I don’t know whether or not this topic has already discussed but if YES then am sorry and need someone to point me to the link.
Am developing an IVR service where caller of the IVR number will have to sing and record their song. My issue is that the while singing the caller should hear an audio track in background and when the song is recorded, the audio track and the song become one (1) song thus one (1) file.
Have anyone out there already done such a setting? If yes, could you please let me know where to start and what are the applications involved?
Thank to all of you for your help
