I'm working on a project where I will be sampling audio into G.711 (mono 8 kHz x 8 bps) format on one ESP8266 and streaming it to another ESP8266 where it will be reconstructed and played out on a speaker.
Has anyone had any success on sending and receiving G.711 audio using an ESP8266? The audio bandwidth is low enough and the ESP8266 is fast enough that I'm thinking that the ESP8266 might be able to do it natively as compared to using a codec. But maybe not...?
Any suggestions on if it can/should be done natively? If not, any suggestions on a low-cost audio codec that I could use?
Thank you for your time.
