Grub Tune Tester

GTT is an online tool to test your GRUB_INIT_TUNE beforehand.

How to use

Just enter a GRUB_INIT_TUNE using the following format:

tempo freq duration [freq duration freq duration...]

Where:

• tempo is the base time for all note durations, as beats per minute. 60 means 1 second notes. 120 means 0.5s notes, etc.
• freq is the first part of a note. Indicates its frequency in hertz. 262 is a Middle C. 0 means silence.
• duration is the second part of a note. Indicates its duration measured in bars. With a tempo of 60, 1 means a one second note, 2 means a two seconds note.
