2017-10-16 | Added correlation function which updated array in place | Justin Worthe | |
2017-10-16 | Added 'brew update' to travisci macos build script | Justin Worthe | |
There's currently an error in the build on installing the dependencies from homebrew. From the comments here https://github.com/Homebrew/brew/issues/3299, looks like this might solve it. | |||
2017-10-15 | Added emscripten calls for hz interpretation | Justin Worthe | |
This also uncovered a weird compilation issue. Emscripten did NOT like me using the remainder operator with a floating point number. | |||
2017-10-15 | Moved emscripten APIs to their own module and added stubs for other methods | Justin Worthe | |
2017-09-24 | Updated readme to include info a WASM build | Justin Worthe | |
2017-09-24 | Emscripten endpoint for finding fundamental frequency | Justin Worthe | |
IT'S ALIVE! | |||
2017-09-24 | Cleaned up transforms api | Justin Worthe | |
- made things that didn't need to be public hidden - renamed find fundamental function to remove correlation (there isn't an alternative anymore) | |||
2017-09-18 | Updated readme to include upcoming features plan | Justin Worthe | |
2017-09-10 | Merge branch 'master' of github.com:JWorthe/rusty_microphone | Justin Worthe | |
2017-09-10 | Removed unnecessary rounding of error | Justin Worthe | |
2017-09-10 | Added compile flags to disable anything that shouldn't end in a wasm build | Justin Worthe | |
- No GTK - No Portaudio | |||
2017-08-12 | Fixed potential index out of bounds error | Justin Worthe | |
2017-08-12 | Merge branch 'master' of github.com:JWorthe/rusty_microphone | Justin Worthe | |
2017-08-12 | Added missing requirement for Mac build process | Justin Worthe | |
2017-08-02 | Readded frame skipping | Justin Worthe | |
This was becoming an issue on debug builds on the laptop. Really, it's for the best to skip frames rather than getting stuck in a perpetual time delay. | |||
2017-08-02 | Added installation needed for base Fedora install | Justin Worthe | |
2017-08-02 | Made OSX travis build required and updated readme to reflect requirements | Justin Worthe | |
2017-08-02 | Added missing portaudio dependency to MacOS build | Justin Worthe | |
Looks like the portaudio automagical download and build only works on Linux :( | |||
2017-08-02 | Updated sharp/flat characters to use correct unicode | Justin Worthe | |
2017-08-02 | Removed unnecessary comment | Justin Worthe | |
2017-08-02 | Experimenting with adding OSX travis build | Justin Worthe | |
2017-07-22 | Fixed incorrect type inferrence to a vector rather than a slice | Justin Worthe | |
2017-07-21 | Made changes suggested by Clippy | Justin Worthe | |
2017-07-15 | Decreased window size and increased framerate | Justin Worthe | |
The samller windows size has a few effects: 1. the frequency calculation will be less accurate, because less iterations of the binary search will be effective. 2. 'mixed signals', measures at the start or end of a note where half the signal is one thing and the other half is something else will have less impact, since they will be on the screen for less time. The higher frame rate also looks really nice. | |||
2017-07-12 | Simplified loop for doing calculations from microphone samples | Justin Worthe | |
In the benchmarks, the correlation can be done in 0.5ms. I'm only expecting new samples from the microphone every 23ms at best. I don't need to worry about dropping frames at this point. | |||
2017-07-12 | Added benchmark for finding fundamental with correlation | Justin Worthe | |
2017-07-11 | Updated silence level and made no pitch's error show a 'perfect' pitch ↵ | Justin Worthe | |
background | |||
2017-07-08 | Ignored audio device unit tests because Travis doesn't have audio devices | Justin Worthe | |
2017-07-08 | Attempt to enable dummy sound device on travis | Justin Worthe | |
It's not clear online on if this will actually work or if it's disabled on Travis. It definitely was disabled in 2014, according to this issue https://github.com/travis-ci/travis-ci/issues/1754, but the comments at the bottom imply it may work now. | |||
2017-07-08 | Refactoring of code to be more functional | Justin Worthe | |
If tests break on travis after this, it's because I reenabled some portaudio tests. I'm not sure if travis actually has sound available on their build servers. | |||
2017-07-06 | Updated readme to indicate lack of Windows support | Justin Worthe | |
2017-07-05 | Started listening on default microphone on startup | Justin Worthe | |
2017-07-04 | Removed bad unwraps | Justin Worthe | |
2017-07-03 | Hid correlation chart by default | Justin Worthe | |
2017-07-03 | Added TravisCI badge | Justin Worthe | |
2017-07-03 | Updated tests to match new label format | Justin Worthe | |
2017-07-03 | Updated readme | Justin Worthe | |
2017-07-03 | Removed FFT chart | Justin Worthe | |
I was only using the correlation anyway, so this simplifies a bit | |||
2017-07-03 | Added silence and noise detection | Justin Worthe | |
Also updated GUI to present note and error in a friendlier way | |||
2017-06-27 | Added binary search to refine fundamental frequency search on the correlation | Justin Worthe | |
It first finds the max peak. Then, to increase the resolution, it works out how that peak lines up with the other peaks and nudges it a bit up or down. | |||
2017-06-26 | Added function for linear interpolation | Justin Worthe | |
2017-06-26 | Increased number of samples | Justin Worthe | |
2017-06-25 | Added fundamental frequency to correlation graph and fixed zeroing of it | Justin Worthe | |
2017-04-19 | Added basic buttons to toggle chart visibility | Justin Worthe | |
The main idea here is to be able to bring focus to specific charts. Also, I learned how to make one chart expand more. | |||
2017-04-18 | Added basic oscilloscope functionality to watch the waveform | Justin Worthe | |
The triggering algorithm isn't great at the moment. Seems the interesting signals end up crossing zero a few times. I need to take things like maxima into account as well. I'm also running out of vertical space. I need to start making the GUI a bit smarter, and allow turning some of these graphs on/off at runtime. | |||
2017-03-25 | Added a graphical indication of the pith's sharpness or flatness | Justin Worthe | |
I'm not 100% happy with the precision of the correlation function at this point. I'm hoping that with a bit more work, I can get it to be more precise, and then the indicator will be more meaningful. | |||
2017-02-21 | Added license | Justin Worthe | |
2017-02-16 | Updated tasks in readme file | Justin Worthe | |
2017-02-16 | Worked to improve performance of debug graphs | Justin Worthe | |
- Moved from channels to shared state - Allowed audio frame skipping | |||
2017-01-17 | Added drawing area for correlation, but hid all graphs | Justin Worthe | |
The current method of sending all that data with channels turns out to be terrible for performance. On the other hand, I need to get the data to the GTK main thread if I want to do anything with it. So I have a conundrum. |
