AVC Hd Video to AU Audio conversion is the process of extracting and re-encoding the audio track from an MTS file (AVC/H.264 HD video commonly produced by AVCHD camcorders) into the AU audio container format. This converts the high-definition video file into a standalone audio file, suitable for editing, archiving, or playback on audio-focused devices and software.

MTS files typically use the video/MP2T MIME type and store MPEG-2 Transport Stream video and audio data, often encoded with AVC/H.264 codecs. AU files use the audio/basic MIME type and commonly contain uncompressed PCM audio or mu-law encoded data, making them compatible with various audio editing tools and platforms. The conversion process extracts and re-encodes the audio stream from the MTS container into AU format.
The AU Audio (.AU) format is commonly used for video. Understanding its characteristics can be helpful when converting to or from other formats like AVC Hd Video.
While specific technical details aren't available here, AU Audio files generally serve the purpose of storing video effectively within their domain.

Perfect for users seeking a simple, no-installation solution to extract audio from MTS files or convert video recordings into AU audio tracks for editing, playback, or archiving.
AVC Hd Video (MTS) files store high-definition video and audio streams, making them ideal for recording detailed visual content. In contrast, AU Audio files focus solely on audio data, commonly used for audio editing and playback in specific applications. Converting MTS to AU strips out the video component, providing a lightweight audio-only file suitable for sound-focused tasks.
Keep individual source files under 250 MB for free web-based converters to ensure reliable uploads; consider splitting large MTS files before converting.
To preserve audio quality, export AU with a sample rate matching the source (commonly 48 kHz for AVCHD) and use 16- or 24-bit PCM rather than compressed μ-law/A-law when possible.
For batch conversion, use a desktop app or a converter that supports queueing to process multiple MTS files to AU without manual intervention.
Be aware that converting to AU removes all video data; any metadata tied to the video stream (chapter markers, subtitles) may not transfer to the AU audio file.
