the-amazing-audio-engine

I'm using two third party tools in my project. One is "The Amazing Audio Engine" . I use this for audio filters. The other is GPUImage, or more specifically, GPUImageMovieWriter . When I record videos, I merge an audio recording with the video. This works fine. However, sometimes I do not use The Amazing Audio Engine and just record a normal video using GPUImageMovieWriter. The problem is, even just after initializing The Amazing Audio Engine, the video has only a fraction of a second of audio at the beginning, and then the audio is gone. + (STAudioManager *)sharedManager { static
