Vocal recording-Extern Mixer and studio mic Problems!

Baseline-One · Sep 20, 2008, 07:49 PM

need help pls.
i have an T-bone 400 studio mic and an Behringer eurorack ub1204 pro
connected to the line in.
ok no problem with that.
my problem is i need help with the dsp to find a way for clean recording ,i have to much backround sound in the mic.
i tested the noise gate plug and the compressor plug but i didnt get it working like i need.
anyone can help me out ?

thx

if the mic is picking up background noise along with the audio you want to record - no kX DSP plugin will help you.

The Noise gate by design - will simply mute low level background audio - then automatically un-mute when the noise gates threshold has been breached.
So, you set a noise gates threshold just above ambient noise levels - the noise gate will be blocking audio from passing through it - and when audio you want to record - and should be louder than ambient noise - will be greater than the threshold levels and allow audio to pass

A compressor - is designed to amplify weaker sounds more than louder sounds - thats what 'compression' is - so .... the best answer is to eliminate that background noise mechanically (move the mic into a sound proof room) instead of electronically (using any plugins).

You would need to specify what plugin(s) and ask specific questions on how to use that plugin for anything more specific.

my idea was to rebuild hardware like spl channel one .
i have an room for the mic ,simple but ok .my pc is very loud so you can hear it in the mic. i thought that i can rebuild it with the plugs noisegate/compresor/maybe limiter.
but i cant find out how to make.
maybe i have to buy hardware

I would be suprised if the SPL Channel one would do much to remove the PC's noise. Try using low noise fans and noise dampening in the PC. or, you could get extension cables for the mixer to sound card - and move the PC to another room. If you are a lone recording engineer & performer - a wireless keyboard/mouse and monitor extension is another possibility - many DAWs can use a MIDI keyboard as a remote control (start stop/record etc..) too.

Its *always* best to remove the noise mechanically - any electronic solution will color the sound in some undesired way.

You could try to use an EQ to reject the noise?? but the nature of noise is to not necessarily be of any particular frequency.

the spl can remove much noise but it cost 1000€
you can do it so that you level your mic around what you need. all the rest will filtered out.
maybe you stand in front of your mic (30 centimeter,dont know what is in inch) all after 30 centimeter will filtered out .but thats hardware ,i hoped that i can do it with the plugs in kx mixer for clean sound.

well - I guess something is possible to sorta emulate, but a $100 sound card (even worse - AC97 based input) vs a pro $1500 mic preamp - erm, is like comparing apples to pomegranates - don't you think? I would think this is only feasible with a choice of mics, or at least with adjustable sensitivity. The mic either picks up the sound or it doesnt - and if it does - you need extremely high quality filters to reject noise and *not* color the sound in a usually undesired way.

When it seems much easier to me, to eliminate the noise to begin with. Its not hard at all to replace PC case fans and even CPU fans - even easier to move it and use good quality extension cables (unles you are a one man operation for everything..?? makes this way a bit trickier) and wayyy cheaper than $1500 SPL hardware.

I guess if its a challenge - then, perhaps others can come up with some ideas that more address your question directly.... but I have doubts anything will compare to the SPL hardware.

I am in Maddog's camp here. We record in the same room as the PC so we build a wall of blankets and/or foam around the mic, basically a temporary, sort of sound proof, closet. That eliminates a lot of room echo and PC noise and helps with the passing traffic and birds.

Our condenser mic, without any sound isolation around it sounds like it is in a barn, even without the noises.

If you have background noise, you have to eliminate that noise, not to clean up the signal from the noise. This is an essential rule for serious audio engineering, since every signal processing degrades the signal quality in any kind.
