Google Colab (on Chrome) Not Working? #96

Open davies-w opened 1 year ago

davies-w commented 1 year ago

Hi,

I'm really excited to play with this, however, I don't seem to be able to get it to work with Google Colab. I cribbed the Getting Started Example, and it has literally played only once - and despite restarting everything, I haven't been able to get it to work since.

Any help gratefully received! Winton

Hi @wantondevious, thanks for the feedback!

I'm not using Google Colab so unfortunately I'm afraid I cannot help much on this right now. I wouldn't be surprised if there are some limitations in the Colab widget implementation such that you wont hear any sound.

(PS: 100 is painfully high for the volume value, better is something between -inf and 0)

One thing I'm not sure is whether the security model used in Colab is compatible with Tonejs. I suspect it wouldn't work out of the box: IIUC Colab outputs are each isolated in an iframe with different origin (https://stackoverflow.com/a/48920438) while Tonejs use a globally defined audio context (via the web audio API).

Thanks so much Ben! It's such a cool project, I hope I can figure it out, the implications for being able to combine data science and music generation are amazing - your world animation for example!
