Ehren.DSP

Audio DSP software for real-time audio processing and system tuning

Developed by Pavel Smokotnin, the creator of Open Sound Meter

Presented at ISE 2026 · Open early access onboarding

Available on AppStore

Independent from
audio system architecture

Runs as a standalone DSP server
Processing workflow stays the same across different setups
Easily integrated with AoIP networks:
  • Dante®
  • Ravenna®
  • Milan®
  • AVB
  • Analog and digital IO-cards

Low-latency

Ehren.DSP is designed to work where delay matters
Capable to work with low latency drivers with latency 16 samples or even lower, suitable for real-time tuning, calibration and live shows

Integrated with
Open Sound Meter

Precalculated equalisation and filters from Open Sound Meter can be transferred directly into Ehren.DSP Creates a continuous workflow from measurement to processing
