similar to: OPUS on cortex M4

Thanks for the reply. For my application I unfortunately need a better signal reconstruction. It's not necessarily a problem that the constant DC voltage is removed, but the audio signal will need to be more exact because it's also studied visually. To be more exact, I need to record and transmit audio data recorded from animals (mostly birds). Are there ways to achieve a more similar

Am I supposed to take an "INFORMATIVE" document as standard? How can one know the output channel order if there is no standard way to map it on creation? Being undefined, it's up to the decoders to decide the channel order, leading to incompatibility among implementations.

OK Martin. Thank you for the explanations and for your time. I am writing a program that reads and writes all existent Tags types. It lacks only to end the edition (rewriting) of "Native" Flac and Matroska. Both cases for the same problem: the separation of Tags and Picture in different blocks. In Flac I resolved it, but now I have to add METADATA_BLOCK_PICTURE. Reading Vorbis

You said "With the exception of where to put a picture file, VorbisComments in a Vorbis stream are the same as VorbisComments in a FLAC stream." In METADATA_BLOCK_PICTURE case they would not be the same. Up to now we could exchange the complete block of VorbisComments. But with the addiction of METADATA_BLOCK_PICTURE doesn't happen this way. In Ogg files the METADATA_BLOCK_PICTURE
