 Replying to [comment:1 cehoyos]:
 > Does the !SonicStage encoder support float-in-wav input as produced with
 `ffmpeg -i input -acodec pcm_f32le out.wav`?

 No, it doesn't. It will show the following error message.

 The following files cannot be converted to ATRAC Advanced Lossless.
 Only WAV (16bit 44.1kHz 2ch) tracks can be compressed to ATRAC Advanced
 Lossless format.
