Alright, thanks for coming back for my next installment in this article series concerning audio effects. In the past few weeks we have covered quite a few commonly used effects, such as reverb, delay, flange, and compression. These effects all have wide scopes of usage, and are probably used on a daily basis in most modern recording studios, on a wide range of different musical styles. We were discussing the basic functionality of each effect, leaving you to decide if and how you would end up using it in your own production process.
Today we'll be moving on to a couple of other types of effects, which are probably less used that the others we've talked about. Don't let that fact deter you from reading any further, as these two effects; vocoder and auto-tune, are both very flexible and powerful tools for you to add to your studio arsenal. So, please strap on your learning cap and follow me.
Vocoder
The vocoder (its name being derived from "voice encoder") is a speech analyzer and speech synthesizer. It was originally created for use as a speech coder for the telecommunications industry in the 1930s. It was used for secure radio communication, where voice has to be digitized, encrypted and then transmitted on a narrow, voice-bandwidth channel. The way that the vocoder works is that is finds the basic carrier wave that the human voice produces. This carrier wave is at the fundamental frequency (the lowest frequency in a harmonic series). Is is then measured how its spectral characteristics are changed over time by recording someone speaking. This results in a series of numbers representing these modified frequencies at any particular time as the user speaks. To recreate speech, the vocoder simply reverses the process, creating the fundamental frequency in an oscillator, then passing it through a stage that filters the frequency content based on the originally recorded series of numbers. For musical applications, a source of musical sounds (such as a guitar) is used as the carrier, instead of extracting the fundamental frequency. The vocoder is famous for creating robotic sounding voices, and has been used in film to create; surprisingly, robot voices.
Auto-Tune
Auto-Tune is used for correcting pitch in vocal and instrumental performances. It works by employing digital signal processing algorithms (many which are drawn from the geophysical industry) to continuously detect the pitch of a
periodic input signal and changes it to a desired pitch. The harmonization is intended to increase the musical quality of a vocal track without revealing the singing as processed. This works well in a studio environment to correct the performance of vocalists and musicians, after they have recorded their takes. It has also been widely used with extreme parameter values to create a distinct electronic vocal sound.
This wraps up the 5th installment in the DiskFaktory Mastering article series on audio effects. Today we covered a couple of the more fun to work with effects, in my opinion. I myself have learned quite a bit writing today's article, and I hope you feel the same way. Now we're much better prepared to create a symphony of robot voices.

Korg R3 Synthesizer / Vocoder Keyboard 889406770768 $509.15 The Korg R3 is powered by the MMT (Multiple Modeling Technology) analog synthesis-modeling sound engine and delivers 2-timbre/8-voice performance in an easy-to-use 37-key 'board. 128 programs deliver crucial synth sounds from leads and pads to strings and percussion with 2 oscillators, 3 envelope generators, 2 filters, an amp section, effects, and a noise generator available for each voice. In addition to the vocoder which works with the onboard mic input, it has a modulation sequencer for precision 16-step control of modulation movement.MMT synthesisThe versatile range of built-in oscillator algorithms covers everything from familiar analog synthesizer waveforms, to unique digital waveforms and even live audio input. For each voice, the R3 provides two oscillators. Oscillator 1 (OSC1) gives you a choice of seven waveforms including sawtooth, pulse, formant, noise, and DWGS, as well as allowing you to select an external audio source connected to the AUDIO INPUT 1 and 2 jacks. To enhance the basic analog synthesizer waveforms such as the sawtooth, pulse and triangle waves, you can apply cross modulation, pulse-width modulation, unison voice-thickening, or even VPM (Variable Phase Modulation).Oscillator 2 (OSC2) gives you a choice of four waveforms such as sawtooth and sine, and can also be used as a modulation oscillator to apply sync modulation, ring modulation or a combination of the two for distinctively analog synthesizer sounds. The noise generator (NOISE) produces white noise, and provides a useful way to create breath noise for wind instrument sounds, or to produce evocative sound effects. The sawtooth wave and pulse wave use the same basic low-aliasing design as the AL-1 Analog Synthesizer found in Korg's flagship OASYS synthesizer.Two filters with selectable routingThe R3 features a dual filter structure that can be configured in series, parallel or an individual structure allowing each oscillator to have its own dedicated filter. Filter 1 is a multi-mode resonant design that lets you continuously vary between various low-pass, high-pass and band reject characteristics. Filter 2 has a switchable, multi-mode resonant design that also includes comb filtering, which can be made to feed back in order to boost multiple series of overtones, giving you amazing potential for generating unique tonal changes.Amp section with a Drive/Waveshaping circuitThe Drive circuit lets you create the subtle yet distinctive distortion typical of an analog synthesizer, or generate new overtones by deeply overdriving the sound. The Waveshaping circuit gives you twelve types of transformation including hard clipping, and can be used as a decimator to produce typically digital roughness by converting the sampling frequency. It can even be used as a sub-oscillator, opening up new sound-making possibilities. The Drive/Waveshaping circuit can be placed either before the amp section or immediately before Filter 1 to give you different nuances of sound. With additional |
