Hi Michael,
Thanks for the reply ..but my problem is slightly different.


I  explain here..
The output.wav file contain both files but play one by one ....Inorder to listen the output file one by one ..I need to play both files (of output files) at a time , that is music file play in background, at same time recorded file play in foreground...(so that it seems a one complete song with (music and recorded user songs)).


and also output files adjusted it duration period (12 sec) according to the duration period of max( music.wav(10 sec), record.wav(12 sec))  not add up of two files.


May be  it is possible...... to play music files in one legs..and at same time record user voice song in other leg and thus produce recorded file have both songs ( because music file play at the same time as recording triggered..) 


actually i have no any idea.....please clarify...it. Or any patching method is there..or we doing some changing  in dialplan with playback or other....?


Thanks again for your reply sir..
Any help will be highly appreciated....

Subject: [Freeswitch-users] Recording with music (playing in background)
To: freeswitch-users@lists.freeswitch.org


 Hi all,

 I am new freeswitch user.

 I need to record the user voice/songs with music that selected earlier 
 and this music plays in background . That is results comes as mix up of both songs
 i.e music in background and voice records in foreground .

 I want to dedicate this mix up file to other user..
 Can I patchup these two files seperately..into one file ? or simultaneouly do recording  
 with playing music in background ......and if so ..then please guide me..how can i do it ?

 Any help will be highly appreciated.

 Thanks .
