Audacity Tips and Tricks


I'm going to collect some 'reciepies' here for more complicated effects to do in Audacity.



Censor Bleep

  • Select the part of the audio that you want to change or "bleep out"
  • Silence that section first, kill the wave
  • Generate >> Tone..
    • Waveform: Sine
    • Frequency/Hz: 1000
    • Amplitude(0-1): 0.5


Echos

  • Click here for a wiki with several different echo settings.
  • Scroll down that page and select the effect you want, also select your audio to change.
  • The effect we are using GVerb, use the settings given on the linked page.


Robot Voice

  • Select the part of the audio that you want to change
  • Effects >> Delay
    • Decay amount: 10
    • Delay time: .0045
    • Number of echos: 30
  • Repeat this delay (Effects >> Repeat Delay) 3-5 times.
  • Change the pitch higher or lower for the kind of robot you want
  • Add Bass Boost to finish the effect


Telephone Distortion

  • Select the part of the audio that you want to change
  • Effects >> FFT Filter.
    This is a difficult to explain. We need to draw a shape on this graph. Move the whole line to the bottom, then we need the graph to plateau - go the highest possible- at about 300 and about 2300 Hz. It should look something like _/TTT\_______ that but without the letter T.


Demonic

  • Have the audio on a track by itself.
  • Duplicate the original.
  • On the new track only change the pitch (Effects >> Change Pitch) find Semitones(half-steps) and enter in "-1".
  • Duplicate the original again.
  • Change the pitch of the third track to -5 semitones.
  • Add bass boost to the third track (-5 pitch track).
  • Increase the gain (Gain: +3dB) on the -5 pitch track.
  • Add an echo to the -1 pitch track (Effects >> Echo)
    • Delay time: .1
    • Delay Factor: .6
  • GVerb the -1 pitch track (Effects >> GVerb) use the default settings.


The Voice of God

  • Select the audio you want to change.
  • Add and echo with a delay time of 0.12 and factor of 0.4
  • Add another echo with a delay of 0.05 and a factor of 0.4.
  • Add effect- Change Speed, select somewhere between -10 and -20 percent.


Advanced

You need Audacity 1.3 (beta) For all of these


Auto-tune

  • First of all you need to have a recording that has a melody- it doesnt work well with flat talking (from my experiments so far).
  • Also- you must be using Audacity 1.3(Beta), it does not seem to work with version 1.2
  • Autotune is a plugin that you can download and let Audacity get extra features. Download here. Download the first or second item. The '.gll' file you downloaded must be given to Audacity to work, copy the file and paste it at C:\ -- Program Files -- Audacity -- Plugins.
  • Load up Audacity (or close and re-open) You should see GSnap in the list of possible effects.
  • Load up your vocals or whatever song you want to alter and select the part of the audio you want to change
  • Select the GSnap effect and use these settings
    • Min Freq: 40Hz
    • Max Freq: 200
    • Gate: -80dB
    • Speed: 2
    • Threshhold: 100cents
    • Amount: 100%
    • Attack: 1ms
    • Release: 4ms
    • Pitch Bend: 0 cents
    • Vibrato: 0cents
    • Vib Speed: 1.0Hz
    • Calibrate: 440Hz
    • Click on "Configure" or "Set Scale" and choose C# and Major
  • Test your results, undo, change settings and redo as you need to get what you are looking for
  • Credit goes to the many youtubers who have tutorials on this effect


Vocoder-Basic Robot

  • You will have to record your voice correctly for this to work. Speak in stacatto, use (or dont use) inflection, modulate your voice the right way.
  • You need your voice in a track by itself as the left channel (you can do all that by clicking the down arrow by your track name)
  • You need another track exactly the same length of pure white noise - right track.
  • Combine the two tracks together. (Make Stereo)
  • Now go to Effects >> Vocoader
  • Use the default setting first as a test.
    • Distance: 20.0
    • Output choice:Both
    • Number of bands: 40
    • Amp of original audio: 100
    • Amp of white noise: 0
    • Amp of Radar Needles: 0
    • Freq of Radar Needles: 30.0
  • The higher the number of bands the more natural your voice will sound, the lower the bands, the more robotic.
