MP3, WAV, M4A, FLAC, OGG, Opus, AIFF, WMA, AMR and the sound of most videos. Files stay on your device.
How it works
- Choose an audio file.
- Set the pan position from -100 (left) to +100 (right).

Panning and balance
Pan position runs from −100 (hard left) to +100 (hard right). On a mono file the sound becomes stereo and is placed at that position. On a stereo file the control works as a balance: the side away from the position is turned down and the near side keeps its level, so the image shifts without changing what is already on each side.
Pan law
A mono sound in the centre plays from both speakers, so it sounds louder than the same sound played from one. A pan law compensates. Constant power (the default) puts the centre 3 dB down so loudness stays steady as the sound moves. Compromise is 4.5 dB down, linear is 6 dB down, and No pan law leaves the centre at full level with only the far side turned down. The page shows the gain it applies to the left and right.
Output
The result is a stereo file in the format you choose. Files with more than two channels are not supported. For a moving pan, use the 8D audio tool; for different settings per section, cut the file first.
Questions
How do I make a recording play only in the left ear?
Set the position to −100. On a mono file the sound plays only from the left; on a stereo file the right channel is turned off.
Which pan law should I use?
Constant power is the usual choice. Use No pan law if you want the centre to stay as loud as the original.
What happens on a stereo file?
The pan works as a balance control. The side opposite the position is turned down along the law’s curve; the near side keeps its level.
Can the pan change over time?
Not in this tool. The 8D audio tool moves the sound automatically.
