If you are looking for a reliable and easy-to-use audio-video converter for Windows, I recommend Softaken Audio Video Converter software.It supports a wide range of audio formats, such as MP3, WAV, OGG, FLAC, etc., and video formats, such as MOV, MP4, MKV, FLV, etc. The software allows batch conversion, so users can convert single and multiple files at once; it saves time and effort. The user can set the quality of audio and video in bitrate, resolution, and codec to preserve original quality. It provides a real-time preview before conversion and supports smart duplicate handling. This application works on all Windows versions, such as 11, 10, 8, 7, XP, and Vista, and every user can get the free demo version.
