For the moment, we can't accept any files over 1GB, so be sure your file size is within the limit before uploading.
The file you upload must be at least 128kbps (if it's lossy), and we do not accept surround files. If you're unsuccessfully uploading a surround file, please re-export your project as a stereo interleaved file.
Give the upload a little time — big files may take a while. If it’s still not loading try emptying your cache and restarting your browser. If you’re still having trouble, please get in touch via email@example.com and we’d be happy to help out.
