XSCACE Studio
DSP control, intelligent room correction and a full professional calibration suite.
XSCACE Studio is the command centre for XSCACE DSP amplifiers — the Xylem series and, as of August 2026, the Root series. It discovers every device on the network, exposes the complete DSP — routing matrix, gain, delay, crossovers, parametric EQ on both inputs and outputs — and layers three intelligent systems on top: PsySculpt low extension, X-Sense room correction, and an eleven-instrument Calibration Toolkit that measures the room and writes the correction back to the amplifier in one app. Its delay measurement agrees with REW to 0.01 ms, and where a reading cannot be defended it refuses rather than reporting a number.
Live DSP Control
Connect to any Xylem on the network and the full signal chain opens up: per-channel gain and delay, four crossover modes with live curve rendering, and six bands of parametric EQ per channel. Changes hit the DSP instantly over the local network — no round trips, no cloud. Discovery is zero-configuration: amplifiers announce themselves, so there is nothing to pair and no address to type. The delay block itself is accurate to 3 µs on a commanded 5.000 ms.
Arrival-Time Measurement That Survives Wireless
Aligning speakers needs each one's arrival time at the listening position to sub-millisecond accuracy — sound moves about 34 cm per millisecond, so a 1 ms error puts a speaker a third of a metre from where it really is. A wired rig gets this from a loopback cable, where one clock drives playback and capture. Over a network there is no loopback and the receiver's clock is not yours, so XSCACE Studio rides a train of quiet pilot bursts throughout the entire measurement — including underneath the sweep — and reconstructs the receiver's real time map from them. Against REW, the reference tool in this field, it agreed to 0.01 ms.
Eleven-Instrument Calibration Toolkit
Eleven instruments: X-Sense EQ, SPL Meter, Delay, Levels, Polarity, Frequency Response, Sub Align, Transfer Function, RT60, RTA and Mic Cal. One run yields distance, level, polarity and signal-to-noise for every channel. Every measurement can export the raw microphone capture as a 16-bit WAV, so any disputed result can be dissected offline against a reference implementation.
It Refuses Rather Than Guesses
A measurement tool that returns a confident wrong number is worse than one that returns nothing. RT60 follows ISO 3382-1 practice — Lundeby truncation, a minimum 12 dB fit span, an r² ≥ 0.90 quality gate — and when a room will not support a defensible reading it says so and tells you which way to move: raise the level, or quieten the room. Every run also measures its own worst timing warp and warns above 0.5 ms, recommending a wired input for sub-millisecond work.
PsySculpt Low Extension
A per-input side-chain that synthesises harmonics of fundamentals the cabinet cannot physically reproduce, so the ear infers a fundamental that is not being played. It is not a bass boost — nothing below the driver's range is amplified, because there is nothing there to amplify. The control reads "extend down to X Hz" because it sets how deep the effect reaches rather than naming a filter, with an extension target down to 40 Hz and settings that ride along with system presets.
X-Sense Room Correction
Guided calibration in minutes: sweep measurements from up to three listening positions, corrective EQ fitted against six sound profiles, and room diagnostics. A verification pass re-measures with the EQ live and overlays before, target and after — the correction is proven, not promised.
One Number, Not Thirty-Four
Per-channel limiting built on a peak-and-RMS combo: a 34-point gain transfer curve plus five time constants. You set one value — threshold in dBFS — because that is the number printed on the driver's datasheet and therefore the one an installer actually has. The device generates the curve from it, and the app states the consequence in plain language: at −6 dBFS, output is held there and peaks above it are caught in about 2 ms. Peak and RMS detectors run in parallel and whichever asks for more reduction wins. 33 factory presets across the range ship with thresholds derived from each speaker model's real power handling; an amplifier lists the presets matching its own channel count.
Full Demo Mode, No Hardware
A complete demonstration amplifier runs locally with populated measurements, so every chart and the full report render on a bare machine in a showroom with nothing connected. Every surface showing that data says plainly what it is — a banner above the results and a block at the top of the report — because synthesised data that reads like a measurement eventually gets filed as one.

What platforms does XSCACE Studio run on?
macOS, Windows, and as an in-room web app served directly from every Xylem amplifier — no separate install needed to reach the local dashboard.
Is XSCACE Studio free?
Yes, XSCACE Studio is free for macOS and Windows.
What hardware does it work with?
Every XSCACE Xylem DSP amplifier. It also has a standalone mode that can measure and report on third-party systems via AirPlay.
Does it need an internet connection?
No. It connects directly to the Xylem amplifier over your local network — no cloud, no round trips.
What is the Calibration Toolkit?
Eleven professional measurement instruments built into the app — X-Sense EQ, SPL Meter, Delay, Levels, Polarity, Frequency Response, Sub Align, Transfer Function, RT60, RTA and Mic Cal — SPL, delay/levels/polarity, frequency response, THD, sub alignment, transfer function, RT60, RTA, and branded PDF reporting.
Can I use my own measurement microphone?
Yes. The toolkit supports UMIK-style calibration file import (frequency and sensitivity) for fixed-output USB measurement microphones.
What is audio calibration software?
Audio calibration software measures how a speaker system actually performs in a room — SPL, frequency response, time alignment and reverberation — then uses that measured data to correct the DSP. XSCACE Studio does this with an 11-instrument toolkit built directly into the amplifier control app, so no separate measurement software is needed.
Can I use it as RT60 measurement software?
Yes. The Calibration Toolkit includes an impulse-triggered RT60 measurement (ISO 3382-aligned) with energy-time curve and spectral decay waterfall views, alongside a 31-band RTA with NC background-noise rating.
How is this different from REW?
REW is free, general-purpose measurement software that works with any amplifier but writes nothing back to the DSP for you — you measure in REW, then manually re-enter corrections elsewhere. XSCACE Studio's toolkit measures AND writes the correction straight to the Xylem amplifier's DSP in the same app, with a closed-loop re-measurement to confirm the fix actually worked. It's a narrower tool — XSCACE amplifiers only — but it removes the export/re-enter step entirely.
How accurate is the delay measurement?
Validated against REW, the reference tool in this field. Measuring the same system, a wired reference gave an inter-channel difference of +0.551 ms and XSCACE Studio measured +0.56 ms — agreement to 0.01 ms. Separately, the Xylem DSP's own delay block is accurate to 3 µs on a commanded 5.000 ms.
Is it as accurate over a wireless connection as over a cable?
Accuracy is proven either way; precision over wireless is limited by the receiver, and the app is candid about it. A wireless receiver re-buffers between plays and applies its own timing corrections mid-stream, so every run measures its own worst time warp and warns you when it exceeds 0.5 ms, recommending a wired input for sub-millisecond work. It tells you when to distrust it rather than presenting a confident number it cannot stand behind.
Why does it ask me to play a test tone before measuring?
Because a connection that reports success is not proof of sound. Compatibility testing found that licensed wireless receivers will accept a stream, report a healthy session, and silently discard the audio unless the sender meets the full specification. The ♪ test button beside the output picker exists so that no measurement is ever taken against silence.
How does it measure arrival time without a loopback cable?
A wired rig aligns speakers using a loopback, where one clock drives both playback and capture. Over a network there is no loopback and the receiver's clock is not yours. XSCACE Studio rides a train of quiet pilot bursts on a fixed carrier channel throughout the whole measurement — including underneath the sweep — and fits a line across them to reconstruct the receiver's real time map. Sound travels roughly 34 cm per millisecond, so a 1 ms error would put a speaker a third of a metre from where it actually is.
What happens if the room is too noisy to measure?
It refuses, rather than reporting a number it cannot defend. RT60 follows ISO 3382-1 practice — Lundeby truncation, a minimum 12 dB fit span and an r² ≥ 0.90 quality gate — and when a measurement does not meet them the failure message tells you which way to move: raise the level, or quieten the room.
Can I verify the app's own working?
Yes. Any measurement can export the raw microphone capture as a 16-bit WAV, so a disputed result can be dissected offline against any reference implementation you like. Several corrections during the app's development came from exactly that.
What do I have to set on the limiter?
One number: threshold in dBFS. That is the figure printed on the driver's datasheet, so it is the one an installer actually has to hand. The 34-point gain transfer curve is generated on the device from it, with peak and RMS detectors running in parallel and whichever asks for more reduction winning. 33 factory presets across the range ship with thresholds derived from each speaker model's real power handling, and an amplifier lists the presets matching its own channel count.
What does PsySculpt actually do?
It synthesises harmonics of fundamentals the cabinet cannot physically reproduce, so the ear infers a fundamental that is not being played. It is not a bass boost — nothing below the driver's range is being amplified, because there is nothing down there to amplify. That is why the control reads "extend down to X Hz": it sets how deep the effect reaches rather than naming a filter.
