LARK 0.4.1

Latest

2026-11-04

Import Audio Files adds the files as new tracks to the open session instead of replacing it. You can also drag and drop audio files (or a .lrks session) onto LARK.
Clips show the track's WAV file name. Tracks recorded for only some songs show clips only where they were recorded.
Recording only some tracks in Multi: the other tracks stay visible in their order, keep their REC buttons after stopping, and show nothing in their lanes. Input meters move only on armed tracks.
Fixed: LARK crashed when stopping a recording that added a new track to a recorded session.
Switch pre-record tracks between mono and stereo (right-click a track name; works on all selected tracks).
Make a Click: no clicks during MCs between songs (stops where no beat is heard for 8 beats or more; adjustable).
Changing the skin or language keeps the Big Clock, large RTA and Session Note windows open where they were. Fixed overlapping labels in the top bar of narrow windows.

Import channel names from an input list: drop a screenshot, photo, PDF, Excel (.xlsx) or CSV of the input list and LARK finds the channel numbers and names on this computer (no AI, nothing is sent). Tuned on real-world input lists: tight columns, names split over two columns, small text on dense A4 sheets, missed headers. Check the names in the table, then apply. Excel and CSV are read exactly; PDFs and images go through text recognition.
Track notes (right-click a track name; a small note mark shows them) and a Session Note window (View menu) that stays on top and follows the skin; both are saved in the session.

Update from inside LARK: "Update Now" downloads the new version, checks it, and restarts LARK, with no security prompt on each update.
New skin: Light, a bright theme that stays readable outdoors in daylight.
Folder and file names follow the display language (e.g. Rehearsal, Multi, Song, Click), and names in any language are made safe on every OS.
Fixed: the Stop button did not stop recording after changing the skin or language.
Fixed: the 2Mix (and other) input could not be chosen while a recorded session was open; pick it with the In box next to the record button.

Halloween edition: new Halloween skin (a witch LARK on a broom, jack-o'-lanterns, cobwebs and Halloween track colours) and a Halloween app icon.
Make a Click (Edit menu): build a click track from a 2Mix recording, with a fixed tempo per song, bar accents and per-song bar start. Clicks now sit on the beat on real recordings.
Input device "This Mac's sound" / "This PC's sound": record what plays on the computer (at -3 dB).
Polar Level view (click the goniometer): per-band position and phase, with peak hold. Correlation now has 120 bands.
Multi-patch: send a track to several outputs at once (track Out menu, or Cmd / Ctrl-click in the Patch Matrix).
Clips are selected and deleted per track (Shift / Cmd-click to add, Cmd+A for all); delete a clip on one track only, or on all tracks from the right-click menu.
Templates: load any session (.lrks) as a template and choose what to take over. The .lrkt template files are no longer used.
Time display: right-click to choose the format, left-click to type a time and move there.
Pan display: L100 - R100 or L63 - R63 (Settings > Display). M / S buttons also work on tracks without a waveform.
Invite Engineers (Help menu): share your personal link; every engineer who applies for the beta through it earns you a discount on LARK 1.0.
More robust recording at high channel counts (tested: 256 ch at 96 kHz, 64-sample buffer, no dropouts on an 8 GB Mac).
Fixed: Chinese UI text disappearing on Mac (0.3.4); transport buttons overlapping in narrow windows.

2026-10-29

Fixed: mixed fonts in Chinese, Korean and Thai.
Track M / S buttons moved next to the track name and shown in every mode (also while recording).
Patch In / Out labels stay in English in every language.
Wider track headers, so longer track names fit.
New (Mac, macOS 14.2+): record the sound playing on this Mac as two extra inputs, Mac L / R (Settings > Audio Device). No driver needed.
Settings: Input is now listed above Output.
Windows: record the sound playing on the PC as inputs PC L / R.
Time Align: shows the time offset and polarity between two tracks (e.g. kick in / out, snare top / bottom).
Big Clock window (View > Big Clock...): the time of day, resizable, 12- or 24-hour.
RTA: new multi-time-window engine (fine resolution in the lows, fast response in the highs), smooth curves and motion (60 updates a second), and 1/24 and 1/48 octave views.
RTA: choose the range (24 to 96 dB), averaging time (0.1 to 3 s) and level scale (per band, or 1-octave equivalent); drag the dB scale or use the mouse wheel to move the graph up / down; right-click for the menu.
Large RTA window and Big Clock stay on top of the LARK window.

Channel names from Yamaha DM3 / DM7 (same Yamaha option as CL / QL / RIVAGE PM; falls back to OSC automatically).
Diagnostics for Yamaha consoles too.
Channel names from Allen & Heath dLive / Avantis and Behringer X32 / Midas M32 (also X Air / MR).
Patch Matrix shows the interface channel names, grouped (e.g. "MADI" over 1 2 3 4 ...).
Languages: English, Japanese, Chinese (Simplified / Traditional), Korean, Spanish, French, German, Italian, Portuguese and Thai (View > Language).
Setlist: enter the songs beforehand; Next (N) adds a marker with the next song name, MC (M) adds "MC #n".
Large RTA window (resizable).
Custom RTA reference curves: draw your own with octave sliders, or capture the current sound (10 s average).
Tempo (BPM) detection next to the transport clock; click for x2 / /2.
RTA: line only, plus reference curves (Rock, Pops, EDM, Hip-Hop / R&B, Jazz / Acoustic, Pink); drag up / down to move.
Export: 4 ms fade in / out at the start and end of each file to avoid clicks.

Fixed: importing DiGiCo channel names could hang at "Connecting..." when the console did not report its channel count.
DiGiCo ports now work like the iPad app: LARK Send = the console's Rcv, LARK Rcv = the console's Send.

2026-10-26

New: Help > Send Feedback / Report a Bug. Send us bugs and ideas right from LARK (system information is optional and shown before sending; recordings are never sent).
DiGiCo channel names: Diagnostics button showing everything sent to and received from the console; Rcv / Send port labels; more tolerant of how the console replies.

Zoom in to individual samples: the waveform is drawn from the recorded audio down to a single line and sample dots, with a millisecond ruler.
Find Consoles button in Import Channel Names (searches the network for Yamaha consoles).
New tracks are Blue by default; "Give each track a different colour" option in Add Track.
Patch Matrix keeps the channel names visible while scrolling.
Clearer help when a console can't be reached (use the console's control port IP, not the Dante IP).
Find Consoles no longer scans this computer's own addresses or 169.254.x.x.
