Downloading and Sending Files



Sending and downloading ON-DEMAND services: Mastering.


Your downloads section on your User Profile page, corresponds only to your work order, instruction manuals for sending files. Our system, for security reasons, has not been programmed to make any changes to your user profile page, as set out in our Privacy Policy and Terms of Use. 


With this in mind, together with the fact that ON-DEMAND services (mastering) are carried out in a unitary and personalized way, deliveries are made through external file sending platforms. Such platforms use advanced encryption, secrecy and security technologies and are the best device available on the market for exchanging files. This means security for sending files for editing by USERS for editing, which extends to the delivery of files finalized by LUFR.

Therefore, the link sent by our system by email, and the link available on your User Profile page, contains two informative files, one of which is a thank you for your purchase, and the other a manual for file submissions.

Manuals with all download information, User Profile page illustrations, where to find your work order number, shipping procedures for each product type, are available for download from our Support page. If you prefer, click here .

For questions, access our faq here , or contact us by email , we will respond as soon as possible.

1 File submission procedure for ON-DEMAND editing:


1.1 After purchasing your Editing, Mixing, Mastering, Sound Design package, a service order will be generated that will be sent to your email, and will always be available on your User Page in the MY PURCHASES field.

1.2 Your service order number is identified as "order number" on your payment invoice sent by email by our system, and is always visible in the MY PURCHASES field on your User Profile page. We need this number to assign the start of an on-demand service to a file uploaded through our website.


1.3 You must access the File Upload page on our website, fill in the fields of the submission form with your data registered on your User Profile page, used during your purchases on our website.


1.4 In the URL field, the USER must insert a link to share the file generated by the platforms described below in this paragraph. Note that each of them has particularities such as the size of the single shipment, link duration time, free shipments or paid plans. Choose the one that best fits your file size. Visit the platforms official website for more information, or visit our File Upload page here for some basic information about the platforms:



Note 01. When sharing your link in the environment of the sending platforms, use the email address: as the recipient. However, we will only access the links sent by the submission form.


Note 02. Preferably, send a single link with all your material. If this is not possible, you can use the File Upload form more than once, with different URLs for editing. But remember to enter the same Service Order number in the relevant field, so that we can compile all your files in a single folder to perform the ON-DEMAND service.

1.6 In the "Message" field, the USER must explain in as much detail (there is no need to use technical terms) what he expects to be done in his ON-DEMAND service, for example: short pauses between the lines of the podcast , vocals at the same volume as the instruments, bass or loud guitars, streaming-only mastering, bass kick, distorted bass…

1.6.1 Also in the "Message" field, include information about BPM, Tempo, and if there are tempo changes, in which measures these changes take place.

Note. Only Spotify, Apple Music, Youtube, Soundcloud, Bandcamp and Vimeo links are accepted, we do not have access to all streaming platforms, so if the user is premium on Deezer, Tidal, etc, and does not have access to the sharing on Spotfy, or the reference is on some social network, the user must look for the (or other reference) music reference; movie; or podcast; on youtube, or on another platform described here.
