This is used to support 11WebAudio for Chromium on Android. 12 13Local Modifications: 14Only the FFT routines from the OpenMAX DL package are included. The 15code was modified to work with gcc and a new implementation for a 16floating-point FFT was added. 17 18The original ARM license is unclear, but Google has obtained 19permission to relicense this code under a BSD license. 20

1Bug 1158741 added an omxSP_FFTInv_CCSToR_F32_Sfs_unscaled function as an 2optimization which performs the same operation as 3omxSP_FFTInv_CCSToR_F32_Sfs except it doesn't scale the results by the 4length of the FFT. For consistency with other FFT routines used, it does 5multiply the results by two. 6 7The affected files are: 8media/openmax_dl/dl/sp/api/omxSP.h 9media/openmax_dl/dl/sp/src/omxSP_FFTInv_CCSToR_F32_Sfs_unscaled_s.S 10
