July 09, 2022 v 1.395

• Apple Silicon Native Support: VST3 and AU both can run natively on new Macs.
• [NEW] You can now hide gain changes from the DAW in AUTO mode (helpful to keep DAW history clean and use 'Undo' on another plugin). Uncheck option "Global Preferences - Expose to DAW - Gain in AUTO". When this option is unchecked, you'll see "W" (write) icon near AUTO (when it is on) to enable writing automation when you need to.
• [NEW] collective "listen before/listen to delta". Right-click on "Listen before" to display "Collective controls". Clicking on "*" toggles all instances in project, clicking on "link" icon toggles a collection. To create a "collection" drag "Listen before" button onto another instance. Right-click on "link" icon to unlink from collection. Press and hold for a while to lock "*" or "collection" modes. This way you can listen to "before/after" on multiple tracks simultaneously. [ Alternatively CTRL+Click on "Listen before" toggles all instances, Alt(Cmd)+Click toggles collection. ]
• [New option] Turn off all AUTO in project using right-click menu on AUTO.
• [Experimental] New option for calculating the difference 'Consider "Listen gain" value when displaying difference'. You can use if you like to adjust listen gain and want the difference value (and so the main knob) to follow that. When it is enabled, AUTO for 'Listen before' is hidden and disabled.
• Improved 'Suspend comparison' and overall behaviour when audio is below the threshold. Added adjustable 'Threshold' parameter (gray line displayed over the left meter when suspend comparison is enabled).
• Increased maximum number of groups to 128 (recommended to use less: 24 by default, for faster loading and reducing RAM usage)
• [Experimental] Added a config option for increasing maximum ASIO block size (larger than 4096). Shift+right_click on Global Settings -> Edit settings file
• Reworked/rewritten Ear Protection mode (a system preventing huge volume jumps in AUTO mode when the gain is high). It should work more reliably now with less false positives. Also now there's an "ear" icon showing when it's working.
• [GUI] Slightly larger "Listen before" button
• [GUI] A "Before" hint when listening to "before" (can be turned off from "Look and feel" menu)
• [GUI] Slightly increased contrast in Light theme
• [GUI] Animated timer icon showing remaining time to start comparison
• [GUI] Removed a "Conflict" warning when instance is just loaded and is auto-selecting group and mode
• [GUI] Removed obsolete "Classic groups menu" and "Extended width" options
• [GUI] Added a warning icon when Trim is not 0, but hidden
• [GUI] Quick menu to display/hide statusbar items - click on the "status" icon in taskbar (bottom left corner)
• [DAW/Controls] "Compensate" button now is properly seen by the DAW (when enabling "Global preferences -> Expose to DAW -> Compensate (difference)") and thus can be easily "learned"
• Better detection when plugin is bypassed in the DAW
• Fixes and improvements regarding AUTO behavior
• Fixes regarding writing automation in some hosts (e.g. Logic, Cubase)
• Fixed shared memory issue when using GainMatch on multiple accounts on Mac
• Fixed "check for updates" option could take too long on Mac
• Fixed: Ableton Live sometimes couldn't instantiate a plugin

May 05, 2021 v 1.32 / 1.22

• Improved/reworked audio sending and loudness measurement for hosts with dynamic block sizes (FL Studio, Logic, Pro Tools)
• Set default RMS value from 3 to 2 seconds (for new installations): makes GainMatch more agile still providing good results. Right-click on RMS time and use "save as default" to set your own default RMS time.
• Temporarily reverted to old method of writing automation (introduced in 1.211/1.311), because new method could misbehave in some DAWs
• Fixed "Target Loudness Mode" was sometimes not working (a bug introduced in v1.215/1.315)
• Fixed "Reverse link" icon was not restored in "Before" upon loading preset in "After"

April 26, 2021 v 1.315 / 1.215

• Improved option `Go to 'Neutral' if no pair within 30 seconds`: now works also for 'Before' instances that don't have an 'After' pair
• Improved: When inserting 'After' it now outputs the difference value only after collecting enough audio (RMS time, 3 seconds by default)
• Improved: the difference value is now grayed out when it cannot be properly calculated (no signal, etc)
• Fixed "Listen before"/"Delta" crossfades issues when using large buffer size (4096)
• Fixed "Before" could be stuck in delay detection mode (and output silence) when duplicating the track
• Updated the manual

March 26, 2021 v 1.312 / 1.212

• Fixed mono to stereo behaviour
• Fixed sending audio bugs

March 21, 2021 v 1.21

• "Measure before loudness after knob" was renamed to "Send audio and measure before loudness after knob" - now "before" audio can also be sent after the gain knob.

• Fixed bug with UTF-8 characters in userdir
• Fixed graphics issues on some MacOS versions

March 01, 2021 v 1.206

• Improved loading time
• Reorganized 'options' menu
• Fixed default pan law
• Fixed "Compensate" button behavior

February 09, 2021 v 1.19 (beta)

• Greatly improved RAM and CPU usage. GainMatch now is x3.5 to x7.5 times lighter on the CPU and uses up to x9.5 times less RAM (depending on the settings).
• Shortened the right-click menu, now it contains only the most frequently used options. A full list of options (for current instance) can be found in the "Options" menu (dropdown icon in the toolbar). Global default options (for new instances) can be found in "Global Preferences -> For new instances...".
• New icon for "Global preferences" (the `cog` icon on the toolbar). Everything related to global and default settings is there. Also accessible via shift+right-click on an empty area.
• Option to "Save as default (for new instances)" to quickly save current options as default.
• New combo Scale/Opacity icon (right-click to toggle)
• Option to "Keep 'Delay' visible": display 'Delay' even when not 'listening before'.
• No need to select delay buffer size now, it is adjusted automatically. Delay detection can detect delays up to 900000+ samples and it also detects the polarity of the signal.
• Now you can auto-detect delay for new "After" instances upon inserting ("Global Preferences -> For new instances... -> Auto-detect delay for new after")
• You can also enable "Auto" or "Auto listen gain" for new instances upon inserting
• "Delta" is now displayed as a separate button (you can display it from the menu). You can still use shift+click on "Listen Before" to temporarily toggle "Delta".
• New "Listen polarity" indicator/control (hidden by default). Polarity is detected during delay detection.
• Added short crossfades while switching before/after/delta to prevent clicks
• Fixed possible issues related to "reverse-linking" (unexpected gain changes upon reloading when instances were linked).
• Now in "Before" you can see if the gain is linked to "After". Click to unlink.
• Now loudness calculation for Before-After with delays is sample-accurate (it was block-accurate before).
• Slightly bigger group menu items when using only 8 groups (fewer groups = better performance)
• Improved "Fine" resolution on "Sender Gain" and "Gain" knobs (when holding shift)
• Buttons "Auto", "Compensate" (the difference), "Detect delay", "Listen before" and "Delta" can now be controlled via MIDI-notes (right-click to learn MIDI note, hold Shift to "unlearn")
• These parameters can also be exposed or hidden from DAW (to prevent saving their state in DAW automation/history). See "Global Preferences -> Expose to DAW..."
• Reworked checking for updates: improves performance, shows notification icon in the status bar.
• Added option to wait for enough audio after suspending in before-after mode - can be useful when GainMatch is used on different tracks
• Auto adjustment speed is now slightly faster on differences > 3dB
• (experimental) Auto 'turbo' mode - speeds up auto adjustment x2 times
• "Listen gain" auto adjustment now takes 1 second.
• New "Ear protection mode" (enabled by default) prevents loudness spikes when 'Auto' adds too much gain (over +6 dB).
• It is now possible to set separate positive and negative limits for 'Auto' mode (so that it doesn't increase gain too much)
• 'Auto' state is now preserved when switching modes
• Manual gain adjustments now don't disable 'Auto' (an old behavior can be enabled via "Global Preferences -> Other global settings -> Disable 'Auto' on manual adjustments")
• New 'Auto' option: Return gain to 0 on suspend comparison (disabled by default)
• You can now choose to display delay in samples/milliseconds/beats.
• Added warnings when Listen gain or Listen mix are hidden but not set to 0db/100%.
• Fixed Ableton Live freezing on first save if GUI is opened
• Improved Mono to Stereo behavior. You can choose the correct "Pan law" in Global Preferences (set the same pan law as in your DAW).

November 19, 2020 v 1.13

• Now right-clicking on the "plugin menu" icon opens global settings (it's the last icon in the toolbar, the dropdown arrow)
• Improved delay detection for longer delay times, added hints when delay detection fails.
• Improved: when there's a senders conflict (two 'Before' in one group) now only one sends audio to 'After'.
• Improved Mono/Stereo behavior
• Updated the manual
• Fixed possible issues with restoring gain value upon reloading project
• Fixed Gain Resolution not working correctly

November 17, 2020 v 1.12

• Plugin was renamed from "LM GainMatch" to "GainMatch" (more than half of users voted for that). Please, remove the old "LM GainMatch" plugin if you're updating from earlier version.
• Now you can turn on/off "Delta" while pressing "Listen before" and holding Shift of Ctrl
• Increased "Fine-tune / diff correction" range to +-60 dB for extraordinary uses (like "make `After` 30 dB louder than before")
• Added option "Wait for enough audio in target loudness mode after suspend" (enabled by default, added to "Suspend comparison" menu). Useful when your track has silent areas, and you're using target loudness mode: now after silence it waits until enough audio was analyzed (the RMS time, 3 sec by default) to measure the loudness correctly.
• Now when copying plugin in the DAW the group is preserved when possible (only the Before/After mode changes)
• 'Fine-tune / diff correction' behaviour is now more intuitive: increase it to make "After" louder
• Improved delay detection stability when using with plugins like reverbs and delays
• Fixed: global trim setting was not applied to new instances
• Fixed: 'Listen button' not working in Logic
• Fixed `Group RMS time` control behaviour
• Fixed UI problems in Universal Audio LUNA
• Fixed issues with non-English paths to user directory

November 08, 2020 v 1.1

• Reorganized right-click menu. You can now quickly access "Global settings" holding Ctrl or Shift + Right-click.
• New dark skin theme. Can be enabled from Global settings -> Look and feel
• New (optional) larger width to better fit Pro Tools plugin window (also in the 'Look and feel' menu)
• New popup menu to select the group. More compact, shows group colors and if there is "before" or "after" in the group (such groups will be half/full colored). Old-style menu is still available - can be selected from the "Look and feel" menu or right-clicking on groups.
• Number of groups can be increased up to 64 (more groups require more RAM/CPU). Save and reload project after changing number of groups. Global settings -> Number of groups or right-click on groups
• In 'Listen before' it's now possible to adjust the gain of monitored 'before' signal, so that you can not lower the 'After', but raise the 'Before' while listening. It's nice when your mixes are ready and you don't want to ruin the balance. To enable right-click on 'Listen button' or go to 'More settings -> Listen before options'. The auto-mode for 'Listen gain' has a square LED icon and also it's own tolerance and limit settings.
• 'Delta' option (right-click on 'Listen before' to enable). Inverts phase of the 'before' signal and sums with 'after'.
• "Peak" mode for Target loudness mode. Can be useful for short samples like drums or in other cases, when you want to match to the maximum peak level instead of average loudness. Click on the peak value to reset it.
• Option to measure the "Before" loudness after the gain knob (Measure 'Before' loudness after knob). Can be useful in some scenarios (by default the loudness is measured before 'Before' and after 'After').
• 'Fine-tune' the gain difference (right-click on the difference knob or More settings -> Difference options). So if you feel that the compensated signal is too soft or loud, you can adjust that.
• 'Gain resolution' (global option) can be changed from 0.1 to 0.01 dB. Requires saving/reloading session.
• Option to 'Switch to Neutral if no Before for 30 seconds' (in Global settings). So now if you remove the 'Before' instance the 'After' instance will go to 'Neutral' automatically (to free the group and use less CPU).
• Improved sending audio between tracks (when sender and receiver are on different tracks in the DAW). If you experienced dropouts in this mode, increase the delay in the receiver plugin (displayed when "Listen before" is enabled). Set this delay to multiples of your ASIO/soundcard buffer size, so if your buffer is 512 samples, set it to 512 or 1024 etc. Also you can right-click on "clock" icon (delay detection trigger) and select "Report delay to host". Now this instance of plugin should be delay-compensated by the DAW and your audio will be aligned.
• Improved delay detection. Now it should be more consistent and also work with plugins that introduce large delays (greater than 48000 samples). For detecting large delays you may need to increase "Delay buffer size". Right-click on "clock" icon or Right click -> More settings -> Global settings -> Delay buffer size. The `Delay buffer size` should be a bit higher than the maximum delay you plan to detect. Also keep in mind that bigger delay buffers require more RAM & CPU. You may need to re-detect delay in sessions saved with old GainMatch
• Sender is now aware of the delay offset in receiver to calculate loudness with delay
• Slighly increased "Listen before" button for easier operation
• Fixed writing automation in Logic

• Fixed: proper operation on Mono tracks
• Improved: Auto gain tolerance increased up to +-10dB
