One suite, with the three tools it grew out of folded in

RF & wireless tools

Radio mic coordination that speaks every format.

Frequency coordination lives in three incompatible file formats and a spreadsheet somebody emailed round in 2019. Shure won't read Sennheiser's files, Sennheiser won't read Shure's, and Ofcom sends you a PDF.

RFutils is the answer to all of that in one browser app. The three standalone tools it grew out of (WSM–WWB Bridge, PMSE to WWB and MicWizard) were folded into it and archived on 11 October 2026, and their conversion, their monitoring and their fixes all live in RFutils now.

RFutils — RF coordination and radio-mic monitoring

Where the standalone tools went

RFutils, for all of it. The file parsers were re-implemented in TypeScript and checked against the originals rather than rewritten from memory; the last differences, in rounding, were closed in v0.5.0 and checked against the bridge's own Python on 450,008 values.

MicWizard's monitoring became the Monitor tab, with its Shure and Sennheiser fixes, its headphone cue options and a one-click import of its Companion routing. WSM–WWB Bridge and PMSE to WWB became Convert. Their repositories stay readable on GitHub as archives.

Diagram: Shure Wireless Workbench files, Sennheiser WSM files, an Ofcom PMSE licence PDF and receivers on the network all go into RFutils, whose Convert, Monitor and coordination tabs produce WWB and WSM import files; beneath it the three standalone tools mapped to the tabs they became, WSM-WWB Bridge and pmse-to-wwb to Convert and MicWizard to Monitor — The formats in, the files out, and where each retired standalone tool ended up inside RFutils

A standing warning

Almost none of this is built on published specification. Neither Shure nor Sennheiser document these formats fully, so they were reverse-engineered from real exports and real hardware. The Ofcom parser is calibrated to a fixed template and a materially different revision would need re-calibrating.

It works, and it's been checked against genuine files, but check every export against your own WWB or WSM install before you rely on it for a show.
