Upload an audio file can a be problem if your server has a low upload maximum size limit. (e.g 4M).

Here is a way to work around this.

Use the following tip if you need to increase the upload_max_filesize on your webserver, especially if you are not able to directly access/edit the php.ini file.

1/ Create a new file and name it php.ini (the name and the extension are very important).

2/ Open it with any text editor and paste the following lines:

upload_max_filesize = 40M
post_max_size = 40M

3/ Then, save the file and upload it to your wp-admin folder.

In your jPlayer panel you should now see your new upload size limit at the bottom of the page, below the line “Your server info”.

Now you will be able to upload audio files (mp3/ogg) up to 40M.
