    Dynamics Expander

  • Original language description

    The Dynamics Expander application serves for audio signal dynamics increasing. Under several circumstances the recordings created with too high compression ratio can be processed in order the better performance was gained. The application can process 16bit two channel PCM encoded wav files with the bitrate of 44.1 kHz. In order the intermodulation effect was supressed the processed frequency range is divided into 4 sub ranges with the boundaries predefined subjectively on the basis of perception of thebasses, vocal band, upper midrange and high end. At the frequency range sub-sectioning, software IIR filters are implemented. Because the separated processing can result in changing of the sound colour, the bands are backward mixed with adjustable mixing ratio. This can be also done automatically by evaluating the average energy of the signal in each bands and comparing it to the energy of the processed signal separately for each of the bands.

  • Technical parameters

    Možnost nastavení expanze dynamiky audiosignálu ve 4 různých frekvenčních pásmech s jejich nezávislým směšováním, nastavením prahu a strmosti a časů náběhu a doběhu

  • Economical parameters

    Vytvořený SW poslouží jako náhrada za komplexní hardwarové zařízení s tím, že náklady na pořízení SW jsou výrazně nižší než náklady na pořízení odpovídajícího HW.
