A clear and stable audio system starts with a clean signal. A signal processor helps control noise, balance vocal tones, and optimize recording, online meetings, and livestream quality at any scale.
What is an Audio Processor?
An Audio Processor is a device responsible for refining, cleaning, and optimizing audio signals before sending them to a mixer, speakers, or recording software. This ensures clear, low-noise sound while maintaining natural dynamics.
Popular Types of Audio Processors
For Recording Studios & Content Production
Used to optimize vocal, instrument, and recording signals.
- Channel strip / Preamp adds tonal color, basic compression, and cleans signals.
- Interfaces with DSP handle real-time processing with zero latency.
- Compressor - De-esser stabilizes volume and removes sibilance.
Example: Behringer MIC2200 V2 enhances vocals for podcasts or voice-over recordings.
For Conference & Online Meetings
Focus on clarity and reducing room echo.
- AEC - Acoustic Echo Cancellation ensures echo-free meetings.
- Noise Reduction minimizes background sounds like fans or air conditioning.
- Auto mixer balances multiple microphones simultaneously.
For Live Streaming & Small Events
Ensures stable sound without distortion during live broadcasts.
- DSP handles EQ, Compressor, and Limiter in one device.
- Speaker Processor protects the system and prevents clipping.
- Compact digital mixer for streamers, MCs, and acoustic performers.
Example: Klark Teknik DM8000 is ideal for small events, optimizing spaces with echo.
