Multi-instance broadcast processing

Make every stream sound like a major broadcast signal.

Give every MultiEncoder output and every incoming stream its own purpose-built audio processor. Control level, density, loudness, bass and peaks independently—so each signal sounds right for exactly where it is going.

The sound is part of the brand

A stream is not truly broadcast-ready until it sounds broadcast-ready.

Listeners notice unstable levels, weak voices, uncontrolled bass and aggressive peaks immediately. CLOSE Audio Processor shapes every signal into a consistent, confident and competitive listening experience—before it reaches the audience.

ConsistentCorrect changing levels before they distract or fatigue listeners. PowerfulAdd controlled density and presence without relying on simple volume gain. ProtectedMaintain final peak control and appropriate streaming headroom.

Beyond one expensive box

One dedicated processor for every signal—without a rack full of hardware.

Traditional broadcast operations often require another physical processor every time a separately tuned output is needed. The CLOSE software architecture creates independent processing instances inside the complete streaming workflow.

Every output. Every input. Its own sonic purpose.

The same program does not need to sound identical everywhere—and not every incoming source arrives properly controlled.

The broadcast sound chain

Four stages. One controlled signature.

Each processor instance combines level control, tonal weight, density, loudness and final protection in an ordered real-time chain.

Correct firstStabilize uneven sources before dynamics processing.
Shape deliberatelyAdd low-end body and density according to the format.
Protect the destinationFinish with controlled headroom and peak safety.

INPUT CONTROL

AGC / Leveler

Corrects low and uneven sources before compression.

STABILIZED

TONAL WEIGHT

Bass Enhancer

Adds controlled low-end body before the final dynamics stages.

ENHANCED

DENSITY + POWER

Compressor / Loudness

Shapes consistency, impact and perceived on-air power.

Limiter

Controls peaks and preserves streaming headroom.

PROTECTED

Start with the sound you need

Broadcast profiles that operators can understand.

Choose the desired behavior, then refine the amount of level correction, loudness, density and protection without exposing the internal processing complexity.

CLEAN

Natural correction

For sources that are already controlled and need transparency, stability and protection.

High-performance software. Broadcast-grade engineering.

Built to process multiple live signals in real time.

The engine is designed for continuous streaming operations where audio cannot wait. Each active instance runs its own processing chain while remaining part of the unified CLOSE and MultiEncoder environment.
