Documentation
Deployment guideLoad into RootlessJamesDSP
Chain: DDC (identity) → Convolver (IRS) → EEL2 → Output. Set the host sample rate to 48 kHz and load each file into its slot.
Tonal correction lives only in the IRS. Never load the same EQ in both the VDC and the convolver: it applies twice.
Evidence & limitationsWhat has and has not been verified
Checks ran offline (source-built JamesDSP VM on x86_64 and NumPy). Not yet run: the app, native convolver, ARM, null tests and listening tests. The IEM tuning has no measurement behind it and the speaker EEL NaN/inf test is pending a rerun.
The browser checks on this page are file checks, not RootlessJamesDSP runtime validation.
