single channel audio data to mp3 problem

[luciferldy]

I use audio recorder to record a single channel, 16k sample rate audio file.

use this to convert to mp3, only set sampleRate = 8k can get right mp3 file. if it set sample = 16k, mp3 file media duration become short and speech speed fast.

I also encountered the same issue. Could the author please explain why single-channel audio can only be set to a sample rate of 8k?
