How can I extract audio losslessly from a video on my windows 10 pc?

You need a dedicated audio editing app for extracting audio losslessly from a video.

Shutter Encoder is a powerhouse open-source tool that has become a favorite among video editors and tech enthusiasts. Developed by French editor Paul Pacifico, it acts as a user-friendly wrapper for the legendary command-line engine. This means you get professional-grade control over bitrates, codecs, and metadata without ever having to touch a line of code. You can try it out for extracting audio from video losslessly on a Windows 11/10 PC.

What makes it unique is its "Swiss Army Knife" approach. Beyond simple conversions, it can download web videos, burn-in subtitles, and even use AI for vocal separation or transcription. For audio extraction specifically, its "Extract" function is a standout, as it can strip audio from a video file without re-encoding it, preserving the original studio quality and finishing the task in mere seconds.

Cons

Intimidating Interface: The UI is packed with technical parameters and "buttons everywhere," which can be overwhelming if you just want a simple "Convert" button.

Technical Jargon: It uses professional broadcasting terminology (like rewrap, conform, and bitrate) that might require a quick Google search for beginners.

Java Runtime Required: Since it's built on Java, it may feel less "native" on Windows or macOS and requires the Java environment to be present on your system.

Occasional Stability Issues: Because it is an ambitious one-man project wrapping many complex libraries, it can occasionally crash when handling corrupted or extremely rare video containers.

Steep Learning Curve: Accessing its most powerful features, such as "Object Removal" or "Detect Cut," takes significant trial and error compared to simpler apps.

Add your file, and in the output settings, choose the format "Same as source" or a lossless format. It will demux or decode accordingly.

You can use the MKVToolNix GUI to extract audio from video on windows pc.

MKVToolNix GUI is a specialized application primarily designed for creating, manipulating, and inspecting Matroska (MKV) media containers. Its core strength for audio extraction lies in the multiplexer function, which can handle not just MKV files but also common formats like MP4, AVI, and MOV.

The process involves loading a source video, deselecting all video, subtitle, and chapter tracks, selecting only the desired audio stream, and then "muxing" it out into a new file, typically as an MKA (Matroska Audio) file, which is a simple container for the untouched audio stream. This ensures a mathematically lossless pathway to extract audio from video on windows, as the original audio data is copied bit-for-bit without any re-encoding.

Pros

• Guarantees a perfectly lossless extraction via direct stream copying.
• Offers precise control to select and isolate specific audio tracks from files with multiple streams.
• Handles a wide variety of audio and video source container formats (MP4, AVI, MKV, etc.).
• Completely free, open-source, and well-maintained software.

Cons

• The interface is designed for multiplexing and can feel less intuitive for simple audio extraction.
• The default output format (MKA) is less universally compatible than MP3 or AAC, though the audio inside is untouched.
• The workflow can feel indirect for a single-purpose task, as it requires manually deselecting video/subtitle tracks.
