REW Beta Release REW API beta releases

[Phil Pope]

Preferences help section says:

"Make sure that the input channel is the one connected to your SPL meter (or mic preamp output). If Use loopback as timing reference has been selected in the Analysis preferences the other channel will be used a reference to remove time delays within the computer and interface, this requires a loopback connection on the reference channel."

I can't see any "Use loopback as timing reference" option.

That's on the Measure dialog in 5.40.

Hi, I'm testing the REW API. Cool idea! It looks like it should be possible to set the PEQ on a WiiM Ultra streamer automatically from REW measurements, for faster, "simpler" adjustments.

I am getting an error and this is just about error handling. If the measurement isn't selected in the GUI, REW throws an NPE (error dialog) during the import/EQ setup calls, and Match target then never reports completion. If you select it first, it's OK. Details below.


Environment: REW V5.40 Beta 135, Eclipse Adoptium JRE 17.0.20.1 64-bit, macOS 27.0.1, started with -api.

Steps to reproduce:
1. Start REW fresh with the API: open -a /Applications/REW/REW.app --args -api. No measurements are loaded, and GET /measurements/selected returns 0.
2. POST /application/blocking with body true.
3. POST /import/frequency-response-data with {"identifier":"npe-repro","isImpedance":false,"startFreq":20,"ppo":48,"magnitude":"<base64 BE float32[]>"}. This is a synthetic response from 20 Hz to 20 kHz. → Import … ID 1 completed
4. Don't select the measurement. GET /measurements/selected still returns 0.
5. POST /measurements/1/equaliser with {"manufacturer":"Generic","model":"Configurable PEQ"}. → Equaliser selected
6. PUT /measurements/1/target-settings with {"shape":"Full range"}. → Update processed
7. POST /measurements/1/eq/command with {"command":"Calculate target level"}. → Completed
8. POST /measurements/1/eq/command with {"command":"Match target"}.

Expected: Match target finishes and returns 200.

I am getting an error

Thanks for the report, I've fixed that for the next build.
