Xmos xscope update#
Update 8Mar2022: Message from Digi-Key: The XCORE MICROPHONE ARRAY EVALUATION BOARD XK-USB-MIC-UF216 has changed status to obsoleted ( here). Moved to the Alternatives section, iOS “Sound Recognition”. using TensorFlow). Having discovered the new function on the iPhones, maybe I now only need to listen for one sound only, coming from the iPhone crapped with neural engines, that already is on the bedside table.
Xmos xscope generator#
I had come some way on this (getting a number on the display that increased linearly with a frequency from a tone generator (v0619, 28Feb2022) when I discovered a beautiful new function, starting on the Apple iPhone’s iOS 14.0 (Sep2020, so I am behind, as I am with not having started with the new XMOS.ai processors that have a built-in vector unit, meant for embedded machine learning, by f.ex. I had at first thought that I should listen and recognise several sounds by getting a recording of each of them, do an offline spectrum analysis to find the frequency components, load those spectra over to the Beep-BRRR unit – and then compare each of them with every frequency charts that I (hypothetically) were to make from microphone inputs, on the fly. More precise: pages in that case will not have any collapsed state. However, the search field on the top of this page is global for all notes, (expanding) all containing folds during the search. This text 123456789 will only be found with browser search when the fold is expanded. Should this blog note get too bloated (it already is bloated), I probably will sum up in a new note when I’m finished. No nice Trello boards for spec points with timelines. In other words, this blog note exposes my private development process, where there are no reviews or UML component diagrams, as such. The Contents table may help, though, plus searching in the text. Especially: some problem described early may have a solution further down, which I may not have referenced down or up. Observe Standard disclaimer.Īlso see the stream of consciousness style disclaimer – since I’m afraid the structure is the result of what is happening as I am working on this project, right now.
