You have certainly learned a lot in a short time. I have been reading and experimenting diligently since I got MC and spent several hundred dollars on mics and other gear, so I think you have proved to me the value in learning to work with what you have available, ie a "mic from your science kit"!! Incredible!! I am very impressed with your recording and the process you used to get there.

Thank you for the feed back. I have started work on the song Beatiful By Christen Aguleria (or however you spell it) but so i am not repeating myself I am re-working the song some what. But the main forcus is on getting an even higher vocals quaity.

Very creative effort, the mix is suprisingly good after all it went thru to get there. I beleive you have a very good understanding of how audio files work, that will pay off in the long run. Keep up the hard work, keep experimenting with sound, and as time goes on gather some better equipment, as funds allow, you have talent.

I am quite proud of these vocals.

Firstly I have no monitor system so I turned the Bass and Treble right down on my Hi-Fi and moved the mike as far away from the speakers as possible with it facing away in my mike stand.

The mike is a free one that came with a DK Science kit I got for Christmas. Itâ€™s a high noise and low output mike and so basically the vocals are just above the noise floor.

I used my Digitech Bass Effects Pedal to pre-amp, I had to use the full power of the pre-amp and the signal still wasnâ€™t very strong. This also brought up the noise floor.

I then took that signal into my 10watt guitar amp (I have been inside this amp and added a pre-amp line out) and used the pre-amp in that. So now the noise level is very high.

Then I recorded into cakewalk, through the â€œLine Inâ€ on my computer. When I recorded, the signal only reached about 24db and the noise floor was 48db. I listened to the track and signal was weak and the noise floor was high.

Here it the clever bit:

I loaded the wav file into Audacity and used the noise removal tool. I took time to creator a noise profile that was just noise not just a bit of the signal that looked empty. When I did the noise removal at first I used a very high setting: but this removed almost everything from the track. So I kept on doing it till I fold the lowest setting that would remove the noise but keep the vocals untouched. I then created this wave and loaded it back into MC.

Now I changed the scale on the db axis in the track view so I could see where the vocals were in the track. I used the auto-mute envelope and mute everything that wasnâ€™t words. I wanted to add reverb to this track and I realised that the auto-mute would mute everything including the reverb, were as in real life natural decay would let the reverb decay over to muted parts.

I added a BlueCompressor set for a very heavy compression in real time. I then bounced the track, with the auto-mute and compressor, to a new track. Now I had a plain wav file with the effects of the compressor and auto-mute built into it.

I added a BlueParaEQ in real time; I basically used the Warm acoustic pre-setting but added a little more top end.

I added a Reverb (cant remember the name), it was a heavy reverb but with a low mix value.

On the Aux send I added a HF Exciter (install the kinetics demo and you get loads for free plug-ins) set to â€œneed a liftâ€ with a lot more mix than the pre-set.

And that is what this 14 year-old did with his Friday night.

And I think that is everything. I will spell check this later but I have a bass lesson running late

Sounds great! I have Audacity as well but the noise eliminator distorts my recording. How did you get yours so clean?

Well I found one of my own, the onw build into Audacity, and i am have happy with the results have a look.

try bluegate (google and you'll find it). I use it with satisfactory results. Robo, however, is on the money. First try to eliminate room noise, second, try and eliminate noise from your setup. May I ask why you pre-amp your vocals twice. You are probably adding unwanted noise. Robo's mixer siggestion is a good one. Alternatively, jack your mic directly into your sound card. To boost the level and quality of your vocals, clone the vocal track two (or more times), and add effects and eq. For example, I typically take the vocal track I like, clone it twice so I have three of me, add reverb to one, compressor to another, leave one clean, pan them a bit, eq each track a little differently, mix them down to one stereo track, and perhaps add a little more compression and / or eq. Experiment with these types of techniques and you should be able to generate decent quality vocals without adding noise, particularly if you have a crappy mic. I have succesfully used Bluegate to remove traces of my background tracks that my condenser mic picks up from my headphones.

There are some plugins and stand alone programs to use, I must say that they will have only marginal results, the problem is that the noise is embedded into the mix, and to remove it one must isolate it and erase it, this usually causes a certain amount of degredation or al least distortion of the surounding material.

The key is to rework the setup and process you use, eliminate most of the noise to start with. This can be done by purchasing a decent small mixer, I suggest the behringer 802 directly connected to the sound card and do all inputing thru that.

Having said that for a cheap fix download audacity and use it to remove noise, there is detailed information in the help section on this subject.

Ok does anyone know were i can get a free noise remover. I dont care if it is a DXi/VST plug-in or a stand anlone program.

Home recording using a Â£10 mik, pre-amped through a bass FX pedal then pre-amped through a guitar amp then recorded and compressed on your computer leads to a very high noise floor.
