AirDSP by Acoustas

iOS Universel / Divertissement

AirDSP by Acoustas is the control and tuning app for Acoustas DSP amplifiers. Connect over Wi-Fi, tune every channel in real time, and hear your changes the instant you make them.

The app was previously called the Acoustas App. Same app, same devices. New name. New functionality.

CONTROL
Power and standby, source select, master volume with 1 dB resolution, per-channel mute, full channel routing, and channel groups for multi-way setups.

TUNE
- 15-band parametric equalizer, tuning all the way down to 10 Hz
- 0.25 dB EQ resolution with a fine tuner for dialing any single band
- Peaking, low shelf, high shelf, and biquad filter types
- Crossovers: Butterworth, Linkwitz-Riley, Bessel, 6 to 48 dB per octave
- Sub-millisecond delay in milliseconds, inches, feet, millimeters, or meters
- Per-channel fine-tune gain, independent of master volume

FIR VAULT (linear-phase filter toolkit)
- Linear Phase Linkwitz-Riley: classic LR shapes with zero phase distortion
- Invisible Linear Phase: the cleanest possible transitions between drivers
- Nt-X Pro Linear Phase: the most advanced linear-phase option in AirDSP
- Phase Linearizer: correct the phase response of any filter chain

PRESETS AND AMP STATE
- Save presets to your amp and A/B compare them instantly
- Export any preset as a .acp file to share, back up, or move to another amp
- Export an entire amp state as a .acs file, with every preset, every FIR, and all routing captured in one file

FIRMWARE OVER THE AIR
Firmware updates now land directly through the app. No cables, no extra tools.

PROVISIONING
Add a new Acoustas amp to your Wi-Fi network in seconds, over Bluetooth or with manual Wi-Fi entry. No separate setup app.

PRIVACY
Preset and amp state files never contain Wi-Fi credentials, Bluetooth pairing data, or device serial numbers. They are safe to share.

AirDSP is developed by Lava Lab LLC for Acoustas LLC amplifiers and audio devices.

Quoi de neuf dans la dernière version ?

A summer release that ties off a months-long design pass and adds the most-requested tuning tool yet.

ALL-PASS FILTERS IN THE 15-BAND EQ

You can now place 1st- and 2nd-order all-pass filters on any of the 15 EQ bands. All-pass filters don't change the frequency response. They rotate phase around a chosen frequency. That's the tool you reach for when you want a tweeter and a midrange to line up cleanly through their crossover, or to clean up the timing of a stack that was never built to be coherent.

• AP1 rotates 180° across its frequency with the slope of a 1st-order pole. Set the frequency and you're done.
• AP2 rotates 360° and is the workhorse for crossover phase alignment. A Q of 0.5 lines up with an LR2 crossover. A Q of 0.707 lines up with the more common LR4.

AP bands show up in the EQ picker alongside peaking and shelf bands. The chart draws their phase response as a soft wash in the channel color so you can see exactly what each filter is doing, and a dotted band trace marks the rotation point. Magnitude stays exactly where you left it.

ROOM EQ WIZARD IMPORTS NOW INCLUDE SHELVES

The Room EQ Wizard importer now accepts low-shelf and high-shelf filters in addition to peaking filters. The typical "Match response to target" output, which often emits a low shelf and a high shelf alongside its peaks, now lands in AirDSP exactly the way REW measured it. No more hand-rebuilding shelves after every import.

Filter types AirDSP cannot store, such as all-pass or modal bands, are skipped with a note in the preview so you always know what made it across and what didn't.

The 15-band EQ also now exports each band with its actual filter type, so files written by AirDSP can be read directly by Equalizer APO, Music Assistant, CamillaDSP, and other parametric EQs that read REW's generic text format.

A NEW LOOK

This release is the destination of a design pass that started in the winter, drawn from the iconic look of vintage Japanese hi-fi gear. New teal accent color throughout. Lit faders. A recessed tone-fader cavity with overhead glow. An aluminum-cap power switch you drag to slide. Vintage gain and delay sliders. Redrawn LED meters. Rebuilt device cards. Every screen has been retouched to feel like a piece of real audio gear instead of a software panel. The static wordmark on launch has been replaced with a short, hypnotic video that plays as AirDSP opens.

FIRMWARE v1.8.0

Every device updates to firmware v1.8.0 with this release. Two notable changes:

• Your amp now works straight out of the box, even before you connect it to Wi-Fi. Plug in, hit power, music plays.
• Overload protection now resets cleanly after a fault clears, so you no longer have to power-cycle the amp to get audio back.

IMPROVEMENTS AND FIXES

• More reliable device discovery, with automatic recovery if a scan stalls or the device list gets stuck.
• The fine-tuner's Reset link now closes the panel before showing the confirm dialog, so the confirm is never hidden behind it.
• Switching a band type back to peaking now restores the previous gain instead of zeroing it.
• Preset loads now clear stale FIR state cleanly per channel, fixing rare cases where a fresh preset would briefly inherit the previous one's FIR config.
• Status-readout copy, and dozens of smaller polish touches across the app.
