- A visual guitar tuner
- 17 May 2019 04:27:06 am Permalink
visual-tuner is a simple program for tuning a guitar using an oscilloscope display.
It captures audio and displays a waveform with the horizontal scan frequency matching that of the tuned note.
When the string is tuned correctly, the display remains stationary, otherwise it drifts to a side depending whether the frequency is lower or higher than the one aimed for.
The application is written in C and uses the SDL library for display and audio capture.
