Advanced Panning


The Acoustic Mirror plug-in allows you to use head-related transfer functions (HRTF) to apply advanced panning to your files.

Best results are achieved when using headphones and when the original file is monaural. You should first convert the file to a stereo format by replicating the mono channel to two tracks.

The TBD\HRTF folder includes a collection of impulse files containing directional cues. The files included are separated into Left and Right folders. The two numbers in each file name indicate the elevation (up or down) and azimuth (left or right) angles in degrees. For example:

File Name



Straight ahead


Far Left


Far Right


Completely above your head


Behind you


A bit below you, behind you, and to your left

Sound Forge Pro idea Advanced PanningTo create your own HRTF impulse files, use a dummy head with a microphone in each ear. Rotating a loudspeaker around the dummy head and create different impulse response files for various loudspeaker locations.
