their money.
What many are not aware of is the size of the files for instance: An average of a MP3 song it vary's from 2 to 8 MB or more whereas a WAV. AIFF are about 10 times that size.
This are the type of files that most studios record with, being higher quality of audio of that of a simple compressed MP3 file.
Bear in mind that slow internet speeds also play a great part in it.
In hindsight many expect that the sound engineer will send all the data after the recording session it's over in their own time and for free witch it can take hours and in some cases day's.
That not fare on the studio nor on the Sound engineer that done your recording.
Having an hard drive or flash drive USB to store your music it's a quintessential must this days.
Don't expect that once you"ve finished your time in the studio that it's just a matter of transfer it over into your storage device.
Not all studios, home studios use the same DAW most common are Logic, Protools, Studio One, Cubase, Cakewalk and many others.
To ensure that your music can be accessed by other DAW's operating systems on either Apple or PC's or others for that matter.
All audio files need to be exported as Stems on a format that is compatible universally with all DAW's and their operating systems.
And this also can take a long time as files need to be check and double checked as some can become corrupt in the process.
It's time consuming stuff.
When you want to come to the studio and record your half done project that you have worked so hard at your home studio you must make sure you prepare everything as needed and to the right requirements.
You must treat and organise your files like a librarian in a library.
Generally creating stems it's best.
Also, it's important that you have as much info as possible about your project such as tempos, time signatures, and song's arrangements. In this case the more info you have the better.
As you take your data to the studio remember that your storage device may not be compatible with the computer, operating system of that studio.
Make sure it's readable and writable and it's formatted to the right specs.
Always consult the sound engineer.
It's your music, it's your data no one else but you should be responsible for it.
