title: Resample 8KHz audio sample rate to 44.1KHz using swr_convert[FFMPEG]
body: <p>Anybody, has tried upsampling audio stream from 8K to 44.1K?</p>
  
  <p>I need to resample input audio stream 8KHz to 44.1K since Mac OSX default audio output device support minimum 44.1K audio sampling rate.</p>
  
  <p>I tried to up-sampling using FFMPEG swr_convert() API, it converts with lots of noise. Which is not good.
  If anybody has tried successfully upscale 8K to 44.1 or 48K then please share it.</p>
  
  <p>Solution with C/C++ library code is preferable. Didn't tried Core-audio samples.</p>
  
  <p>I Tried swr_convert() code from following link <a href="https://www.ffmpeg.org/doxygen/2.1/group__lswr.html#details" rel="nofollow">https://www.ffmpeg.org/doxygen/2.1/group__lswr.html#details</a></p>
  
  <p>Thanks,
  Ramanand    </p>
