Sounddevice eats up all my memory

Examplecode:

import numpy as np
import time
import sounddevice as sd
 
 
def FindFreq_Resp(f_num, Amp):
    print "Calculating frequency response..."
    Freq=np.logspace(1.3, 4.3, num=f_num)
    for f in Freq:
            xx=np.linspace(0.0, 1, 48000)
            y=Amp*np.sin(f*2.0*np.pi*xx)
            myrecording = sd.playrec(y, 48000, channels=1, blocking=True)        
 
Fs=48000
FindFreq_Resp(100,0.1)
print "Some memory has been eaten"
FindFreq_Resp(100,0.1)
print "Even more memory has been eaten"
FindFreq_Resp(100,0.1)
print "Not much memory left :("

If I run the function FindFreq_Resp enough time, the program will run out of swap memory and freeze indefinitely. Why does this happen?

It works perfectly.

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?
