STRUCT SND_ENC_FLAC(9)

💅 NAME 💅

Okay so bestie, welcome to the struct snd_enc_flac(9) page in the Kernel API Manual — and no cap, this one is all about FLAC encoder parameters ✨. The name is literally struct snd_enc_flac, and its whole main-character job is holding FLAC encoder parameter info. Slay.

---

✨ SYNOPSIS ✨

struct snd_enc_flac {
    __u32 num;
    __u32 gain;
 };

• num — this is the serial number, and it’s valid only for OGG formats. It needs to be set by the application. iykyk 💖
• gain — this one adds replay gain tags. cute, useful, done 🎀

🌸 DESCRIPTION 🌸

These options were extracted from the FLAC online documentation at http://flac.sourceforge.net/documentation_tools_flac.html 📚✨

To make the API simpler, it is assumed that the user will select quality profiles. Additional options that affect encoding quality and speed can be added at a later stage if needed. lowkey sensible, ngl 🦋

By default the Subset format is used by encoders. periodt 💅

TAGS such as pictures, etc, cannot be handled by an offloaded encoder and are not supported in this API. Not me being dramatic, but this is a real limitation — those TAGS are straight-up not supported here 😭
