Hi guys, I'm looking for a plugin to use as an instrument tuning effect that displays the fundamental frequency for the note/pitch your playing at. Now this effect would use that number to control a volume knob that will turn the volume of the audio up and down in real time with the changes in the fundamental frequency. I'm not trying to create one envelope for a separate band, i'm trying to use the current fundamental frequency(like a guitar tuner displays the current frequency) to control the volume of the effected tone audio in real time. So imagine a guitarist looking at a tuner and holding a volume knob, When he sees the pitch/frequency going down, he turns the volume knob down at the same time, and when the pitch goes back up he turns the volume knob back up at the exact same time.

Could you please help me with the name of any such plugins ?

Welcome,

It sounds like you are wanting a mastering tool that shows the fundamental freq of all the instruments ranges from 20hz to 20,000hz which can be set up to allow a similar way to add or reduce frequency bands like a 31 band graphic EQ, but at a larger scale covering the full 88 notes in chromatic steps like piano per-say, yes?

With adjustable frequency and low-pass filter controls to shape your ultra low-end, LoAir .... A true timesaver, the Vocal Rider plugin rides the levels of vocal tracks ..... The Waves GTR Tuner is a chromatic tuner that can be set to Standard, .... musical balance, the Linear Phase EQ plugin provides precision control

Hey Chris, Thanks a lot for the help. I've looked through all of your replies and They're quite helpful. My only problem is that I need the plugin to be in real time and adapt to any instrument I throw at it. It's input source should be only the frequency being played and the output volume should vary according to it. For eg. If I play 10 Khz Volume should be 100%, 9 Khz volume at 9% and so on and so forth. Just to give an example.

I tried this effect called pitcher on fl studio and it followed my my changes in pitch perfectly but the downside was that it was only a pitch correction plugin like auto-tune, and it doesnt have the ability to control volume. So if there was a plugin that detected real time pitch/fundamental frequency and use that amount to control volume in real time then that plugin would be exactly what I needed.

I'm not sure of such a plug-in (yet) but we are getting closer to what you are needing. Perhaps we can keep brain storming until we attract more members to chime in.
In the pro audio world we have a process called side chain . Are you familiar with side chain ?

Side Chaining Compression & Ducking
Frequency Dependent Side-Chaining

A standard process to control the amplitude of a particular note or area of frequencies can be controlled by connecting an EQ or frequency filter to sweep or pin point the suspect area, then force a compressor to dip or increase that freq in real time.

I might be missing the point of why you would need or want this and excuse me for being blunt but why are you not using a volume or gain control instead ??

It sounds to me as if he wants a note to trigger a rise in amplitude for a particular frequency/note. I'm not aware of a plug that does this, at least not yet, but Chris's suggestion of using a sidechain makes the most sense, in that it's not necessarily raising the note itself, but attenuating the gain of everything else but the note/frequency that is wanted...kinda like a sidechain de-esser, but in reverse.

a multi-band compressor might also be able to do this - to some degree - if you chose a very tight Q on the frequency you wanted, and allowed it to pass, while attenuating everything else around it...although you would need an incredibly tight Q for this.

just kinda thinking out loud...

I came up empty. Just more compounding ways to sort of get this done.

Anish, you may need to share what you are wanting this for but I get the feeling you are designing something around this concept so its not something you want to share, publicly.

What you need is based around side-chaining upwards or downwards ducking with an auto-tuning, freq tracing device that will trace and duck the frequencies in real time. It doesn't sound like something that can be done in "one step". But, I'm sure there is a way. Digital audio can get this done. The question is, what are you doing it for and then finding a coder to get it coded.

You might need to approach a coder with a confidentiality agreement.

Good one Kurt, I suggested this in passing early on using the Piano role or keyboard as the source. He needs it to trigger a wave to midi converter from ( it sounds like an OTB source) though. This could happen in stages by converting the source into midi, then trigger either an upward/downward sidechain compression ducking.

But he needs this in "real time". and that doesn't seem possible if he is in fact, hoping some mono instrument is the source in real time.

Melodyne note to midi is the answer to get the audio into a digital freq that can be freq traced. Its how I fix bass guitars that are terribly played or tracked bad ( massive room bleed etc). The question is, real time from something that is other than just a keyboard..

The problem is ( which the OP isn't being to open and clear on) is what the actual source is?
It sounds like a guitar solo or some sort of single note instrument (which could have intonation inconsistencies as well) other than a electronic keyboard. I agree, if the source is already midi, it would work.
What ever it ends up being, can you imagine the latency of an organic instrument/ wave file being converted to a midi file, then side chained in real time all through AD conversion? Its sounds pretty busy.

Are we on the same thought or are you reading into this different than me?

i don't think it matters what the source is. guitar, vocals, what ever ... as long as there's a "pitch" to it it will frequency dependent trigger through a side chain, a compressor. op says in real time so this works even if it's playback off DAW .... if we are using plugs to compress we may have to record everything and then line it all up but a simple hardware compressor will do the job.

Thank you Chris, Kurt and PC record. As for the being evaise, I'm not actually. To be blunt, I'm doing this for a colleague and he's being clear as he can be . But the part about why he want's to do it, it's still not 100% clear. To an extent, I think it's for a live stage performance or something similar. He's a DJ BTW. And Chris, I've checked out the video. May be it's on to something. I'll give it a deeper look and get back to you. Thank you.
