I'm happy to announce the release of ToneShiftEQ 0.6.0!

This release introduces several major new features and expands ToneShiftEQ beyond a traditional minimal phase EQ.
What's New
Dynamic EQ

ToneShiftEQ now supports Dynamic EQ processing. Each band can react dynamically to the incoming signal, making it possible to apply frequency-selective compression while maintaining the familiar workflow.
Equalizer APO Support

ToneShiftEQ can now import and export Equalizer APO configuration files, making it easy to exchange EQ settings with Equalizer APO and integrate existing APO profiles into your workflow.
Impulse Response Load & Save

ToneShiftEQ can now load and save impulse responses. When an impulse response is loaded, its frequency response is automatically analyzed and approximated as a 12-band parametric EQ, allowing IR-based tonal characteristics to be recreated without using a convolution engine.

Note: The approximation is designed to capture the overall tonal balance of the impulse response rather than reproduce it sample-for-sample.

Note: IR loading and saving is currently not available in the LV2 version, as transferring large IR data through the LV2 state interface would introduce excessive overhead.
Other Improvements

Numerous internal improvements and optimizations.
Enhanced workflow for exchanging EQ settings and impulse responses.
Various bug fixes and stability improvements.

As always, feedback, bug reports and feature suggestions are welcome.

ToneShiftEQ12 is a 12-band minimum-phase parametric EQ, available as LV2, CLAP and VST3 plugin.

ToneShiftEQ provide two processing engines:

• FFT Mode – minimum-phase convolution with advanced spectral controls (128 samples latency).
• Biquad Mode – a traditional cascaded biquad implementation with zero latency for real-time use.

New in this release:

• Windows support (Clap and VST3)
• Linux VST3 support
• Fix issue with the Shelf Filters

Feedback, testing, and bug reports are very welcome.

I'm happy to announce the first public release of ToneShiftEQ, a modern 12-band equalizer designed for precise spectral shaping, mixing, mastering, and corrective audio processing.

ToneShiftEQ is available as a standalone application, LV2 plugin, and CLAP plugin.

It provides two processing modes for different workflows:

• Master Mode → Perfect linear-phase response with 128 samples latency for precise mastering and critical processing.
• Live Mode → Zero-latency processing with slight phase deviation, optimized for real-time use and live performance.

For CLAP builds, both modes are available as dedicated plugins:

• ToneShift-EQ12M
• ToneShift-EQ12L

Feedback, testing, and bug reports are very welcome.

NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows available as Stand alone application, and in the Clap, LV2 and vst2 plugin format.

It supports *.nam files and, or *.json or .aidax files by using the NeuralAudio engine.

For Impulse Response File Convolution it use FFTConvolver

Resampling is done by Libzita-resampler

New in this release:

• Fix support for dpi scale
• Fix stand-alone may crash on wayland
• implement support for NAM outboard models, they could be loaded in the IR module now.

SmoothIR is a lightweight tool for creating and shaping impulse responses with a strong focus on clarity, control, and real-time feedback.

This Release introduce SmoothEQ:

SmoothEQ is a

Linear Phase EQ based on Impulse Response Processing as Clap Plugin

What started as an experimental IR tool evolved into something much bigger: a flexible linear phase EQ, spectrum matching processor, IR shaper, and lightweight IR creator in one plugin.

SmoothEQ can work in multiple ways:

• Load a reference audio file to visualize its spectrum and shape your input towards the tonal balance of the reference.

• Load a source file to automatically generate an EQ curve from its spectrum, then fine-tune it manually with the built-in EQ controls.

• Load both a source and reference file to create a match EQ curve representing the spectral difference between them — effectively generating the correction needed to move the source closer to the reference.

• Or simply use SmoothEQ as a transparent 6-band linear phase EQ with additional low cut and high cut controls.

The generated EQ curve itself is highly flexible:

• The Smooth control evens out harsh frequency jumps and creates more natural curves.

• The Dynamic control can enhance spectral contrasts and emphasize details when needed.

• Tone Bias shifts the tonal focus between low-end warmth and high-end presence.

Each band includes Solo and Mute functionality, allowing detailed inspection of how individual regions affect the mix. Due to the nature of linear phase processing, complete frequency isolation is not always physically possible without introducing phase shifts — SmoothEQ intentionally avoids those artifacts while still providing meaningful band auditioning.

SmoothEQ can also export its EQ curve as an impulse response file.

This makes it possible to transform large, CPU-heavy IRs into lightweight minimal phase impulse responses suitable for embedded systems, hardware devices, low-latency environments, or resource-limited convolution engines. Export size can be freely selected depending on quality and performance requirements.

Additional features include:

• Real-time spectrum visualization

• Stereo IR processing

• IR loading and reshaping

• Zero-latency FIR head with efficient convolution backend

• Adjustable IR export length

• Smooth spectral morphing workflows

• Match EQ style analysis without destructive processing

• High precision double-based internal processing

SmoothEQ is designed for sound design, mastering, corrective EQ, IR optimization, tone matching, and experimental spectral processing — all inside a single workflow.
