Sounddevice eats up all my memory about python-sounddevice HOT 7 CLOSED

It works perfectly.

Thanks for the report!

I can confirm that your script keeps growing its memory usage.
When I tried it, it started around 30 MB and reached 250 MB at the end of the script.

I have no clue why this happens ...

Did you try it with Python 3?

When I tried it with Python 3 (after replacing the print statements with print() function calls), the memory consumption grew in the beginning, but then it stayed slightly below 70 MB.
This is obviously better, but probably it should still be less ...

I don't know if there is anything I can do, any ideas?

@Plecto123 Any news on this?

Hey @Plecto123, how did you solved this problem. Now i am also facing same issue in my case memory is going upto 3.1 GB and program is getting stopped.

my os is Ubuntu 18.04
python is 2.7

There have been some improvements in the latest CFFI release 1.12: https://cffi.readthedocs.io/en/latest/whatsnew.html#v1-12.

The script on the top of this page now still has growing memory usage, but in total it only needed 84 MB with python2 and about the same with python3.

@Plecto123 and @venkat-kittu Does that improve your situation?

from python-sounddevice.

I suggest such a solution:

In the 'stop ()' function of 'sounddevice.py' (319th line) add two lines at the end of the 'if' statement:
_last_callback.data = None
_last_callback.out = None

This frees up the memory used by the 'numpy' object.

Thanks @catchanus for the hint, I've implemented it in #250.

Can you (and @Plecto123 and @venkat-kittu) please check if that works for you?
