Smaart to Lake Overlay Converter

Export your EQ overlays from Smaart Data Modeler as a .lpif file and convert them to Lake Controller overlay files (.ovl) — one file per DSP channel, with filter type, frequency, gain and bandwidth all carried across. What used to take an hour of manual entry takes seconds.

Workflow

What the converter does

One overlay file per channel

Each DSP channel in your Smaart Data Modeler export becomes its own Lake Controller .ovl file, ready to recall directly in Lake.

Full filter data preserved

Filter type, frequency, gain, and bandwidth (Q) are all extracted from the .lpif and mapped to the Lake overlay format exactly.

Visual EQ preview per channel

The tool renders a frequency response curve for each channel before you download, so you can verify the import parsed correctly.

Batch download

All channel overlay files are packaged and downloaded in one action — no need to export channels one at a time.

Runs entirely in the browser

The .lpif file is parsed locally in JavaScript. Nothing is sent to a server — suitable for measurement data under client NDA.

No plugin required

Works with the standard .lpif export from Smaart Data Modeler. No additional software, no setup, no installation.

File formats

Input

Smaart Data Modeler export

.lpif

Generated by Rational Acoustics Smaart's Data Modeler module. Contains EQ filter data per measurement channel — filter type, frequency, gain, and bandwidth. Export via the Data Modeler export function in Smaart.

Output

Lake Controller overlay files

.ovl

Native Lake Controller overlay format. One file per DSP channel. Import directly into Lake Controller to apply the EQ overlay to the corresponding processing module.

Who uses this

This tool is for live sound system engineers who use Lake processing (LM26, LM44, or similar) as part of their system alignment workflow, with Smaart as their measurement and analysis platform. The Smaart → Lake path comes up on large-scale touring and fixed-installation projects where measurement overlays need to be turned into processor settings quickly and accurately — particularly for multi-channel systems where manual entry across many DSP channels introduces risk of transcription errors. This converter is used by system engineers working in the Netherlands and across Europe.
