Use the Special > Distortion effect to simulate blown car speakers, muffled microphones, or overdriven amplifiers.
Special effects require mono or stereo audio; they do not support 5.1 surround.
Positive and Negative graphs
Specify separate distortion curves for positive and negative sample values. The horizontal ruler (x‑axis) indicates input level in decibels; the vertical ruler (y‑axis) indicates output level. The default diagonal line depicts an undistorted signal, with a one‑to‑one relationship between input and output values.
Click and drag to create and adjust points on the graphs. Drag points off a graph to remove them.
To copy one graph to another, click the arrow buttons between them.
Creates curved transitions between control points, sometimes producing a more natural distortion than the default linear transitions.
Determines how quickly distortion reacts to changes in input levels. Level measurements are based on low-frequency content, creating softer, more musical distortion.
Changes the amplitude scales of the graphs from logarithmic decibels to normalized values.
Post-filter DC Offset
Compensates for any sample offset introduced by distortion processing. To understand this concept, see Correct DC offset. Such offsets can cause audible pops and clicks when edited.
Guitar Suite effect
The Special > Guitar Suite effect applies a series of processors that optimize and alter the sound of guitar tracks. The Compressor stage reduces dynamic range, producing a tighter sound with greater impact. Filter, Distortion, and Box Modeler stages simulate common effects that guitarists use to create expressive, artistic performances.
Apply the Guitar Suite to vocals, drums, or other audio to create textured effects.
Reduces dynamic range to maintain consistent amplitude and help guitar tracks stand out in a mix.
Simulates guitar filters ranging from resonators to talk boxes. Choose an option from this menu, and then set options below:
Adds a sonic edge often heard in guitar solos. To change the distortion character, choose an option from the Type menu.
Simulates various amplifier and speaker combinations that guitarists use to create unique tones.
Mastering describes the complete process of optimizing audio files for a particular medium, such as radio, video, CD, or the web. In Adobe Audition, you can quickly master audio with the Special > Mastering effect.
Before mastering audio, consider the requirements of the destination medium. If the destination is the web, for example, the file will likely be played over computer speakers that poorly reproduce bass sounds. To compensate, you can boost bass frequencies during the equalization stage of the mastering process.
Drag control points in the graph to visually adjust the settings below.
Exaggerates high-frequency harmonics, adding crispness and clarity. Mode options include Retro for light distortion, Tape for bright tone, and Tube for quick, dynamic response. Drag the Amount slider to adjust the level of processing.
Adjusts the stereo image (disabled for mono audio). Drag the Width slider to the left to narrow the image and increase central focus. Drag the slider to the right to expand the image and enhance spatial placement of individual sounds.
Applies a limiter that reduces dynamic range, boosting perceived levels. A setting of 0% reflects original levels; 100% applies maximum limiting.
Determines output levels after processing. For example, to compensate for EQ adjustments that reduce overall level, boost the output gain.
Vocal Enhancer effect
The Special > Vocal Enhancer effect quickly improves the quality of voice-over recordings. The Male and Female modes automatically reduce sibilance and plosives, as well as microphone handling noise such as low rumbles. Those modes also apply microphone modeling and compression to give vocals a characteristic radio sound. The Music mode optimizes soundtracks so they better complement a voice-over.
