Record from the microphone indefinitely
Clash Royale CLAN TAG#URR8PPP

I'm working with the application "arecord" (under Arch Linux). I'm want to capture sound from my microphone and save it to the disk.
This is my command:
arecord -f dat -d 2 --channels 1 -D hw:1,0 /tmp/test.wav
This captures a two seconds (-d -> duration) file and then saves it to disk. This basically works.
What I want to do is to record an "infinite" sound track (without fixed duration) and save this track immediately to disk. Without waiting for it to finish. So, if I shut down the machine while recording (or there's a power outage), the sound track will be saved on the disk up to that moment.
Is this possible?

Can't you just omit the-doption? I mean, isn't it the default behaviour ofarecordto run continuously until killed?

What if I want to write a MP3 file (instead of WAV) and still write it to disk as it recording?

Excerpt from the arecord's man page:
-d, --duration=#
Interrupt after # seconds. A value of zero means infinity. The default is zero, so if this option is omitted then the record/play‐
back process will run until it is killed.
This is the command I used to record sound indefinitely with a Kinobo Akiro USB microphone using a sampling rate of 48 kHz:
arecord --device="hw:1,0" --format=S16_LE --rate=48 rec_$(date "+%F_%H-%M-%S").wav
See this answer on how to specify which device to use.
To convert a WAVE file into mp3, you can use ffmpeg:
ffmpeg -i rec.wav -acodec mp3 rec.mp3
