How to run chordino on a batch of audio files

Method 1 - sonic annotator

I'm working on a mac here so I'm assuming you have bash/terminal available. If you're on Windows you could try setting up Windows Subsytem for Linux maybe? (WSL)

• Open a terminal, get the version of sonic-annotator for your OS from here: https://code.soundsoftware.ac.uk/projects/sonic-annotator/files
• Move the downloaded file to your preferred location and extract it (tar -xvf sonic-annotator-1.6-macos.tar.gz was the command I used)
• Open a terminal, then cd to the sonic-annotator-1.6-macos folder that just got created in the last step
• find the name of the chordino plugin like so:

import pretty_midi as pm
import json


def get_syncpoint_downbeat_times(syncpoints):
    downbeat_times = []
    for syncpoint in syncpoints:
        if len(syncpoint) == 2 or syncpoint[2] == 0:
            downbeat_times.append(syncpoint[1])
    return downbeat_times

$ ./chord-parser -c Cmaj7
{
  input: {
    symbol: 'Cmaj7',
    rootNote: 'C',
    descriptor: 'maj7',
    parsableDescriptor: 'maj7',
    modifiers: [ 'add7' ],
    notationSystem: 'english'
  },

Came close with this one but couldn't quite get anything as clear as the original.

Cymbal synthesis tutorial

Dan Stowell



This tutorial describes an approach to synthesising decent-sounding cymbals, in a way that is efficient enough for a real-time synthesis system.
