okay bestie, welcome to the fsl_asrc_sel_proc(9) page — straight out of the Kernel API Manual, and yes it's exactly as niche and iconic as it sounds 🎀

🌸 NAME 🌸

fsl_asrc_sel_proc — literally just picks out your pre-processing and post-processing options for you, no cap 🫶

---

🦋 SYNOPSIS 🦋

void fsl_asrc_sel_proc (int inrate , int outrate , int *pre_proc , int *post_proc );

---

🍓 ARGUMENTS 🍓

• inrate — the input sample rate, like where the audio is coming from 💖
• outrate — the output sample rate, where it's headed ✨
• pre_proc — the return value for the pre-processing option, she's an out-param 💅
• post_proc — the return value for the post-processing option, also an out-param, also thriving 🌈

---

🔥 DESCRIPTION 🔥

so before you even think about calling this function, you gotta make sure you've excluded the following unsupported cases, fr fr. like, do the vibe check first, girlies 🙈

1. inrate > 8.125 * outrate
2. inrate > 16.125 * outrate

⚠️ bestie please actually check these first — the manpage says "make sure to exclude" and it means it. these are the unsupported cases, and skipping the check is not the slay you think it is 💀
