Headphone EQ
Optimize your headphone's frequency response in three steps:
- 1 Load measurements — Select your headphone model from the built-in database or import a frequency response file. SotF includes data for hundreds of popular headphones.
- 2 Optimize — Choose a target curve (Harman, diffuse-field, or custom) and run the optimizer. SotF calculates the optimal parametric EQ filters to match your target.
- 3 A/B compare — Toggle the EQ on and off in real-time to hear the difference. Fine-tune individual bands if desired, then save your preset.
Room EQ
Correct your room's acoustics with the guided wizard:
- 1 Load speaker data — Select your speakers from the spinorama.org database or import measurement files.
- 2 Room configuration — Define your room layout: speaker positions, listener position, and channel configuration (stereo up to 9.1.6 Atmos).
- 3 Configure parameters — Set target curve preferences, frequency range, and maximum EQ boost/cut limits.
- 4 Optimize — Run the room EQ optimizer. SotF calculates per-channel parametric EQ filters to flatten your in-room response.
- 5 Review — Inspect the before/after frequency response curves for each channel. Adjust individual filters if needed.
- 6 Export — Apply the EQ live, or export to APO, RME TotalMix, macOS Audio Units, or JSON for use in other systems.
Plugin Rack & Graph
SotF offers two ways to manage your audio processing chain:
Linear Rack View
A simple top-to-bottom plugin chain. Drag to reorder, click to configure, toggle individual plugins on/off for A/B comparison. Great for straightforward setups like EQ → compressor → limiter.
DAG Graph Editor
A visual node-based editor for advanced routing. Split signals, process channels independently, merge them back — perfect for complex setups like binaural processing, multi-band compression, or surround upmixing.
