Fix One-Ear Audio

Using the Fix One-Ear Audio

Fix a recording whose useful audio is on only one side, swap reversed channels, or reduce an uneven left-right balance. Listen to the original and check the channel readings before choosing a fix.

Instructions

1. Choose an audio file or drop it into the tool. The demo lets you try a recording with sound on one side.
2. Read the left and right level readings and the suggested action. Play Original to confirm which side contains the audio you want.
3. Choose Left to both ears or Right to both ears for a one-sided recording. Use Swap for reversed sides, Mono to mix both channels, or Balance to reduce either side independently.
4. Apply your fix, preview the output, then download the WAV. Apply again after changing the mode or balance settings.

What each channel fix preserves

Copying one side to both ears creates a stereo file with the same audio on the left and right; audio from the other side is discarded. Swap exchanges the channels. Mono averages them into a single channel, while Balance reduces their levels independently without boosting either side. The exported file is a 24-bit WAV at the decoded sample rate.

What to do if you still hear sound in one ear

• A mono source should already play through both ears. If other recordings also sound one-sided, check your headphones, cable and device balance settings.
• If both channels are silent, copying a channel cannot restore missing audio. Check the source recording before applying a fix.
• If mixing to mono makes the sound much quieter, the channels may cancel. Copy the useful side instead, and preview before downloading.

Files are processed locally. Retain the original, especially when the channels contain different microphones or instruments that you may want to edit separately later.
