Compiling faad2 on the Android platform

1, download the source code from the official website

2. Edit a config.h:

3, Write Android.mk

4, compile.

5, fixed-point:

The above compiler is floating point, can be compiled to fixed point, the method is to open the Faad/libfaad/common.h two macros:

#define Fixed_point#define big_iq_table

Then rinse the compilation, on my phone, using fixed point, can be 5 times times faster.
