non-exclusive access for alsa

[maniac0r]

Please would it be possible to allow other applications still use the same microphone when soundmeter is running
Currently it seems it's having exclusive access to audio input it's working on:

arecord -f S16_LE -d 20 -r 44100 -D hw:1,0 /dev/shm/test2.wav
arecord: main:828: audio open error: Device or resource busy

When I stop soundmeter , acrecord works just fine.
