ChordGenPlay

• Take an arbitrary combination of audio files (eg: chords)
• Write down a simple line defining it (eg: "g*3;a*4;am"). Or leave it blank if you want randomness.
• Have generated audio :)

Why?

• Experiment with audio
• Use it if you want to fast track your creative process
• Interested in deep learning with audio?? Generate infinite data (yayyy)
• Maybe make cool sound effects just by the power of script

What can this bad boy do?

• Mini language of sorts to define any arbitrary audio pattern
• Repeat an many times as you want by adding a * (eg: g*3 will repeat g.wav 3 times)
• You get one track at the end with the entire combinations. Repeated or whatever you want
• Generate n clips
• Generate n random clips from the audio. (customize the randomgen function if you need it)
• Batch generator / randomness (Cuz Deep Learning4life)

How do I use this madness?

• Get python
• Install librosa, numpy, scipy, tqdm. (I will be adding a requirements.txt soon)
• Make a folder called music/ pass your folder as an argument
• Rename your audio files to usable ones. (eg: a.wav, g.wav). This is not required but it will save you typing
• python3 runner.py --dir "music/" --rate 22040 --order "g3;a2" --fname "outputs" --random 0 --n 10

Supported parameters

python3 runner.py --dir "music/" --rate 22040 --order "g*3;a*2;a+*5" --fname "outputs" --random 1 --n 20 --rep 3 --maxlen 10

1. "-d", "--dir" : Choose the folder to take the music from
2. "-r", "--rate" : Rate of audio generated
3. "-o", "--order" : File order and repetition
4. "-f", "--fname" : Output file name
5. "-ran", "--random" : 1 or 0 => Randomly pick audio/ shuffle given order or preserve order
6. "-n", "--number" : How many audio files you want
7. "-m", "--rep" : How many times should each file be repeated (maximum)
8. "-l", "--maxlen" : Maximum audio size . Aka max number of files picked

Examples

1. Generate 20 songs with random combinations from the file and repeat each audio a maximum of 3 times. Max length should be 10

python3 runner.py --dir "music/" --rate 22040 --order "g*3;a*2;a+*5" --fname "outputs" --random 1 --n 20 --rep 3 --maxlen 10

Future plans (Contributions welcome :))

• Repeat entire sequences. (Code done. Have to think of a syntax)
