I am in the process of creating a test tone and reference cd.
I am referencing the ideas of Hugh Robjohns in his Sound On Sound article from Sept '03.
For creating calibration signals I am using Sound Forge 6.0.
My sound cards are a Delta 44 and Gadget Labs 496.
I am using a Tascam M30 mixing board which has unbalanced connections.
I generally track and mix through this board (to the computer at home and to a VS880 "on location").
My monitors are Event 20/20 passives (if thats relavant).
The test CD will be played through an external CD player hooked directly to the mixer.
I want to have as complete a test CD as possible.
I just want to make sure I understand the levels involved.
O.K. so......
My 1st question is what do I need to set the test tone levels to???
The article mentions a GLITS signal set to -18dBfs.
Is the Sound Forge meter in decibles equal to dBfs's???
i.e. do I set the level of the tones to -18?????
By default the stock SF test tones (both FM / Sine / and DTFMS??) are at -12dB.
My next question is, when I run the CD, if the reference CD levels were burned correctly then my VU meters should be at 0 for these test tones, yes????
And finally should I be setting up for -10dB, 0dB, or +4dB test tones with my M30.
I think its -10 on this older board, but I do not have the manual.
Thanks for all your help in advance.
