There is a one-to-one relationship between the panning coefficient of the sources and the derived panning index. A frequency-domain, time-varying panning index function is computed based on the cross-correlations of the left and right short-time FFT pair.

The algorithm is based on the comparison of the short-time Fourier Transforms of the right and left channels of the stereo mix. The source separation algorithm is implemented in the 'Compute Panning Index Function' subsystem. You may vary the panning coefficient of the speech source by double-clicking the Panned Source subsystem and modifying the position of the 'Panning Index' knob. The train whistle source is panned with a constant panning coefficient of 0.2. The model audiosourceseparation implements the panned audio source separation example. The example uses a frequency-domain technique based on short-time FFT analysis to identify and separate the sources based on their different panning coefficients. The stereo signal is a mix of two independently panned audio sources: The first source is a man counting from one to ten, and the second source is a toy train whistle. This example showcases a source separation algorithm applied to an audio stereo signal.

5.1 or 7.1) upmix, where the different extracted sources may be distributed across the channels of the new mix. It also plays a role in stereo-to-multichannel (e.g. Source separation has many applications, such as speech enhancement, sampling of musical sounds for electronic music composition, and real-time speech separation. Source separation consists of the identification and extraction of individual audio sources from a stereo mix recording. An artificial position or direction relative to the listener may be generated by varying the level of panning. At the 12 o'clock position, the sound is equally distributed across the two speakers. Conversely, when a signal is panned to the 4 o'clock position, the sound only appears in the right speaker. When a signal is panned to the 8 o'clock position, the sound only appears in the left channel (or speaker). Panning is usually controlled by a physical or virtual control knob that may be placed anywhere from the 'hard-left' position (usually referred to as 8 o'clock) to the hard-right position (4 o'clock). In studio stereo recordings, different sources or tracks (corresponding to different musical instruments, voices, and other sound sources) are often recorded separately and then mixed into a stereo signal. Panning is an essential component of sound engineering and stereo mixing. Panning can simulate the spatial perspective of the listener by varying the amplitude or power level of the original source across the new audio channels.

Panning is a technique used to spread a mono or stereo sound signal into a new stereo or multi-channel sound signal.
