Hello All I have successfully run the Opus Decoder for 16-bit WAV files. However when doing the same on 8-bit, the decoder produces noise, but on 16 bit data the output is working. Both the 8 and 16 bit files are from the same source and hence except for some loss of quality on 8 bit, they are identical in total play back duration. For both 8 and 16 bit data I have used the following parameters

Hi I am trying to use opus for encoding AES (spdif) stream . I suppose that input samples should be 16 bits in opus but samples in AES stream can be at most 24 bits. Can opus accepts samples more than 16 bits without any modifications in source codes ? If answer is No then "How can I modify opus to accept these 24 bits samples ?"

...is dividing by ui8ScaleFactor = 1 here. OPUS_SET_LSB_DEPTH works as a precision hint to the encoder about where to set the noise floor, but opus_decode still returns 16 bit samples. It always returns 16 bit samples, regardless of whether the original input as 8 bit, 16 bit or 24 bit precision (from opus_encode_float). To actually output 8-bit wav, you have to keep track of this out-of-band and truncate each sample before writing it out. Likewise opus_encode() takes 16 bit samples, so you need to extend each sample from an 8 bit source before encoding. HTH, -r

Hello, sorry for bothering you for such a question but I have been looking for days...   I would like to use opus in a Windows CodeBlocks project but I have a "undefined reference" error for "opus_encode_float", I tried to put all headers and libraries in the right CodeBlocks location but I can't make it run.   Could someone help me please by describing what files from library do I have to use ?   Thank you -------------- next part -------------- An HTML attachment was scrubbed...
