How to DIY a Test CD - Click HERE for Original Thread
GeorgeBoles
Evening All,

I am in the process of testing my drivers for a subwoofer project I am working on. Their resonant frequency is about 21-23 Hz. Unfortunately the el-cheapo oscillator I have has a huge "gap" at about that frequency.

Is there any way of making an audio CD which has sine-wave test tones in 0.2 to 0.5 Hz steps so that I can use this with my nice CD player as an oscillator?

I have the usual stuff which comes with Winblows XP and 98, and with Soundblaster Live! card. My brother has some snazzy mixing programs Cake Walk, Cubase, Fruity Loops, SoundForge.

Can any of these do the job?

Regards,
GB
