Save audio from short clips
Extract speech, music, or ambient sound from a local MP4 or WebM clip.
What you get: The user gets the speech, music, or ambient sound from a local video as a separate audio file.
Extract Audio From Video Without Uploading
Extract audio from a local video clip.
Local processing · your file stays on your device
MP3, WAV, AIFF and AU use a fast local decode/export path when your browser can decode the video. WebM, OGG and M4A use a real-time local recording fallback, so a 3-minute clip takes about 3 minutes. Unsupported video codecs cannot be extracted in a browser.

| Video decoding | Choose a video | The video and its audio track must be playable by this browser before audio can be extracted locally. |
How to use
Get a cleaner result in four steps.
- Step 1 Load the local video clip
Choose an MP4, MOV, WebM, M4V, or other browser-decodable video where you only need the speech, music, or narration.
- Step 2 Set the start and end range
Extract the full video audio or enter a shorter section when you only need one speech segment, song, or presentation clip.
- Step 3 Choose the audio output
Pick MP3 for lightweight sharing or WAV when the extracted audio will be edited, cleaned, or transcribed.
- Step 4 Download and use the audio-only file
Click Extract and download audio, then send the new audio file to transcription, cleanup, archiving, or another Cinch tool.
Where it helps
When this tool helps.
Extract speech for transcription
Turn a short video recording into an audio-only file before sending it to a transcript workflow.
What you get: A video's spoken content becomes an audio-only file that is easier to send through a transcript workflow.
Reuse presentation audio
Pull narration from a screen recording so it can be cleaned or archived separately.
What you get: Narration from a screen recording can be cleaned, edited, or archived without keeping a duplicate video file.
Create lightweight references
Keep the audio from a video without storing the full video file in every project folder.
What you get: The project folder can keep a smaller audio reference instead of storing the full video in every place.
Best-in-class benchmark
What this page makes clearer.
Checked against mature online audio tools for the same job: the goal is not only to complete the task, but to make the next decision obvious.
The strongest converters cover practical source types, make compatibility tradeoffs visible, protect the original file, and help users choose the right export target.
Simple converters usually stop at file output and do not explain device compatibility, naming, hidden files, or follow-up cleanup.
Cinch adds compatibility context, safe-copy behavior, device-specific guidance, and workflow outputs like fix lists or editor-ready files.
FAQ
Questions before using this tool.
When should I use this browser-based audio tool?
Use it when you already have an audio file and need a cleaner, smaller, clearer, or easier-to-share copy before opening a full audio editor. It is useful for lecture recordings, meeting audio, voice notes, podcasts, music clips, MP3 files, WAV files, and saved browser recordings.
Does the audio file stay on my device?
Yes. This browser-based audio tool is designed to process the file locally, so you can test settings, preview the result, and download a new copy without uploading private recordings to a server.
Which audio formats work best?
Common browser-supported formats such as MP3, WAV, M4A, AAC, OGG, and FLAC usually work best. Very large files, unusual codecs, or protected streaming files may need to be converted, trimmed, or recorded again first.
What should I check before downloading the new audio?
Preview the result, compare it with the original, and make sure the speech, music, timing, volume, file size, or metadata still feels right. If the setting is too strong, choose a gentler option and run the audio processing step again.
