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. ## Key features - Wi-Fi amplifier connection - Real-time channel tuning - 15-band parametric EQ - Advanced crossover filters - Sub-millisecond delay adjustment - FIR filter toolkit - Preset saving and sharing ## Frequently asked questions about AirDSP by Acoustas ### What can I control with AirDSP?

Select your amplifier in REW's EQ panel and its auto EQ works inside your amp's real limits - filters transfer to the app with nothing to adjust. - Low Pass Q and High Pass Q now stop at Q = 1.00, matching the REW entry exactly - Delay snaps to whole samples: the number you read is the delay that plays (7.15 mm per step at 48 kHz) - Chart CSV export lands exactly on REW's frequency grid, no accumulating drift - First-order filters no longer show a Q that does nothing - Small fixes: confirmation button colors, and the Check permissions button no longer appears on desktop ### 1.2.14 — 2026-08-07 An accuracy update: the response chart now shows exactly what your amplifier does, REW import got smarter and more honest, and there are four new EQ band types. • Response curves are now computed the same way your amplifier computes them, at your profile's sample rate. EQ bands, crossovers, and Bessel filters all draw precisely where the hardware puts them. • REW filter import supports more filter types, including adjustable-Q shelves (LS Q, HS Q), all-pass filters, and low-pass and high-pass filters. If anything in your file cannot be transferred, you now see exactly what and why before anything is committed. • Four new EQ band types: Low Pass and High Pass, 1st order or 2nd order with adjustable Q. Build an acoustic target with gentle roll-offs right next to your EQ corrections and see the combined result on the chart. • Chart CSV export now uses a fixed 1/48-octave frequency grid anchored at 1 kHz, and includes the FIR response. • Back by popular demand: the deselect-all X returns to the Channels header for faster tuning, alongside Reset. ### 1.2.13 — 2026-06-17 A tuning-workflow update: faster muting and soloing, a cleaner Channels panel, and a one-tap channel reset. • Solo and Mute in the Channels header. Select the channels you want, tap Solo to hear them on their own, then tap again to bring your full mix back exactly as it was. Mute works the same way. • A cleaner Channels header. The title sits on its own row with a single control bar (copy, reset, mute, solo), and the larger controls now match the desktop app. • Reset a channel from the header. Return the selected channels to factory defaults in one step, after a quick confirm. It clears gain, delay, routing, mute, crossovers, FIR, the 15-band EQ, and the channel name. This also fixes Reset Channel in the editor, which used to leave the EQ untouched. • Easier group editing. Long-press a group to update it to your current channel selection. • Presets remember exactly what you hear. Saving while soloed captures the live muted state, and loading a different preset clears solo cleanly. Thanks for tuning with AirDSP. ### 1.2.12 — 2026-06-14 This update smooths out the moments when your amplifier is not nearby, and refines the look of the tuning controls. AWAY FROM YOUR AMP Open AirDSP somewhere your amplifier is not on the network and it now takes you to the device list within a few seconds instead of holding on a "Reconnecting" screen. Open it again soon after and it skips the wait entirely. When your amp is on the network, it still opens straight to it. ADDING YOUR FIRST DEVICE The device list now shows an Add Device button whenever it's empty, so first-time setup can start right away instead of waiting out a scan. A MORE CONSISTENT LOOK Small visual refinements across the tuning screen: the fine-tuner, the filter and slope menus, and the FIR controls now share a cleaner, brand-consistent style. Plus the big speed improvements from our last update: AirDSP reconnects to your amp almost instantly, switches presets in a blink, and loads FIR filters in seconds. Thanks for tuning with AirDSP. ### 1.2.11 — 2026-06-12 This update is all about speed. Opening the app, switching presets, and loading FIR filters are all dramatically faster. YOUR AMP IS THERE THE MOMENT YOU OPEN THE APP AirDSP now remembers your amplifiers and reconnects to them directly instead of rescanning the network every time. Opening the app takes you straight back to the device you were using, usually in well under a second. The "Scanning for devices" wait is gone from everyday use, and the connection now recovers on its own after Wi-Fi hiccups, network changes, or a long stay in the background. PRESET SWITCHING IS NEARLY INSTANT Switching between presets that share the same FIR filter now takes about a tenth of a second, fast enough for true A/B listening. Switching between FIR and non-FIR presets completes in under a second, in both directions. A preset now counts as loaded the moment you can hear it, with verification finishing quietly in the background. FIR FILTERS LOAD IN A FRACTION OF THE TIME Applying a FIR filter now takes about 2 seconds instead of 5 to 7. If the connection drops mid-apply, AirDSP automatically picks up where it left off when the amp comes back. A new indicator in the FIR Vault shows exactly which channels a filter will apply to. CLEANER AUDIO WHILE YOU MAKE CHANGES Filter transitions now ride a brief, gentle volume dip, which removes the pops you could previously hear when switching FIR presets. Also fixed a rare case where a freshly loaded preset's FIR filter could be silently inactive until reapplied. POLISH AND FIXES Smoother opening animation, the active preset's highlight persists across restarts, refined faders and controls, better contrast in the crossover and FIR builder sections, and a fix for bass tone settings occasionally not reloading with a preset. Thanks for tuning with AirDSP. ## Apps similar to AirDSP by Acoustas | App | Rating | Price | Category | | --- | --- | --- | --- | | [Podcast Party](https://appshunter.io/ios/app/podcast-party/id6470649657) | — | Free | Entertainment | | [Midix customers app](https://appshunter.io/ios/app/midix-customers-app/id6749151792) | — | Free | Entertainment | | [Joe's Scanner](https://appshunter.io/ios/app/joes-scanner/id6758413482) | 3.5 (2) | Free | Entertainment | | [Dream Whisperer](https://appshunter.io/ios/app/dream-whisperer/id6547866253) | — | Free | Entertainment | | [JPlayer](https://appshunter.io/ios/app/jplayer/id6749754588) | — | Free | Entertainment | | [AD DSP-AT](https://appshunter.io/ios/app/ad-dsp-at/id1503273740) | 2.3 (6) | Free | Entertainment | ## Related topics [amp](https://appshunter.io/ios/topics/amp) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
