Hey, I am searching one encoder with support for 32 bitdepth. https://wiki.hydrogenaud.io/index.php?title=Lossless_comparison#Apple_Lossless_Audio_Codec_.28ALAC.29

ALAC would be good choice but I dont know how decoder audio after encoding (audio.wav | refalac64 -b 32 - -o output.m4a)

What other encoder you would recommend??

Wavpack: https://www.wavpack.com

I don't know any other one.

wavpack work fine but refalac also can do it.

Both can be decoded fine (bitidentical to the source in my test) with ffmpeg (using -acodec pcm_s32le).

Flac in FFmpeg after https://github.com/FFmpeg/FFmpeg/commit/d8f1404c50dfc3e3792b823e97abf56b5c5e9ee2 (it requires -strict experimental).

Official FLAC supports 32 bits integer since version 1.4.0.

Dolby E also by default outputs 32 bit integer, so allows 32 bit flac encoding with -strict experimental
