STM32 Audio codec Search and download STM32 Audio codec open source project / source codes from CodeForge. 5 The SAI contains two independent audio sub-blocks. Concepts Before introducing all the Speex features, here are some con cepts in speech coding that help better understand the rest of the manual. audio codecs assessed in our test scenarios: the x-axis displays the three test scenarios divided into groups, the logarithmic y-axis shows the required bitrate in kbit/s We used only public licensed audio codecs and moreover only lossy audio codecs because they have better compression rates with nearly constant quality. The purpose of this article is to: list the audio codec hardware components that might be integrated in the different STM32MPU boards; link these components to the corresponding software framework(s). Optimised for the STM32 family, which is based around ARM's Cortex-M3 core, and aimed at portable and home-audio products, "the STM32 Spirit Audio Engine delivers advantages such as a high-quality codec, rich audio-system features, low memory usage, long battery life and full technical support", said ST.
