# vocalist wants to hear reverb whilst singing

I was wondering how to route signal for this problem:
A vocalist wants to hear reverb whilst singing, but I don’t want to hear it and I don’t want it on “tape”.
And...

Given a speed of sound of 335m/s, what is the wavelength of a sound with a frequency of 200Hz? To answer such a question where is a good resource on the net? I have a few similar questions that I'm a bit lost with that are similiar.

This will help me out a lot.
Thanks.

The speed of sound equals frequency times wavelength, so for that temperature, the wavelength of 200 Hz. would be 1.675 meters. That speed of sound corresponds to a temperature of about 7 degrees Celsius. Better is 344 m/s, which would give a wavelength of 1.72 meters for 200 Hz.

Is that a wee bit of doppler effect on that 200hz, David?

You have to tell us what your recording medium is before we can answer that. Basically, though, what you would do is use a send on the vocal recording channel to go to a reverb and route the return of the echo only to the headphones, not to anything that is being recorded on the same track as the vocals.

Rockaroo,
I'll answer the easier one and let the engineers talk about the weather `
Hopefully you have some sort of analog mixer at your disposal. If you don't this advice is worthless and you may need some alternative way to monitor the processed signal or creatively use your outputs. Describing your set up would help us to help you better.

You need some sort of alternative send to the reverb unit that folds back to the headphones/monitoring system mixed w/ the original sound.

There's lots of ways to do this - inserts/ aux sends/ buses/sub mixes etc...
But the key for you would be to not print (record) the effects loop and hopefully not have to go through the computer to do so.(if that's what you're using for effects) Record the original track and have the vocalist monitor the effects loop, send the output of your effects mix to the singer. You (as engineer) can monitor the original input. Hope that helps.
