Audio Effects

Equalization is a process of normalizing the frequency response to be as flat as possible to reflect the original reproduction of the sound. Equalization is necessary for several closed environments, where reflections or speaker limitations influence sound quality. With the ability to both boost and cut several frequency bands, it is possible to neutralize external factors for a natural sounding audio.

The equalizer can also be used to simulate a music type which is rich in specific components. The several presets available with the Graphic equalizer serve this purpose.

Parametric equalizers are multi-band variable equalizers which allow users to control the parameters of sounds.

The Bass and Treble controls allow the user to finely tune the most affected audio component, without complexity of using an equalizer. Bass or Treble can be boosted or cut, to neutralize speaker or headphone responses.

Stereo widening causes a sound to be expanded beyond two speakers. If your stereo speakers are located close, such as in case of cell phones and tablets, a stereo expansion can create a more spacious environment. The implementation from Picus Tech allows this effect, without compromising audio quality.

Reverberation is an effect, where thousands of echoes are retained in the audio after the original sound has been played. Picus Tech has created a high-performance reverberating solution with easily controllable knobs to tune different environments. The reverberation effects allow audio to be rendered in different environments like concert halls, auditoriums creating a rich listening experience.

Reverberation algorithms normally consume significant computational resources and are complex to implement. However, Picus Tech implementation is a low MIPs implementation, ensuring, that it can be available for even very low CPU requirements. With most important parameters readily tuneable, any desired response can be readily simulated.
