To this end, after a description of the original and the derived algorithms, quantitative test are carried out using typical analyses from the Sound and Music Computing literature, such as frequency response, transfer function, and harmonic distortion. Beside testing if the domain shift from image to audio processing can bring some interesting result, this work also investigates if ADAE behaves like already-known technologies for audio manipulation and restoration. This algorithm has been inspired by research carried out in the context of image restoration: it is the adaptation of a contrast and color unsupervised equalizer for images, called Automatic Color Equalization (ACE), into the audio domain. This paper explores the behavior of an algorithm called Audio Dynamics Automatic Equalization (ADAE). The two paths are then mixed back before. The signal is then passed through the amplitude attenuator, attenuating between 20-70% for vocals and speech. By clipping asymmetrically, both odd and even harmonics are generated. Soft clipping ensures only low-order harmonics are generated. The high-frequency components are extracted and transformed non-linearly by the clipper. This consists of a 2nd-order Butterworth high-pass filter, followed by an asymmetric soft clipper. The excited path passes through the exciter block. Leaving aside the pre-amplifiers (13 and 23), the processing for excitation occurs in the exciter (No. 25) may be a loudspeaker or mag- netic tape. 1) is a monaural signal from a microphone, radio tuner or amplifier combination. Synthesis of Model The technical information disclosed in the Aural ExciterвЂ™s patent was closely referenced for modeling (refer to Fig. 1 In FAUST, a digital model of an exciter was implemented based on the original APHEX Aural Exciter. DIGITAL MODELING FAUST is a functional programming language for real- time audio signal processing, enabling generation of standalone applications and audio plugins. Exciters also find use in the communications and entertainment markets to improve speech intelligibility (Aphex 2013).

Today, digital exciter effects exist in audio editing software such as Avid Pro Tools and Apple Logic Pro. Competi- tors have created similar effects, both prior to, and af- ter the advent of the APHEX Aural Exciter (Dietz et al. This technology was patented in 1979 by Aphex Ltd., and trademarked as the Aural Exciter (Knoppel 1979), (ZГ¶lzer et al.

It has also been termed a вЂњsharpness maximizerвЂќ (Chalupper 2000), where small non-linear effects yield marked psychoacoustic effects. The exciter in- troduces a measured amount of high-frequency distortion to achieve this, occasionally employing phase shifting.

The timbre is described as having a bright, airy or sparkly feel, free of the harshness that can some- times result from equalizer treble boost. INTRODUCTION A harmonic exciter is an audio effects processor that em- phasizes certain frequencies in order to change the timbre of a sound.
