Audio Channel Extractor
Take one channel from a stereo recording and save it as a mono WAV. Keep the left or right side without blending it with the other channel.
- Choose the left or right source channel
- Export the selected side as mono
- Avoid averaging unwanted channel content
Choose the useful side
A split interview may place each microphone on a different channel. Select the side containing the speaker or source you need.
Listen before saving
Left and right labels do not describe content quality. Preview each option when you are unsure which channel contains the clean recording.
Keep extraction separate from separation
The tool selects an existing channel. It cannot isolate vocals or instruments already mixed together within that channel.
Handle mono sources
A mono file has only one channel. Either side selection returns that same available signal rather than creating a new channel.

Audio Channel Extractor FAQs
Only if the unwanted material is entirely on the other channel. It is not source separation.
The exported result is mono, not a stereo file with one silent side.
Yes, if the speakers are actually recorded on separate channels. Choose left or right and export the wanted side as mono. If both voices are mixed into the same channel, this tool cannot separate them by identity or remove an overlapping speaker.
Audio Channel Extractor schedules a background render after a setting changes. The completed preview or analysis replaces the previous result automatically. Processing time depends on recording length and device performance; the status message shows when the new result is ready.
