Rattle-checking mp3 downloads?

[Mannginger]

Hiya

Odd question but does anyone know where I can get some mp3 or similar files to test where rattles are in my car? My new toy has developed a rattle on Driver's side door and I want to pin it down but I can't when driving. I'm sure there used to be CDs with low frequency sound that would do this job but my google-fu is failing me currently. Ideally I'd get a download rather than CD

Cheers in advance

I'm not sure how your tech-fu is, but on YouTube you will find plenty of videos that are just 20/30/40/50hz etc.. tones.

Plenty of download programs (eg. JDownloader) can rip the sound of it for you
