* lavfi/af_aemphasis: remove unnecessary complex number usageGanesh Ajjanagadde2015-12-23
| | | | | | | | | | | | | complex is not available on all platforms. Furthermore, it is trivial to rewrite complex number expressions to real arithmetic, and in fact sometimes advantageous for performance reasons: by wrapping as a complex, one forces a particular Cartesian representation that is not necessarily optimal for the purpose. Configure dependencies also removed, and aemphasis is now available across all platforms. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
