From installation to your first EQ in about ten minutes.
Download the latest Windows installer from this website. EQing supports 64-bit Windows 10 and 11.
Open the installer and follow the prompts. Windows may request administrator permission during installation.
No sign-in or activation is required. Playback, EQ, upscaling, exciter, listening effects, spatial audio, DSD, and AI EQ are all free.
Add a local music folder to the Library, or follow the VB-CABLE section below to process audio from a streaming app, browser, or game.
VB-Audio VB-CABLE is donationware that can be installed and tested for free. It sends audio from another app into EQing so only the processed signal reaches your headphones or DAC.
Download the Windows package, extract the entire ZIP, run VBCABLE_Setup_x64.exe as administrator, click Install Driver, and restart Windows.
Set Spotify, your browser, game, or other source app to CABLE Input (VB-Audio Virtual Cable). Windows per-app sound settings let you route only selected apps.
In Settings, choose Loopback → WASAPI. Select the same CABLE Input as the capture device and your real headphones, DAC, or speakers as the output device. Disable exclusive mode in the source app.
Click Apply Output, then Start Capture. If the cable is missing, refresh the device list or restart EQing. For dropouts, match the shared-mode sample rates of CABLE Input and the physical output device.
Select the gear icon in the left sidebar.
WASAPI Exclusive offers a direct bit-perfect path. WASAPI Shared is the most compatible and mixes other apps. Loopback processes audio from another app or device.
Choose the desired output from the device list and click Apply Output.
The response graph and filter list let you see and edit the complete curve.
Drag points on the graph or enter frequency, gain, and Q values directly in the filter list.
Use REW / AutoEQ Import to load a compatible ParametricEQ.txt file.
Turn EQ on, confirm your preamp and headroom, then save the curve as a preset for later use.
Open AI EQ Assistant, then use Open model download page to download the Gemma 4 E2B GGUF file, approximately 3 GB. Ollama is not required.
Choose the downloaded model in EQing. The saved path is reused next time. If loading fails because of the path, move it to an English-only path such as C:\Models\model.gguf.
Try “clearer vocals, tighter bass, and a little more air.” The assistant explains the moves and applies a safe parametric EQ.
Continue the conversation to adjust the current curve. Saved sessions can restore both the EQ and its conversation history.
The model runs locally through LLamaSharp and llama.cpp. Prompts are not sent to a cloud service, and the assistant works offline after the model is downloaded.
Extract the downloaded ZIP before installation, run the x64 installer as administrator, restart Windows, and then refresh EQing's device list.
The source app output and EQing capture device must both be CABLE Input. EQing's output must be your physical listening device. Apply the output and then start capture.
Use a physical output device that is different from the capture source and make sure the source app is not also playing directly to that device.
Lossless: FLAC, WAV, AIFF, ALAC, APE
