Also you need to pay royalties to someone for MP3 decode, something like $0.25 I would think only applied to commercial use.

Great job ! Thank You !

Running fine on esp-12 module, without extra RAM and without i2s DAC. Reasonable sound quality with simple low-pass filter and audio-amp.

I use it to listen my favourite radio station. I have some ideas to improve it :

- Add a little piece of code to drive SSD1306 oled display and display song title.
- Add a way to choose between pre-configured WiFi AP. The easiest way is to scan APs and compare SSIDs with a local list.
- Add Stereo decoding

This is an useful application. For instance, it is possible to fit this device into an old tube radio to make it receiving more and more Internet radio stations.

Thank you again for this nice code and hope someone will improve it

Thank you again for this nice code and hope someone will improve it

Heh, I'm planning on maybe improving the PWM output a bit (something with delta-sigma instead of PWM sounds good) but apart from that, I'll leave other improvements to the community. I'm open to Git pull requests if people develop something everyone can enjoy.
