[music-dsp] Blend two audio

2018-06-16 Thread Benny Alexandar
Hi, I'm looking for an algorithm to blend two audio. My requirement is given tow identical audio inputs say A1 & A2. A1 is ahead of A2 by t sec, when switch from A1 to A2 it should be seamless and vice versa. -ben ___ dupswapdrop: music-dsp mailing
