Mix Preparation and the Technical Specifications
to Optimize Audio Post-Production Workflow

If you have confirmed and officially booked a mix session with our Studio Directors via booking@flavorlab.com, then we are ready to receive elements! On this page, we would like to briefly answer some frequently asked questions about our workflow and provide a list of technical specifications to assist you in the preparation of your sessions.

There are various types of audio files that exist. What audio file types is best to work with? In order to ensure the highest quality end product, please use .WAV files for all audio when possible. .AIFF files are also an acceptable alternative. Please avoid MP3 files as this file type causes considerable quality loss. High resolution stereo music tracks are often available for download directly from library houses. We are happy to consult any other methods to acquire high resolution audio tracks.

What elements/files should be sent for the mix sessions? Before the start of each session, we like to receive the following elements:

1. OMF/AAF File(s)
2. Quicktime Reference Video(s)
3. Any other audio files that can be sent separately to offer flexibility to improve your mixes.
Examples include previously recorded Voice Over files, full non-edited Music files, any production sound or dialogue bites.
4. Production documents with Retag information and/or scripts.

What is the best method to deliver the elements? We work with multiple ways to receive the elements so whatever is easiest for you! If you are using an…

1. Online file transfer service or website: please send the download links to booking@flavorlab.com. Hightail, Dropbox and Wetransfer are examples of online services that have been frequently utilized.
2. Internal FTP network: please provide us with the appropriate login credentials so we can access and download the elements.
3. We can also provide a login and username so that elements can be uploaded on our transfer system. Email booking@flavorlab.com for instructions.

What are the technical specifications that should be incorporated in the OMF/AAF and Quicktime files?
(To optimize the efficiency of file uploads/downloads and the consistency of data transfer, please consider the following parameters for OMF/AAF and Quicktime Exports.)

Please insert a 2-pop (One frame of a 1kHz tone), exactly 2 seconds before the first frame of the program/video. This is to ensure that we appropriately synchronize the Quicktime to the audio.
