You have sent this question to the list of the developers of the
Speex speech/audio codec.<br>
<br>
Speex itself works in the PCM domain, so input/output is well suited
to ADCs/DACs.<br>
<br>
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.<br>

<div>I am using ST micro's STM32F103 chip with their AN2812
development code. It uses a PWM output, resulting in
low-quality sound. Can I just use a scaled version of the PWM
to drive a DAC? (i.e. is the output linear, or is there shaping
to make the PWM output work?)</div>

<div>Any feedback, links or pointers would be greatly appreciated.</div>
