How to Extract AAC Audio from MTS Video
Pull the audio track from any MTS video and save it as a standalone AAC file
Select a MTS video file containing the audio you want to extract. Works with music videos, recorded lectures, podcast recordings, or any video with an audio track. There is no need to install editing software — the entire extraction happens in the cloud.
The audio track is separated from the video frames and encoded as AAC. Video data is discarded cleanly — the resulting file contains only the audio at the selected quality level.
Download your extracted AAC audio file — typically 90% smaller than the original video. Ready for music players, podcast apps, or further editing in any audio workstation. Files are deleted from our servers automatically after processing.
Why Convert MTS to AAC
AAC delivers noticeably better audio quality than MP3 at the same bitrate. At 128 kbps, AAC sounds closer to the original recording than MP3 at 160 kbps, saving space without sacrificing listening quality.
AAC is the default format for Apple Music, iTunes Store purchases, and all Apple devices. iPhone, iPad, Mac, AirPods, and HomePod are all optimized for AAC playback and streaming.
YouTube, Instagram, TikTok, and most social platforms encode audio in AAC. Converting to AAC before uploading ensures your audio matches the platform's native format for optimal quality.
AAC supports up to 48 channels of audio, including 5.1 and 7.1 surround sound configurations. AAC-LC and HE-AAC profiles handle everything from mono voice to immersive cinema audio.
HE-AAC delivers intelligible, pleasant audio even at 32-48 kbps, making it ideal for voice streaming, podcasts over slow connections, and applications where bandwidth is extremely limited.
About the MTS Format
MTS (MPEG Transport Stream) is an AVCHD video file format jointly developed by Sony and Panasonic. It uses the MPEG-2 transport stream container to store H.264/AVC high-definition video along with Dolby Digital or PCM audio. MTS files are the native recording format for many HD camcorders from Sony, Panasonic, Canon, and other manufacturers.
MTS files deliver broadcast-quality HD video at 1080i or 1080p resolution. However, the AVCHD format has limited software compatibility compared to MP4 — many video editors and media players require conversion before the footage can be used. Converting MTS to MP4 preserves the HD quality while making the video universally playable across devices and platforms.
