Axis IP cameras are using VAPIX (open API) to transfer remotelly audio from camera mic over http, and to send audio over http to the integrated camera speaker. The audio is raw stream, encoded with G711 (mulaw encoding).
We need a simple code (library, codec, or utility class with few methods) which will play the streamed audio remotely from the camera mic on Android and iPhone devices; and vice-versa (to send audio from the android/iPhone microphone to Axis camera speaker, over VAPIX API.
The audio must be clear with correct encoding/ no white noise.
It is preferable to apply, if you have already experience with VAPIX and deal with this / similar problem before.
