TAL-Reverb-4 Explained: Every Control on the Free Plate Reverb, Built-In Ducking, and a Settings Chart by Job

The short answer: TAL-Reverb-4 is a free plate reverb from TAL Software with what the developer calls "a vintage 80's character": modulated, very diffuse, and quick to build up even on long tails. The main section has five faders (Size, Damp, Delay for pre-delay, Diffuse and Stereo) and separate Dry and Wet faders, and around them sit built-in ducking with a sidechain switch, modulation, a Tune pitch shifter, an EQ with low cut, high cut and a peak band, and a lo-fi section for bit depth and sample rate. For a vocal plate, put it on a send with Dry at 0%, set pre-delay to 30 to 80 ms (0.030 to 0.080 s), low cut around 300 Hz, high cut at 6 to 10 kHz, and add a little Ducking so the tail blooms between the words. It runs in VST2, VST3, AU, AAX and CLAP on Windows and macOS (native on Apple Silicon), plus VST2 and VST3 on Linux.

Reverb and delay sends are on every vocal, pad and transition on my releases (Sony, Universal, Ultra, Dim Mak, 50M+ streams). TAL-Reverb-4 is free and there are no affiliate links on this page. I sell a vocal chain with its own reverbs, disclosed at the end.

What TAL-Reverb-4 is

TAL lists TAL-Reverb-4 under its free plug-ins, and describes it as "a high quality plate reverb with a vintage 80's character." The current version at the time of writing is 4.0.4 (August 2023, a new preset browser). The 4.0.2 update brought improved reverb quality, the Damp control, bit depth and sample rate controls and a new interface; earlier 3.0 updates added the ducking mode, a harmonic engine, the peak EQ and the stereo amount control.

Two things to know before you load it:

• It's one algorithm, a plate. There are no room, hall or chamber modes. You get bigger or smaller spaces from Size, and the character stays a smooth, modulated plate.
• Stereo only. TAL says only stereo channels are supported, so put it on a stereo send or bus, not a mono insert.

It runs on Windows 7 or later, macOS 10.9 or later (Universal Binary with native Intel and Apple Silicon support), Pro Tools 10.3.6 or later for AAX, and 64-bit Linux. Download it from tal-software.com only.

Every control, explained

TAL doesn't publish a manual for TAL-Reverb-4. The control names below are from the plugin window in TAL's own screenshot, and the descriptions follow TAL's product page and changelog where they say what a control does. Where they don't, it's marked.

The plugin also has a preset browser and undo and redo. Version 4.0.2 changed the presets; TAL notes that if you upgrade from an older version you need to delete the old preset folder to get the new ones.

The built-in ducking, and why it matters

The most common upgrade to a vocal reverb is ducking: a compressor on the reverb return, keyed from the dry vocal, so the tail drops while the words play and blooms in the gaps. How to add reverb to vocals covers the classic routing. TAL-Reverb-4 builds it in.

On a send that only carries the lead vocal, the reverb's own input is the vocal, so the Ducking knob does the job with no routing at all. On a send shared by several sources (vocals, snare and synths on one plate), ducking from the input reacts to all of them; that's where the S-CHAIN switch comes in, so you can duck from the lead vocal alone through your DAW's sidechain routing. Start around 20 to 40% and listen to the gaps: the tail should rise back between lines, not pump.

TAL-Reverb-4 settings chart, by job

Starting points on a send, with Dry at 0%. Size and the faders are relative, so set the length by ear against the tempo.

On pads, raise the Mod Rate and Amount a little for movement, and try Tune for a shimmer-style layer, used sparingly. For the 80s row, lower Bits and SR until you hear the grain, on its own send so the clean plate stays available. Pre-delay for your tempo is in reverb pre-delay, and the delay and reverb calculator gives every value at any BPM. TAL's Delay fader is in seconds, so 31.25 ms reads as 0.031 s.

How to set it up on a send

1. Download it from tal-software.com only. Free-plugin mirrors are how adware gets installed; the Camel Crusher story is the cautionary tale.
2. Create a stereo return track or aux and insert TAL-Reverb-4 on it.
3. Set Dry to 0% and Wet high, so the return carries only reverb. Control the amount with each track's send.
4. Set Delay for pre-delay from the chart, then Size for the length. On a vocal, the tail should end before the next phrase starts, or just as it does.
5. Filter the return: Low Cut around 300 Hz on vocals, High Cut at 6 to 10 kHz. A darker, high-passed tail sits behind the dry sound instead of on top of it.
6. Add Ducking if it's a vocal send; use S-CHAIN with your DAW's sidechain routing if the send is shared.
7. Leave Tune at zero and the Lo-Fi section clean unless the effect is the point.
8. Check it in the full mix and in mono. Solo, any reverb sounds great; in context you're listening for clarity.

TAL-Reverb-4 vs Valhalla Supermassive

Both are free, and they do different jobs.

The short version: TAL-Reverb-4 for the plate you want under a vocal, Supermassive for the space you want people to notice. Every Supermassive control is in the Valhalla Supermassive guide, and the free and paid field, from Dragonfly to ValhallaVintageVerb and FabFilter Pro-R 2, is in the best reverb plugins.

Mistakes that make it wash out

• Dry left at 100% on a send. You get a second copy of the dry vocal and a phasey, louder track. Pull Dry to 0%.
• No low cut on the return. Low end in the reverb muddies everything under the vocal.
• Zero pre-delay on a lead vocal. The reverb starts with the consonants and smears them; 30 ms or more keeps the words in front.
• A big Size in a busy drop. What sounds huge in a breakdown turns to mud under the full arrangement. Automate the send by section.
• Tune left on by accident. A pitch-shifted tail under a lead vocal can clash with the key.
• Inserting it on a mono track. It's stereo only.

Where I land (and the disclosure)

TAL-Reverb-4 is the free vocal plate to start with: smooth, easy to filter, and the built-in ducking saves a compressor and a routing job on every vocal send.

The Ultimate Vocal Chain is my own version of the whole vocal system in one Waves StudioVerse file, with two reverbs working together on the Reverb macro for color, space and width, plus Delay and Slap macros for the rest of the space. It uses Waves reverbs, not TAL-Reverb-4. The product page has a loudness-matched before/after player, so you can hear it on a real vocal before you buy. It doesn't tune; tune first, then load the chain. I'm biased; TAL-Reverb-4 on a filtered, ducked send gets a vocal most of the way there for free.

Quick answers

Is TAL-Reverb-4 free? Yes. TAL Software lists it with its free plug-ins on tal-software.com, in VST2, VST3, AU, AAX and CLAP for Windows and macOS (native on Apple Silicon) and VST2 and VST3 for Linux.

What are the best TAL-Reverb-4 settings for vocals? On a send with Dry at 0%: medium Size, 0.030 to 0.060 s of pre-delay, high Diffuse, Low Cut around 300 to 500 Hz, High Cut at 6 to 10 kHz, and 20 to 40% Ducking so the tail sits between the words.

Is TAL-Reverb-4 a plate or a hall? A plate. TAL describes it as a plate reverb with a vintage 80s character. Raise Size for a bigger space, but the character stays a plate; for realistic halls and rooms, a reverb with dedicated modes is the better tool.

Is TAL-Reverb-4 better than Valhalla Supermassive? They do different jobs. TAL-Reverb-4 is the better plate under a vocal or snare, with ducking built in. Supermassive is the better pick for huge pads, ambient washes and echo throws.
