Let's say I want 2 build circuit that can remove a certain frequency omitted from the original source on is return but leaving the fabulous music we play intact. Does that help?

No. Forget about building any equipment.

You have a problem. The problem is there is "hiss" coming from your equipment. This is not normal.
Fix the faulty equipment in the first place.

No.

 

I know what u gonna say y o y o y did u not say that in the start an y u insist on speak in txt SPK it v annoying an such. But hay u only live once yolo

And skip the cool attitude. If you want help, that kind of attitude will get you no points here.

So do the folk trying to help you. Why should they have to struggle to translate your post?
I agree with post #61.

OK soz u rite bout dat . but say I can t fix me ikle problem is there any components I can utilise 2 remove an original htz from the first signal from the returning signal. Please boyz thro me a bone here godamnit

Didn't they teach you proper English in school?

I would think any sound man worth his pay should be able to do that. If you can't find anyone that can do it then it likely can't be done.

And enough of the text speak already. How old are you? 2?

Hello,

@Jontyleff , being from the UK, I would expect to see correct english.
You are talking gibberish and often make no sense.
Please use correct english and not shorthand or the gibberish talk.

A hiss is not a specfic frequency, it is what is called white noise, which is a mix of all frequencies. That is why you need to find the source of the hiss. Any filter you use to take it out will affect the music. Does your band use cymbals? Guess what is a large component of the sound they produce.

OK so our band plays live music and we record or performances so I need 2 build a device that can cancel out the very high pitch frequencies that come from imperfect sound equipment so that our recording sound great. So a circuit that can remove certain returning frequencies leaving the music intact

I nearly spit my coffee onto my laptop! What a hoot to finally learn you want to make $shit sound like $hinola when it's recorded.

Heed what's been offered. Adding additional processing between the musicians and the recording is NOT the right approach. Cleaning up that process at every step (the instruments, the musicians themselves, the amplifiers and speakers, the room acoustics, the recording microphones and equipment, etc.) will lead to a far superior result. You'll probably improve the experience of your audience along the way, if that's something you care about.

If you absolutely cannot solve the problem at the source(s), the filtering you want to accomplish is relatively 'simple' in software although not without side effects.

 

Hey can any one in you're site please please please please give me just one RX

I've done this before to remove 60Hz. Before I even will discuss the circuit, I need the original poster to CLEARLY state what information he is looking for in the "return" signal. I've read through the ENTIRE thread (pretty much a first for me) and I am as unclear now as to what the goals are as I was at the first post.

The problem is coming from your vintage Marshall Amp, the one with the volume knob that goes to 11. Just keep it at 10 or below and the hiss will be gone.

I think, even with my bad spelling, I could win a spelling bee with this guy. Technology is making these kid dumber & dumber.

 

Like Spin said in post #67. Don't most record from the mixer board input?

This is kind of sounding like he wants to "pirate record" a band, not record one he's in.

Therefore, if all he wants to remove is "hiss" then software is already capable of doing this...to a degree.

Please SKL001 can u explain what components you used to remove 60hz in your project please. That will be really helpful. I know I have got off on the wrong foot with your community therefore they will only discuss subject rather than object... Understandable. But I really just need to be pointed in the right direction and I can take it from there. Can you please explain how you managed to remove 60hz, what process did you use, which components, much appreciated, many thanks Jonty

 

To All About Circuits community. Apologies if I aggravated your community with 'TXT speak' and for not making it clear from the beginning what I was asking. So from now on will only use The Queen's English. It's a learning curb brothers and sisters will try harder next time. New member and all that.

Doing it from the mixing board there should be no hiss, if there is, the mixing board is the problem. The mixing board takes sound from each instruments amplifier and mixes it to a single output that is then sent to the PA (public address) system. That sound is what people in the venue hear, not the sound from the individual amplifiers.
