Instead of uploading them from your phone, I suggest you record them on your phone and copy it over to your computer to speed it up, you can then open multiple tabs and upload them simultaneously.
I used this Android App, and set the quality to 44100hz: https://play.google.com/store/apps/details?id=com.mawges.hipxel.wav.recorder&hl=en
I also recommend you record using Audacity and set it to 44100hz as well. http://www.audacityteam.org/download/
Makes it a lot quicker to upload than to screw around with the flash recording app.
