Sheaf Music reveal Grapher

Utilise spare devices as a spectrum analyser

Sheaf Music Grapher spectrum analyser on tablet phone spare screen web-based plug-in

Sheaf Music have announced the release of Grapher, a plug-in which allows users to turn any device with a web browser into a dedicated spectrum analyser display.

The plug-in can be inserted on a track in the user’s DAW, where it establishes a connection and provides a QR code that can be scanned on tablets and mobile devices, as well as an address which can be typed into a web browser. Both the QR code and address link to a web-based application, where users are able to view a spectrum analyser display driven by information streamed from the DAW plug-in using their local network.

Options are available within the web application to configure the size of the display, as well as select different averaging times, and zoom in on specific frequency ranges. Up to four configurations can be saved as presets, and users are able to switch between them with the press of a button.

Sheaf Music say that Grapher’s stability and latency performance depends on a combination of a user’s network setup, DAW, and device model. With that in mind, they offer a free trial version that full functionality with occasional display interruptions to allow potential customers to test the plug-in with their particular setup before purchasing a licence

The company also point out that should browsers start to require HTTPS for any of the features utilised by the web application, that would cause Grapher to stop working.


Grapher is supported on Mac and Windows platforms, and is available in VST3 and AU plug-in formats.
