Extract Audio from Video

Extracting audio from video files is essential for content creators, educators, and anyone who needs to isolate sound for repurposing or editing. This tool pulls the audio track directly from video files and saves it as a high-quality WAV file, all within your ブラウザ without any file アップロードs to external servers.

Common 使用例

Whether you're working with podcasts, tutorials, music videos, or conference recordings, extracting audio is incredibly useful. Musicians use it to work with instrumental tracks or remixes, podcasters extract background music from intro videos, educators isolate lectures from recorded classroom sessions, and content creators repurpose audio across different projects. You might also need to preserve audio from a video file before 変換ing it to a different フォーマット.

Key 機能

This tool supports multiple video フォーマットs including MP4, WebM, and MOV, handling various codec combinations. The extraction uses the ブラウザ's Web Audio API, which means your video never leaves your デバイス—everything is processed locally. You get detailed technical inフォーマットion about the extracted audio, including the exact sample rate (measured in Hz), channel configuration (mono or stereo), duration, and total sample count. This lets you verify the quality before ダウンロードing.

Why WAV フォーマット

WAV (Waveform Audio フォーマット) is un圧縮ed and lossless, preserving every bit of audio quality from the original video. Unlike MP3, WAV doesn't throw away audio inフォーマットion, making it perfect for further editing, mixing, or analysis. The extracted audio is saved as 16-bit PCM WAV, which is compatible with virtually every audio editing software including Audacity, Adobe Audition, and DaVinci Resolve.

Workflow

Simply select your video file, wait for extraction to complete, preview the audio instantly in your ブラウザ, and ダウンロード the WAV file. You can view audio metadata before ダウンロードing and verify it's exactly what you need.
