Question
Is the STM32C55 powerful enough to decode audio?
Hello,
I am making a device which will play encoded audio files from a (Q)SPI flash and I wanted to use the STM32C55 (with its internal DAC). Alas, I haven’t been able to find flash/RAM/CPU frequency requirements for the codecs except for MP3 Helix (https://github.com/liuduanfei/helix), but I would rather use Opus because it has a better bitrate-to-quality ratio.
Does anyone have experience with decoding audio on the STM32C55 (or any similar MCU for that matter)? How much flash and RAM was needed for the decoder?
Thanks.
