Application Walkthrough: Set up Your Perfect Sound
Watch this video to see how to configure your DSP chain, and start streaming.
System-Wide DSP Capabilities
Dynamic Equalization
Apply 10-band or custom parametric EQ filters in real-time. Use intelligent tracking to automatically switch presets based on album or genre metadata.
Precision Output
Maintain signal integrity with configurable Headroom and advanced noise-shaping Dithering (T-PDF, etc.) before final output. Essential for down-conversion.
Universal Output
Stream processed audio to local DACs, AirPlay, DLNA/UPnP, and dedicated ANP Nodes, all managed through one cohesive interface.
The AAEQ Node Protocol: Jitter-Free Stream
ANP is a purpose-built, low-latency, secure network audio protocol that ensures bit-perfect transfer and absolute clock synchronization for ultimate audio quality.
Micro-PLL Clock Synchronization
Uses fine-grained drift telemetry (PPM) to adjust the sender's rate, locking the stream to the DAC's local clock for true jitter elimination (Target: $< 5\text{ ppm}$).
Bit-Perfect Verification & SRTP Security
Guarantees data integrity with per-window CRC32 checksums. Streams are encrypted using mandatory SRTP with AES-GCM (New in v0.3).
DSP & Convolution Transfer
Transfers the full DSP state (EQ, Dithering) to capable Nodes, enabling Convolution Filter (Room Correction IRs) application directly at the playback endpoint.
Multi-Room PTP Sync & DSD
Supports sample-accurate gapless playback and uses IEEE-1588 (PTP) for microsecond-accurate multi-endpoint synchronization. Fully supports native DSD/DoP formats.
