Guitar Chord Recognition Algorithm?

阅读更多关于 Guitar Chord Recognition Algorithm?

问题 Whats a good digital signal processing algorithm that is good on guitar chords? Since Fast Fourier Transform I think only is accurate on single notes played on the guitar but not notes that are played simultaenously (i.e. chords). Thanks! 回答1: The short answer is that you need much more than one algorithm. Good chord recognition methods could more aptly be described as "systems", but usually they are indeed based on an initial transform to the frequency domain (most often DFT). If you want a

Java midi note to string mapping via octave of a note

阅读更多关于 Java midi note to string mapping via octave of a note

问题 In my project I want to be able to at least inform the user what string the note they need to play is on. I can get the note and its octave but as I've discovered, that note and its octave can appear in multiple places on a guitar fret board. So my question is: Is there anyway to map a midi note to a guitar string? 回答1: Here's code that takes the MIDI note value and returns the position on the guitar fretboard closest to the end of the instrument. Fret zero is an open string. static class

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 6 years ago . I'm very new at Python but really interested in making a code that could simulate guitar strings. How would I go about doing this? Or at least how would I begin to do this? Any help is appreciated! Thank you! EDIT: I would like to see the sound waves when playing different strings

How to get the fundamental frequency from FFT?

阅读更多关于 How to get the fundamental frequency from FFT?

问题 I am developing a flash guitar, and the only apparent method to discover the frequency of the mic's data looks to be using FFT. Nevertheless, after something like 30 hours of research I could not discover the best way to do that. Should I use Harmonic Product Spectrum (HPS), Cepstrum or Maximum Likelihood? The tuner will have to show frequencys from 25 to 3000Hz. Also, if someone knows about some open source code ready to find the fundamental frequency, please tell me. I can translate it to

Reading Guitar Pro files

阅读更多关于 Reading Guitar Pro files

问题 I was wondering if anybody had heard of a library, preferably a .NET assembly, but Java will do as wel, that allows you to read the data in a Guitar Pro file (.gp3-gp4-gp5) I have this gigantor of a folder with about 50.000 song files, and would really love to write something that can actually archive all these files, for easier searching. And basic information like the tuning of the instruments in the song would be very useful parameters to retrieve from the file and add to the database. I

Thank you! EDIT: I would like to see the sound waves when playing different strings, notes, etc. I am also interested in the sound waves when two different strings are being played, and how that changes when they are dissonant and consonant notes. Another thing I'm interested in is how sometimes strings vibrate when they are not being plucked (resonance). Any help is appreciated, thank you!!! This
