Listen up – one of the biggest struggles we face when mixing entirely in the box is getting echoes and choruses to sit in the mix without washing out the whole track. Standard digital delays often lack that analog glue, leaving your vocals or guitars sounding thin, sterile, and disconnected from the beat.

You end up EQing the life out of the delay return just to make it fit. But today, I’m bringing you some serious sauce that instantly solves that problem by injecting authentic, gritty tape vibes straight into your DAW.

Why NastyDLA mkIII is a Game-Changer for Your Mix & Workflow

This isn’t just an update; it’s a massive sonic upgrade. The homies over at Variety of Sound completely overhauled this beast. Here is why this plugin is about to become your go-to delay:

• Instant Analog Warmth: The newly refined input stage features an audio transformer circuit simulation. What does that mean for you? Harmonically rich, fat, and detailed sound the second you feed audio into it.
• Smooth, Glued-Together Dynamics: The interplay between the onboard compression and tape saturation has been perfectly balanced. It tames your transients and delivers improved dynamics with reduced distortion, so your echoes melt beautifully into the instrumental.
• Wavy Stereo Width: The delay section has been fine-tuned for incredibly refined stereo imaging. Combined with flexible, expressive modulation, you get that classic, wide chorus vibe that wraps around the listener.
• Pristine Audio Quality: Say goodbye to digital artifacts. This version rocks state-of-the-art oversampling with ADAA and Zero Delay Filtering (ZDF), meaning it sounds expensive as hell without eating up your CPU.

Tech Specs (Keep it Light)

• Format: Windows (WiN) VST
• Size: A featherweight 20 MB (Leaves plenty of room on your hard drive for more drum kits!)
• Under the Hood: State-of-the-art oversampling, ADAA, and ZDF technology.
• Performance: Packed with massive optimizations and bug fixes, making this v3.5 release the most stable and mature version to date.

The Verdict

NastyDLA mkIII absolutely slaps. If you’re tired of fighting muddy, plastic-sounding digital delays, this classic chorus echo device brings that expensive tape-delay simulation to your studio for absolutely zero dollars. It adds undeniable character, width, and an analog vibe that just works. Download it, throw it on a synth or a lead vocal, and watch your mix come to life.

We’ve all been there—you’re working on a beat, the drums are knocking, but the melody just feels… stale. It sits in the mix, but it doesn’t have that “ear candy” factor that keeps listeners hooked. You try a standard delay, but it just muddies up the headroom. That is exactly the struggle Skew solves. This isn’t just an echo; it’s a vibe-creator that reverses and warps your audio to turn boring stems into complex, rhythmic textures.

Why Skew is a Game-Changer for Your Mix & Workflow

If you produce Trap, IDM, or even Cinematic scores, you know that texture is everything. Skew takes a unique approach by constantly recording your audio and spitting it back out in reversed chunks. But it’s the non-linear aspect that really brings the heat.

Here is why this plugin creates instant inspiration:

• Total Rhythmic Control: It syncs perfectly to your host transport, meaning your glitches will always be locked in time with the groove.
• Unique Pitch Bending: Unlike standard delays, Skew uses 12 different non-linear curves to warp playback speed. This gives you those crazy tape-stop and pitch-slide effects without complex automation.
• Clean Feedback Loops: The triple-playhead design is genius—one head handles feedback while two handle playback. This means your pitch-bending effects don’t get messy or dissonant as they repeat.
• Smooth Automation: They included lag filters on all parameters, so you can tweak knobs live or draw in crazy automation clips without any nasty digital clicks or pops.
• Versatile Routing: Whether you are working mono-to-mono or want to widen the stereo field, this plugin handles the signal flow effortlessly.

Tech Specs (Keep it Light)

Here is the lowdown on compatibility. It’s pretty lightweight (only 14MB), so it won’t eat up your CPU.

• Mac: AU, VST3, AAX (macOS 10.13+, Intel & Silicon native).
• Windows: VST3, AAX (Windows 8.1+, 64-bit).
• Linux: VST3 (Ubuntu 20.04+, 64-bit).
• Space: A tiny 14 MB download.

The Verdict

Look, standard delays are bread and butter, but Skew is the hot sauce. It takes a static sound and gives it movement and character that is hard to replicate with stock plugins. The interface is slick, the triple-playhead engine is smart, and the pitch-warping capabilities are perfect for modern production styles. If your tracks are feeling a little too “safe,” this is the tool to dirty them up.

That’s where Dynaverse steps in. This isn’t just a static echo chamber; it’s a dynamic tool that actually listens to your audio. Whether you need your tails to duck out of the way when the kick hits, or you want a flanger to swell up only during the quiet parts, this plugin brings that “breathing” effect that makes a track feel alive.

Why Dynaverse is a Game-Changer for Your Mix & Workflow

This plugin is all about movement and modulation. It takes the concept of a standard delay and injects it with a serious dose of creative routing. Here’s why this plugin deserves a spot in your folder:

• Reactive Mixing: With the input volume automation (the pink controls), you can make the delay duck or swell based on the incoming signal. This keeps your mix clean and ensures the effect sits perfectly in the pocket.
• Dual-Threat Modulation: The purple control lets you switch routing between Chorus and Flanger modes, giving you instant access to wide, shimmering textures or deep, metallic sweeps.
• Rhythmic Automation: The built-in LFO (yellow controls) allows you to automate parameters based on a cycle, adding a constant, evolving groove to your sound design.
• Visual Workflow: The color-coded system (Red for static, Pink for volume input, Yellow for LFO) makes it super easy to see exactly what is modulating your sound at a glance.

Tech Specs (Keep it Light)

• Format: VST (Windows & Mac)
• Size: A chill 36 MB (won’t clog your drive)
• Key Features: Chorus/Flanger routing, LFO generation, Envelope Follower.

The Verdict

If your sound design is feeling a little stale, Dynaverse is the sauce you need. It’s rare to find a free tool that handles dynamic modulation this intuitively. It’s perfect for dub techno chords, spacey trap melodies, or just adding some weird artifacts to a drum break. It slaps, it’s free, and it’s ready to work.

Glitch delay geared toward creating robotic artifacts and musical malfunctions.

Hysteresis is a versatile effects processor geared toward electronic musicians and sound designers. Process anything from drums to synths, guitars, vocals and sound effects. On top of being able to create contorted signal mutations, it can also be tamed to generate classic delay effects.

Hysteresis features a delay effect with stutter, lowpass filter and modulation effects thrown into the feedback signal path. The input signal first goes through a delay line on each stereo channel, but instead of sending the output directly back into the delay line, the resulting signal is sent to a stutter processor, then to a lowpass filter and finally to another delay line on the opposite channel which is modulated for creating chorus type effects.

The output of the second delay line is then routed back to the first one on the original channel. The stutter effect can be used to generate reverse delays, noisy pitch-shifting or raw granulation. The lowpass filter has an internal LFO to make the cutoff frequency oscillate, and the modulation processor can act as a subtle chorus or noisy modulator depending on the range of the modulation rate.

Pitchshifting Dual Delay

Set different harmonies for the left and right channels. For example, -12 will be an octave below, and 7 will be a fifth (7 semitones) above. The Balance control can be used to emphasise one side over the other.
Use Delay and Feedback, along with LFO and Frequency, to set the length and character of the delays.
For more complex arpeggiations, try using two instances of Angel Dust at the same time.

Tymee is a free delay plugin. Designed with simplicity in mind, it offers straightforward controls and quality sound.

It features a 10 seconds delay line with tap tempo functionality, a down-sampler, a low-pass resonant filter and a built-in spectrogram for real-time visualization.

You might wonder why a delay plugin would include a spectrogram. The truth is, Tymee was originally developed for teaching audio programming at a university, and incorporating a spectrogram into the workshop was valuable for educational purposes (and also because it looks great!).

Requirements:

Win 10 or later – macOS 10.15 or later

Digital models of the Roland RE201. VST3, AU plugins and source code.
The original folder contains a (mostly) header only library implementing four seperate digital models of a Roland RE-201, developed throughout the duration of my final year project, on the BSc Sound Engineering and Production course at Birmingham City University. The models are classes which can be implemented into an audio plugin in any framework.

The latest version is a significant improvement of the original and is not header only. This is dedicated to optimisations which did not fit into the time scale of my bachelors project and generally cleans up the code. This includes processing by buffer instead of sample, optimising the filter structures, adjustments to the WDF tone stack, reducing unnecessary calculations and dynamic allocation of objects and memory based on channel count. The error function tape saturation model has been omitted (because lets be honest, tape hysteresis modelling is way cooler), however the tone stack algorithm can be switched between VA and WDF by setting a bool variable in the RE201model class.

The four models implemented combinations of two tape saturation and two tone stack modellings methods. One tape saturation modelling method was a static non linearity (error function) and the other was based on the hysteresis processor developed by chowdhury (2019) which calculates magnetisation based on a tape playhead position derivative approximation. The tape delay modelling between the two methods is the same, utilising three circular buffers with read times at multiple of each other, in line with the real device (Using a single buffer with multiple read heads was tested, however this appeared to generate phasing issues when multiple playheads were active). Both methods implement oversampling, albeit very inefficiently. The latest version attempts to resolve many of those issues.

The first tone stack method implemented the VA Bassman 59′ filter discretised by Yeh (2006). The other tone stack was two WDF shelving filters processed in series to make up the bass and treble frequency bands.

Other perceptual characteristics have been modelled, this includes wow and flutter (although this is next on my improvements list), control ballistics (pitch increases when the repeat rate is increasing and vice versa) and tape speed dependant equalisation.

Included in both versions is the respective Windows VST x64 plugin and ASPIK project which can be built for Mac OS. Mac OS versions will be added shortly.
