Opus in WebM
...basically an intrinsic aspect of the mathematics. If you seek into the middle of an Opus stream, that's about how long it takes before the audio converges to be correct. I see. Thanks for the info. Any idea about the other Matroska tags? I guess CodecDelay will be the value you get from OPUS_GET_LOOKAHEAD() converted to nanoseconds? DiscardPadding seems to assume that you might top off an opus frame with empty samples when the frame would spill onto the next matroska timestamp. So rather than have continuous opus that could be decoded one after another, you'd have to jump over these little ga...

OPUS on cortex M4 (Nicolas Ehrenberg)
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
