vector_fmul_window_scaled: Option<unsafe extern "C" fn(dst: *mut i16, src0: *const i32, src1: *const i32, win: *const i32, len: c_int, bits: u8)>

Overlap/add with window function. Result is scaled down by "bits" bits. Used primarily by MDCT-based audio codecs. Source and destination vectors must overlap exactly or not at all.

@param dst result vector constraints: 16-byte aligned @param src0 first source vector constraints: 16-byte aligned @param src1 second source vector constraints: 16-byte aligned @param win half-window vector constraints: 16-byte aligned @param len length of vector constraints: multiple of 4 @param bits scaling parameter

vector_fmul_window: Option<unsafe extern "C" fn(dst: *mut i32, src0: *const i32, src1: *const i32, win: *const i32, len: c_int)>

Overlap/add with window function. Used primarily by MDCT-based audio codecs. Source and destination vectors must overlap exactly or not at all.

@param dst result vector constraints: 32-byte aligned @param src0 first source vector constraints: 16-byte aligned @param src1 second source vector constraints: 16-byte aligned @param win half-window vector constraints: 16-byte aligned @param len length of vector constraints: multiple of 4
