ROOTLESSJAMESDSP · 48 KHZ · TWO DEVICE PROFILES
Purpose-built DSP correction for the KZ EDX Pro and Redmi 12 speaker. Download established releases, inspect the full asset library and audition an experimental browser preview.
Designed & tuned by Noushad M. · Offline file verification · Device testing status disclosed
The v5-HD IRS is a four-channel true-stereo matrix. The EEL2 header refers to an earlier Ultra IRS/VDC pairing, so validate that stage independently before deployment.
The V6 three-file set is the established Redmi 12 profile. The limiter runs after the IRS and does not add tonal EQ.
HyperAudio publishes two established three-file profiles. The KZ EDX Pro uses the v5-HD release; the Redmi 12 speaker uses the V6 release. The selected files are organized as VDC → IRS → EEL2 profiles. Review each file’s pairing notes before enabling the complete chain.
Keep releases paired. Load the VDC, IRS and EEL2 files from the same release folder. Do not combine files across versions or stack an optional IRS on top of the core IRS.

Every retained release is indexed from the actual files. Sizes and SHA-256 hashes are generated at build time. The established profiles are shown first; historical and experimental releases remain grouped below.
Compare the selected profile's unprocessed source (A) against its browser-rendered VDC → IRS chain (B). The EEL2 stage is not emulated. This preview is not RootlessJamesDSP and is not an acoustic measurement.
Selected profile follows the Established Profiles selector.
Preview limits. Experimental browser DSP only; browser and output-device resampling differ from the app. No calibration, native DSP equivalence or device validation is implied. Use the IEM preview only with the KZ EDX Pro; the speaker preview is meaningful only when opened on the Redmi 12 itself.
Signal handling. A common −12 dB safety pad is applied. B is RMS level-matched against the first five seconds of the source, with the correction bounded to −12…+3 dB. A/B switching cross-fades briefly. The 4-channel IRS uses the browser's native true-stereo convolver mapping; left-only and right-only test tones help check channel routing.
Not emulated. EEL2, limiter behavior, app resampling, the Android audio path, calibration and acoustic room/device response.
The selected release is checked in your browser: RIFF/float32 IRS layout, finite samples, stereo or true-stereo symmetry, peak and tail levels, stable VDC biquad poles, and EEL slider structure. Peak gain and L1 are reported as diagnostics, not universal pass/fail gates.
Offline checks on both chains. Not app, ARM or device validation.
| Component | Offline / numerical | App or device | Listening |
|---|---|---|---|
| IEM VDC · v5-HD | PASS 14 sections; stable 48 kHz bank | NOT RUN | NOT RUN |
| IEM IRS · v5-HD | PASS 4-channel float32; finite and symmetric | NOT RUN | NOT RUN |
| IEM EEL2 · v5-HD | STATIC REVIEW header pairing caveat | NOT RUN | NOT RUN |
| Speaker VDC · V6 | PASS 10-section identity bank | NOT RUN | NOT RUN |
| Speaker IRS · V6 | PASS 2-channel float32; finite and symmetric | NOT RUN | NOT RUN |
| Speaker EEL2 · V6 | PASS static structure and slider parse | NOT RUN | NOT RUN |
Evidence boundary. PASS denotes static file-format, coefficient, or source-structure checks only. It does not mean native RootlessJamesDSP, ARM, device, acoustic or listening validation. No current selected profile has been marked device- or listening-validated.
Each correction is fitted against a target curve, in dB relative to 1 kHz. Both targets are custom, built offline, and not published standards. Listening results outrank the curves.
Method and principles: Raw and target curves.
addons/ holds two optional impulse responses and three EasyEffects reference presets. See the add-on guide.
bbe-sonicmax.irs +7.9 dB (left) and +9.8 dB (right); efotech-mlv-01024-true-stereo-48khz.irs +3.7 to +5.3 dB across its four channels. The project gate is 0 dB. The convolver loads one IRS at a time, so an add-on IRS replaces the tonal-correction IRS rather than adding to it. Lower the volume before trying one.
Optional impulse responses for phase and spatial experiments. Use instead of the core IRS, never alongside it.
Reference files for Night Listening, Concert Hall, and Gentle Dynamics. These cannot be loaded directly into RootlessJamesDSP; they are for manual parameter replication.
Chain: DDC (VDC) → Convolver (IRS) → EEL2 → Output. Set the host sample rate to 48 kHz. The IEM v5-HD VDC contains 14 tonal biquads; the Redmi 12 V6 VDC is identity. The IEM EEL2 header references an earlier Ultra pair and needs independent runtime verification.
The IEM v5-HD VDC and IRS both contribute to its correction chain. The Redmi 12 V6 VDC is an identity bank and its IRS provides the tonal correction. Do not add a duplicate external EQ.
The current release checks are static file and coefficient checks. Native RootlessJamesDSP execution, ARM behavior, acoustic measurements and controlled listening tests have not been performed for these selected files. The IEM v5-HD EEL2 header pairing remains a specific compatibility caveat.
The browser checks on this page are file checks, not RootlessJamesDSP runtime validation.

Verify any download with sha256sum. The build script generates assets.json from the actual files and records full SHA-256 hashes. The established IEM export points to v5-HD; the Speaker export points to V6.
