Loudspeaker DSP for Mac

Desktop DSP

Build, run, and verify a loudspeaker signal path on your Mac.

Desktop DSP combines a visual signal-flow editor, realtime processing, metering, and internal transfer-function analysis in one standalone application.

Beta: this build is not signed with an Apple Developer ID and is not notarized. macOS may block its first launch.

Audio safety: mute outputs and reduce amplifier or speaker level before opening or changing a signal path. Unexpected high levels can damage equipment and hearing.

Desktop DSP

One workspace from routing to verification

Visual Signal Flow

Route up to 16 inputs and 16 outputs, group processing into nested Subsystems, and edit the graph while DSP is running.

Loudspeaker DSP Blocks

Use FIR, peaking, shelving, low-pass and high-pass filters with Gain, Delay, polarity, and arithmetic Blocks.

Internal Analyzer

Calculate Magnitude, Phase, Impulse Response, and Harmonic Distortion through the configured DSP path without a physical loopback.

Operational safeguards

Start muted, monitor levels and callback load, and stop output when the engine detects invalid audio, sustained DC, or a missed processing deadline.

Compatibility

System requirements

macOS 14.2 or later
Apple Silicon Mac
Core Audio input and output for realtime processing
44.1, 48, or 96 kHz when supported by the selected device

A Windows build is not included in the 0.14 Beta.

Safety

Protect connected equipment

Begin with Master Mute enabled and downstream amplifier levels reduced. Verify routing, filters, gain, polarity, delay, and physical output assignments before unmuting. A DSP configuration can produce unexpectedly high levels or signals that may damage loudspeakers, amplifiers, or hearing.
