Issue with custom sample rate, audio length increased.

https://www.webrtc-experiment.com/msr/audio-recorder.html I have set sample rate to 11025 and recorded 5 seconds audio then click save button; Wav file length is 20 second now.

mediaRecorder.sampleRate = 11025; mediaRecorder.recorderType = StereoAudioRecorder; mediaRecorder.mimeType = 'audio/wav';
