AirDSP by Acoustas connects to Acoustas DSP amplifiers over Wi-Fi to put complete tuning control in your hands. Power, source, volume, tone, presets, and every advanced DSP capability are live in the app, and changes are audible the moment you make them.

Available on iPhone, iPad, Mac, and Windows. Tune from your phone, build complete profiles on a desktop, or both. Your work syncs across every device automatically.

CORE CONTROLS
- Power on/off and source selection
- Volume with 1 dB resolution
- Redesigned tone control
- Mute, route, and invert phase per channel
- Independent fine-tuned gain per channel

15-BAND EQUALIZER
- 0.25 dB precision, all the way down to 10 Hz
- Peaking, low shelf, high shelf, and biquad filter types
- Custom faders with haptic feedback on every adjustment
- Drag the dot on the graph or fine-tune any single band
- Long-press a band's gear icon to instantly reset it to flat

CROSSOVERS

FIR VAULT AND FIR BUILDER
- Linear Phase Linkwitz-Riley: classic LR shapes with zero phase distortion
- Invisible Linear Phase: the cleanest possible transitions between drivers
- NtX Pro Linear Phase: the most advanced linear-phase option in AirDSP
- Phase Linearizer: correct the phase response of any filter chain
- Sub-millisecond delay precision in milliseconds, inches, feet, millimeters, or meters

PRESETS AND AMP STATE
- Save any preset as an .acp file: EQ, FIR, crossover, delay, gain, routing, mute, volume, channel groups, and device metadata
- Save the entire amp as an .acs file: every preset on the amp plus every setting
- Share .acp and .acs files freely. No Wi-Fi credentials, Bluetooth pairing, or serial numbers are ever included

PROVISIONING AND UPDATES
- Bluetooth or manual Wi-Fi provisioning, built right in
- Over-the-air firmware updates through the app
