Just before starting the process of manufacture I needed to convert my MP3 file to WAV to make sure I did not have any problems during rendering. One problem with my audio was that it cuts in and cuts off quite abruptly. As my animation will start straight away the audio is okay to abruptly start, however at the end I wanted the image and the text to zoom out and fade out so the end of the audio needs to get quieter. I did this in After Effect this could’ve been done in loads of other programs but I used After Effects as I was already in there and I could see when the audio would be best to get quieter due to the animation. Please find below for a screenshot of my key frames to lower the audio level at the end, to soften it out.
