I have tested the same recording (the music in the attached file) with some sound recording apps on the market, and they record in a perfect way, without noises at all - how is it done? Is it a setting I should set (I use AudioRecord)? Should I manually filter those noises with some algorithm? What should I be looking for?

推荐答案

我觉得44100Hz太多为您的手机功能，而在一般情况下，所有手机的功能：手机不是HI-FI。
结果
试着用8000Hz的。
结果
然后，直到找到一个可接受的录音质量可以改变这个值。

I think 44100Hz is too much for your phone capability, and in general, for all phones capabilities: mobile phones are not HI-FI.
Try with 8000Hz.
Then you can change this value until you find an acceptable recording quality.
