나는 pulseaudio와 jack을 동시에 실행할 수 있도록 pulseaudio-jack-module과 함께 jackd와 pulseaudio를 사용합니다. 웹 브라우징과 몇 가지 다른 앱 외에도 저는 주로 jack 앱을 사용합니다.
오디오를 녹음하려고 하는데 오디오를 녹음하려고 하면 피드백이 정말 안 좋습니다. 헤드폰을 꽂으면 피드백이 대부분 사라지는데, 노트북을 터치하면 녹음에서 들을 수 있어요.
리눅스가 여전히 내 내장 마이크를 통해 녹음하고 있는 것 같습니다. 이 문제를 해결할 수 있는지, 아니면 USB 마이크 같은 것을 구입해야 하는지 궁금합니다.
kxstudio의 오디오를 사용하고 있습니다

저는 단지 음악이나 다른 것이 아닌 음성 해설과 같은 짧은 것을 녹음할 수 있기를 원했습니다.
QAS 블렌더가 있어요
위 스크린샷에서는 귀가 터지지 않도록 헤드폰을 꽂아두었습니다.
저는 이 샘플 클립을 만들었습니다. 짧지만 제가 키를 누르는 소리와 제가 손을 움직이거나 타이핑하는 소리를 들을 수 있습니다. 당신은 할 수10초짜리 영상을 들으시려면 여기를 클릭하세요
그러면 USB 마이크가 필요하다는 뜻입니까, 아니면 오디오 설정에 문제가 있다는 의미입니까? 이 문제를 어떻게 해결할 수 있나요?
답변1
마이크 게인을 늘리면 소음이 더 눈에 띄게 됩니다.
또한 활성 마이크가 너무 많을 수도 있습니다. 각 캡처 옵션을 체계적으로 살펴보고 음소거한 다음 실제로 어떤 옵션이 사용되고 있는지 확인할 때까지 하나씩 음소거를 해제해야 합니다.
