sigrok VS Friture

Just bought a 8ch signal analyzer from sparkfun, but sigrok.org has been down for at least a few days. anyone know if this project is still active? Source: about 2 years ago

You might look at meters supported by https://sigrok.org, and the sigrok project (open source datalogging/instrument control.) At least may serve as a starting list to narrow down to what you need. Source: over 2 years ago

A USB logic analyzer. A Saleae (https://www.saleae.com/) or others that interace to sigrok (https://sigrok.org/ ). The API can be used to automate testing and debugging by accessing onboard registers from your PC. I find it easier to work on a PC than a benchtop logic analyzer - but it depends on the application.

Nice! Have you considered adding support for your LA to sigrok PulseView? It's a great open-source test equipment GUI and you'd get a lot of neat features for free (like protocol decoding). Source: almost 3 years ago

> I can write something about it if there's any interest* That would be great. https://sigrok.org/ has support for basic CO2 monitors, maybe it could be extended to support the sensors you mentioned.. - Source: Hacker News / about 3 years ago

As far as I know, the only more accurate tools for resonance are those that show full spectrograms, for example: In-formant, Friture, and Praat. Source: about 1 year ago

Get a spectrogram like this one: https://friture.org/ (use just one graph the 2d spectrogram, dm me for settings) Try 2 things: first of all breathe into your mic and try to move the lines/groupings of data upwards and downwards by moving your tongue and throat. Then do the same but take a video of white noise (from youtube) on your phone and place the phone speaker against your lips. Move your tongue and throat... Source: about 1 year ago

I got some free audio analysis software here. All I have is a webcam mic, but I'm pretty sure I see something on the spectrogram at 60, 120, and 240 hz. But I'm not sure if I'm going down the wrong path here. Source: over 1 year ago

If what you want is a real spectrum analyzer you'll need to try other software. For something free and open-source like Audacity, try Friture. Source: over 1 year ago

Your main focus should be work on balancing your vocal weight and vocal size and there are no good applications to help with that (there are spectrograms, but it's a rabbit hole - they are very hard to interpret and as practice shows, people do not benefit from spending time on trying to understand how to use them.) Above that, one of the first goals should be for you to learn how to hear the changes in size and... Source: over 1 year ago
