Picture Audio Maker is a free multimedia Android application developed by John.P.Eagle. The app allows users to create video files with a still picture and audio. It offers three main features, including recording audio and generating a video file with the user's chosen picture, adding a picture with a title to an existing audio file, and replacing the original video with a still picture while keeping the original audio.

The app is useful for various purposes, such as sharing voice recordings to groups on messaging apps like WeChat, WhatsApp, and Telegram, compressing large music videos into smaller PicAudio files, adding covers to music audio and sharing it as a video to friends, cropping audio and video files into pieces, and recording audio and sharing it as a video.

The app supports all kinds of video and audio formats, such as mp3, wav, aac, amr, mp4, 3gp, m4v, m4a, avi, and more. It converts the file into a standard mp4 (h264 + aac) video file. The app doesn't collect any personal or device data, but Google Analytics may collect app usage data for quality improvement purposes only.
