You may send your audio files over the Internet using one of several file transfer services.  We recommend WeTransfer.com.
They have a good track record of transferring files and you can transfer multiple music files up to 2GB.  Now that's a lot!

Keep in mind that internet file transfers do take some time.  How fast your songs upload will be determined by the size of your files and the speed of your internet connection.

WeTransfer.com is easy to use and you don’t have to register to use the service.  You simply fill out a short form.  It will take you less than a minute.  You simply add your .wav or .aiff files, enter our upload e-mail address ( listed below), enter your
e-mail address, a short message if you like, and click transfer.  It couldn't be easier.  It's quick and efficient.

Note:  Do not create a .zip folder for your file transfer.  When using WeTransfer.com, your music files will be compressed and automatically inserted into a .zip folder.  The .zip folder provides a much faster upload.  Your music files will be extracted on
our end and decompressed with no quality loss.  If there are any errors created during the transfer, we'll know immediately because a .zip folder will not open if it is corrupt.  This will help us validate your transfer in a timely manner.

Use our Audio Upload Center address as the recipients e-mail address:  upload@cdmasteringservices.com

If you're sending files over the Internet, be advised that work will not begin on your project until payment is received.
