Research direction
The issue is a user asking why base64 decoded WAV data is not playable in PHP. Investigate the base64 string format; the user is stripping the data URI prefix but may need to ensure the resultant binary is valid WAV. Check the FlashWavRecorder output for proper WAV header and compare with PHP's file put contents. Consider if the issue is with PHP's base64 decoding or missing audio codec support.
