Unfortunately, not yet. Analog channels are not available in the [Low Level Analyzer SDK](https://github.com/saleae/SampleAnalyzer/blob/master/docs/Analyzer_API.md), so only digital waveforms can be processed by LLAs. The [High Level Analyzer API does provide for analog measurements](https://support.saleae.com/extensions/api-documentation), but as far as I know you can’t get user customization of analog channels on ‘live’ waveform data stream (which only input from [FrameV2 data](https://support.saleae.com/saleae-api-and-sdk/protocol-analyzer-sdk/framev2-hla-support-analyzer-sdk) coming from LLAs), per: > **[Can Custom Analyzers Process Analog Channels?](https://support.saleae.com/faq/technical-faq/can-custom-analyzers-process-analog-channels)** Also, even if you could get the analog channel data – the second issue would be how to display the FFT graphically. Right now, you can’t bind to a GUI framework within the native Saleae plug-in python environment without workaround for adding local extensions of the python environment (e.g., see: [Third party libraries with HLAs - #2 by john](https://discuss.saleae.com/t/third-party-libraries-with-hlas/595/2)). Bottom line: I think there is limited analog channel support with ‘official’ APIs and SDKs at the moment. For now, Analog channel data is only available for text-based metrics on a user-selected ‘range’ of data (i.e., an analog **measurement** type of HLA that runs on a fixed time interval of one channel in a stopped capture). --- _[View the full topic](https://discuss.saleae.com/t/new-feature-request-software-filters/388)._
