Re: Realtime MP3 encoder 48kHz Stereo

Yes of course, the encoder is called shine mp3 encoder. I started with the fixed point implementation but am abandoning that in favour of single precision floating point after some research and synthetic testing on ESP32 show that asm optimisation should be much faster using the FPU. The FPU instruc...

Realtime MP3 encoder 48kHz Stereo

I have ported and optimised an MP3 compliant encoder to ESP32, just wondering if anyone is interested in the project. If so I will clean up the code and post it here. Current status: Encodes @48000Hz 16bit Stereo using between 37-43% on one core depending on where you choose to place buffers and tab...
