Default Vocal Doubling - multple voices

Hi I created a vocal recording and I want to duplicate it so it sounds like two people singing. Right now f I duplicate it and put it on a new track it just sounds louder, not like two voices. Help! Thanks!!

If you can actually get the singer back you can look for an "automatic double tracking" (ADT) effect or a chorus effect. ADT varies the time and phase to get a more realistic effect but it's still an "effect" and it's not the same as true double-tracking.

Right! mixing is done by summation and you are simply doubling the amplitude of each sample.


If you invert a copy an mix, you'll be subtracting (adding a negative) and you'll get dead silence.


If you actually double-track have the singer sing twice and record twice, that won't happen, and if you invert they will mix normally without "subtracting".

Track the vocal again on another track. You will still sound like you twice, but as DVDoug says, you can tweak that using delay, phasing, even different pan & reverb settings.

I just did a tool for exactly this, which might or might not be helpful for you.
I crafted a JSFX that provides a "humanizedly fluctuating" Midi CC (14 Bit).

I installed this thingy three times and one controls a ReaPitch for intonation fluctuation, one controls a ReaDelay for timing fluctuation, and the third controls a "8*Stereo to Stereo Mixer" for volume fluctuation.

If you are interested in it, I'll upload the "Midi CC fluctuation" JSFX to ReaPack.

Here is the FX Chain:

Michael,

Please do upload it I've been searching for it in the stash and in your reapack but I guess it's not there (?) Would like to try the humanizedly fluctuating intonation and timing

## Description
MIDI CC fluctuation generates a randomly fluctuating 14 bit (high resolution) CC Midi data stream.

The fluctuation is generated by randomly increasing / decreasing the current CC value. The way this is done, can be "humanized" by several parameters.

"Midi Channel" selects the midi channel to output the CC messages

"CC" selects th CC number. As High resolution CC is used only CC#s 0..31 are selectable.

"Delta wide (^1)" controls the amount linear value of the random delta increasing / decreasing the output

"Delta mid (^3)" controls the amount a value of a delta value that covers less of the extreme ends

"Delta narrow (^5)" controls the amount a value of a delta value that covers even less of the extreme ends

"Hold speed" for humanizing a directivity of the fluctuation is implemented. This parameter defines how of then the direction and migrating speed is supposed to change

"Hold mix" defines the intensity of the directivity vs a purely random walk.

"Speed (Roughness)" defines the factor of the random value that is added to the current output value.

"Result wide (^1)" defines the force to pull back the output to the center in a linear (proportional to the displacement) way.

"Result mid (^3)" defines the force to pull back the output to the center in a way increasing with the displacement

"Result narrow (^5)" defines the force to pull back the output to the center in a way increasing with the displacement even more.

"maximum step" defines the step size (per audio block) to the raw output is allowed to fluctuate

"gain" and "bias": values to multiply the output with and to add to the output.

The other sliders show the generate signal in realtime:

"Delta": the current raw random delta value

"Hold": the current hold value

"Delta with Hold": value to be added to the raw result

"Result raw": Result before applying gain and bias

"Result -1 ... 1": Normalized output value

"Result Midi (0 ... 16383)": High resolution Midi CC output value

A graphics shows the history of the "Delta with Hold" value in blue and the history of the output value in yellow.

I just uploaded an improved version to ReaPack (including an improved description).
