That really depends on your actual use case. Just call Recorder.record() repeatedly until you press your key. There is no magic to it.

with soundcard.default_microphone().recorder() as rec:
    while True:
        data = rec.record()
        if key_has_been_pressed():
            break

yes, I have solved that problem, but sometimes it shows the following problem:
Assertion 's' failed at pulse/stream.c:1411, function pa_stream_connect_record(). Aborting.

why?

my code here:

sounds = []
while True:
    sounds.clear()
    with rec.recorder(samplerate=48000) as mic:
        while keyboard.is_pressed('r'):
            sound = mic.record()
            sounds.append(sound)

Please post a complete, executable example, and a complete stack trace.
