fsl_easrc_normalize_filter(9)

🌸 NAME 🌸

Bestie, this is the Kernel API Manual page for fsl_easrc_normalize_filter(9) — and it's literally all about scaling filter coefficients (64 bits float). 💅

So here's the vibe: for input float32 normalized range (1.0,-1.0) -> output int[16,24,32]: scale it by multiplying filter coefficients by 2^31. For input int[16, 24, 32] -> output float32 scale it by multiplying filter coefficients by 2^-15, 2^-23, 2^-31 — and the description ends with input: exactly like that. 😭✨

✨ SYNOPSIS ✨

The signature is giving C function, and it returns int:

       int fsl_easrc_normalize_filter (struct fsl_asrc *easrc , u64 *infilter ,
       u64 *outfilter , int shift );

🎀 ARGUMENTS 🎀

• easrc — Structure pointer of fsl_asrc. 🦋
• infilter — Pointer to non-scaled input filter. 💖
• outfilter — scaled filter. 🌸
• shift — The multiply factor output: 👑
