Reply To: Music File
You can use an FTP application to upload the file. It’s best not to modify upload restrictions from WP or PHP settings as it can lead to a security problems.
You can create a folder outside WP for those files. eg. /mymedia/music/ and upload them and play that file using the uploaded file path.
The player streams data , so it won’t that slow. Depending on the encoding it will have differences.
