You have sent this question to the list of the developers of the Speex speech/audio codec. Speex itself works in the PCM domain, so input/output is well suited to ADCs/DACs. The rest of your question is not a Speex question, but a generic audio electronics question. I suggest you look for generic audio electronics sources for answers. 2011.10.25. 15:33 keltezéssel, David Wyskiel - Wyskiel Tech írta: > I am using ST micro's STM32F103 chip with their AN2812 development > code.
