  • Page 34 The Best Performance The dynamic range processor principles developed by Junger Audio make it possible to realize dynamics processors (compressor, limiter, expander) with very high audio quality, without signal coloration, pumping or breathing, and without distortion and modulation products.
  • Page 35 THE JÜNGER AUDIO COMPRESSOR & EXPANDER PRINCIPLE Compression is defined as the reduction of the dynamic range of the input signal to match the dynamic range of the storage system, transmission system, and/or the listening environment. Typical approaches to this task often result in audible artifacts and lack luster performance.

  • Page 43 LEVEL MAGIC d06 d07 b46 C8007 C8046 Introduction & Reference guide To understand the principle of the new algorithm and the adjustment of LEVEL MAGIC it is necessary to keep some psychoacoustic aspects in mind 1. We do not perceive level changes if they happen in a certain period of time dependent on the absolute value of the level change.
  • Page 44 Level Magic different from previous dynamics processors? A compressor/limiter combination of a known dynamics processor by Junger Audio is always controlling the audio level in relation to the limiter threshold. In result no headroom is more existing and the signal is developed to reach a 100% output level.
  • Page 45 Independent on the leveller circuits the brickwall limiter is taking care on the peak level. For the leveller (AGC + Transient Processor) Junger Audio is using a unique combination of QP and RMS level detectors to analyze the incoming audio signal. In comparing QP and RMS measurement results we can find out how much transients are coming in.

    Software releases 3.xx are dedicated to the recently launched LevelMagic™ firmware of C8007 / d07. Since many new PCs do not have serial interfaces “on board” and CAN interface installation was sometimes tricky we decided to equip new devices with an Ethernet interface.
