Tested environment (Emulator? Real Device?)

Emulator and Real Device

Steps to reproduce the behavior

When I call: path = await flutterSound.startRecorder(filename);

[haideraltahan]

I think I found the problem under flutter_sound/android/src/main/java/com/dooboolab/fluttersound/AudioInterface.java int sampleRate needs to be double rather than int.

Or in flutter_sound/lib/flutter_sound.dart change double sampleRate = 44100.0 to int sampleRate = 44100
