Hello! Is there any way to transmit audio from microphone to IP camera (Axis) using Wowza and Flash? ---

Maybe. This [document links to Axis Audio API](http://www.axis.com/techsup/cam_servers/dev/cam_http_api_index.php) > Audio API > > Supported from firmware 5.00 > > This document explains the basic arguments and parameters to **send** , receive and configure an audio stream using HTTP or **RTSP** requests. So, it seems conceivable that you could use [Wowza PushPublish](https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing%28Push-Publishing%29) in some way. I am not sure. Richard ---

Hi, Please can you rephrase the question. I assume you’re wanting to inject audio into a stream Wowza is receiving from an IP camera which does not have an audio track. When playback clients play the IP camera stream from Wowza, you want this stream to have audio and video? If so, please see the following article - [Adding An Audio Track To A Video-Only Stream (ModuleAddAudioTrack)](https://www.wowza.com/docs/how-to-add-an-audio-track-to-a-video-only-stream-moduleaddaudiotrack%28ModuleAddAudioTrack%29) Jason ---

Hi It depends on the codec the camera supports and what Flash can generate to match. I think it’s possible if the codec supported is MP3 or AAC on the camera. This would require custom work on your part. If required you can post in the [Find a consultant forum](http://community.wowza.com/c/-/7) or email support@wowza.com requesting the independent consultants list. Jason ---

No, i just want to send audio from microphone to IP camera with loud speakers. ![](http://www.axis.com/techsup/cam_servers/cam_2191/img/simplextalk.jpg) In Audio API manual of Axis cameras is written that i need to send audio data by http to http:///axis-cgi/audio/transmit.cgi. Like this: > POST /axis-cgi/audio/transmit.cgi HTTP/1.0 > > Content-Type: audio/basic > > Content-Length: 9999999 > > Connection: Keep-Alive > > Cache-Control: no-cache > > Authorization: Basic cm9vdDpwYXNz Is it possible to create audio stream on Flash client, and forward it to Axis camera using Wowza?
