Polyphonic Pitch Detection for Classical Guitar Using the Julia Programming Language

Research paper is available at the root directory.

==================================

What is wav2notes?

• wav2notes is a project designed to help people determine musical notes from classical guitar audio
• Can't identify musical notes by ear? Do not worry, wav2notes has your back!
• Currently can extract musical notes from chords and arpeggios.
• Does not miss any musical notes, false positives are generally easily identifiable by the end user.
• Fast, simple algorithmic approach developed by analysing the sound signature of the classical guitar ==================================

Getting started:

Running the program:

• Tested with the Julia Programming Language v1.8.5 / No problems should occur on other modern versions of Julia
• Install the DSP, Plots, OffsetArrays and Wav packages.
• Navigate to the /src directory in your terminal.
• Open the test.jl file and go to the bottom after reading the comments on top of the main function.
• Modify the example function call for your needs.

Reporting issues:

• Discord @faradaykafesi
• Open an issue with the steps and environment to reproduce the issue.

Future:

• Increasing the precision of the algorithm.
• Support for 6+ String classical guitars.
• Prettier output for the user.
• Possibly a version written in Rust to compile to WASM and run in a browser. Using the crate RFFT.rs which is a wrapper for the FFTW3 Rust library, increasing the performance 2x for any real input.
