Release DSPi Console v1.1.5 · WeebLabs/DSPi-Console

DSPi Console v1.1.5

Everything from the v1.1.5 beta series, plus the changes since beta6. If you have been running the betas, skip to Since v1.1.5-beta6 at the end.

Crossover tab - dedicated per-output crossover filters: Linkwitz-Riley, Butterworth, and Bessel families, orders 1-8, low and high pass
Linkwitz Transform - a filter type on output channels that replaces a sealed-box driver's (f0, Q0) rolloff with a target (fp, Qp) alignment, with the implied DC boost shown so you can match a preamp cut. Edits are staged behind Apply / Revert
First-order filter types - 1st-order all-pass, low shelf, and high shelf, plus 6 dB/oct High Cut and Low Cut. Both cuts now group their 6 dB/oct and 12 dB/oct variants under one menu entry
Volume Leveller overhaul - redesigned with a live gain-transfer curve and per-channel detector / apply masks for full multichannel control
Multichannel Loudness Compensation - apply loudness compensation to any selected set of output channels
Multichannel Crossfeed - crossfeed is now assignable per output pair
Band gain carries three decimals end to end, and Q exports at the precision the app holds

Stereo Upmixer - derives Centre, Ls and Rs from a stereo source, with selectable centre and surround modes, decorrelation, surround delay / filtering, and a presence control. RP2350 only
Psychoacoustic Bass - missing-fundamental bass extension, assignable per output channel, with cutoff, harmonics, drive, character and original-level controls
Test tone generator - built-in sine, noise, and sweep tones with per-channel routing

8-channel USB input - full 7.1 surround input on RP2350, with a unified channel model where inputs are first-class EQ + metering channels. The sidebar and matrix mixer adapt to the active input count
Multichannel I2S input - 2 / 4 / 6 / 8-channel I2S input (up to four stereo RX pairs), each with its own configurable serial-data pin
I2S slave mode - run the DSPi as an I2S clock slave, with the external master driving BCK / LRCLK and the sample rate auto-detected, plus lock status and clock diagnostics
Configurable I2S clock pins - unified or separate master / slave BCK + LRCLK pin pairs
ADAT output - stream all 8 main output channels as a single ADAT optical lightpipe signal. RP2350 only
ADAT input - use an 8-channel ADAT lightpipe as the input source, with its own RX pin, clock mode and lock status. RP2350 only
Four switchable S/PDIF inputs - up to four S/PDIF input instances with independent, hot-swappable RX pins and per-input enable
Hardware configuration persistence - choose whether your input and output wiring is stored on the device independently or saved with each preset
Active input channel count is read from macOS CoreAudio, so it stays correct to your selected format even with no audio playing

Wire your own physical buttons, switches, potentiometers, rotary encoders, and LEDs and bind them to firmware parameters
IR remote control - learn and bind up to 16 infrared remote buttons, with a guided learn flow and per-command naming
Loudness reference SPL and intensity are now bindable
Edits use the same Apply / Save / Revert bar as the rest of Settings, with binding menus grouped into per-family submenus
External control interfaces - drive the DSPi from an external microcontroller over UART or I2C

Save and restore a whole device configuration to a file - a complete snapshot of the device, portable between machines
Filter import / export overhaul - exported files carry every active input channel, the per-input preamp and the crossover bank, and every filter type survives a round trip intact (Q on cuts and shelves, notch, all-pass, Linkwitz Transform and per-band bypass were previously lost). Imports honour a REW or AutoEQ preamp line and report anything they could not apply

Copy and paste channels from the keyboard - Cmd+C and Cmd+V copy the selected channel's filter bank onto another channel. Copying an output also carries its crossover bank, gain, delay and mute, and pasting onto a stereo input mirrors to its partner when Link L/R is on
Link any adjacent pair of input channels, not just 1/2
Graph curve toggles moved into the sidebar channel pills
Settings reorganized into unified Inputs / Outputs pages, and the Settings window is resizable
Value fields now require Cmd to change by scrolling, so a stray scroll cannot alter a setting
Sidebar polish: brighter channel pills, one definition per channel color, dynamic spacing that follows the active input count

Multi-device correctness - commands, monitors and staged setting drafts are bound to the device they were started on, so switching or hot-plugging a DSPi mid-operation can no longer land a change on the wrong unit
Sturdier USB connection: the connect path retries instead of giving up after a single failure
Warnings before changing an external mute setting during playback, and before running ADAT output from a free-running clock
Fixes: output route preview, and a 60 ms scene rebuild stall

Save and restore a whole device configuration to a file - a complete snapshot of the device, portable between machines
A fourth S/PDIF input, following the firmware up from three
Sixteen IR remote commands per receiver, up from eight
Loudness reference SPL and intensity are now bindable from Control Surfaces
First-order (6 dB/oct) High Cut and Low Cut filter types, with both cuts now grouping their 6 dB/oct and 12 dB/oct variants under a single menu entry
Linkwitz Transform edits are staged behind Apply and Revert, and a band's values are sanitized when it changes to or from an LT so a leftover gain cannot land as a target frequency
Band gain carries three decimals end to end, and Q exports at the precision the app holds
Link any adjacent pair of input channels, not just 1/2, and the joint page closes from either linked row
Graph curve toggles moved into the sidebar channel pills, which are brighter and now drawn from one definition per channel color. The dashboard keeps its pills when you leave a channel page
Value fields require Cmd to change by scrolling, so a stray scroll cannot alter a setting

Universal build (Apple Silicon + Intel). Ad-hoc signed: on first launch, right-click the app and choose Open.
