The file review portal is a collaborate space where you can send audio files, such as mixes, to specified recipients for review. These recipients are able to listen to the audio files in lossless quality and add comments within the audio timestream as points of revision requests. As the studio, you can view all comments, share feedback on the review comments, mark comments as "Complete" or "Rejected", and so forth in managing the mix feedback.
The File Review module allows you to remove the complicated, ineffective feedback loop away from text messages, social media messages and emails (which is often a combination of many of these for a single project, further complicating the management of this feedback!), and more efficiently manage all your audio file review feedback within a single, intuitive application.
