APEXAdaptive Limiter
Push the limits of your audio even further
The new APEX of Adaptive Limiting
CEDAR Audio invented the modern Adaptive Limiter.
APEX is built on CEDAR's pioneering Emmy® winning technology and gives engineers precise control over their audio, enabling them to increase the apparent loudness whilst preserving transparency, soundstage and depth.
Conventional limiters control the loudness of signals by suppressing peak amplitudes when they would otherwise exceed user-defined thresholds. Unlike these, CEDAR's Adaptive Limiters use a unique adaptive algorithm that calculates continuingly varying EQ profiles for each audio channel. These constrain the amplitude of the output while retaining the integrity of the input signal.
Push your sound. Push the limits.
Adaptive Spectral Limiting
At the heart of APEX lies CEDAR’s Spectral Limiting algorithm, our 'secret ingredient'. Whether you want a classic single-band feel, detailed multi-frequency shaping, or innovative Adaptive Limiting... APEX delivers.
- Spectral Control enables engineers to obtain a wide range of 'colours' from richer, weightier sounds at higher settings, to brighter or smoother sounds at lower ones.
- Temporal LF / HF Controls determine the rate at which the profile is permitted to change at low and high frequencies.
- Link Control gives engineers control of the audio soundstage, providing everything from independent channel limiting to perfectly linked gain reduction.
Greater precision. Greater transparency
APEX offers higher resolution processing at low frequencies than ever before. This enables more precise limiting, and the innovative continuously-variable Link capability gives greater control over the audio soundstage and helps users to improve the warmth and vibrancy of the audio.
By allowing a small additional latency, APEX can predict and manage transients with surgical precision. The result?
- Smoother, more transparent limiting
- Enhanced transient clarity
- More consistent loudness without pumping or distortion
Effortless Loudness Control
Reach professional loudness targets — cleanly and confidently.
- Gain – Drive your signal for maximum loudness before limiting.
- Ceiling – Set your absolute output level (e.g., -1 dBFS) for platform compliance and clipping protection.
- Oversampling – Detect and control intersample peaks with high accuracy.
- True Peak - With oversampling enabled, APEX becomes a 'True Peak' limiter.
- Quantisation – Choose your output bit depth and apply refined noise shaping for pristine delivery.
