which is approximately on the axis of the instrument. The radiation from the french
horn is strongly dependent on frequency, but consistently biased towards negative
elevations and positive azimuth angles greater than 90 ◦ . This type of information is
useful in determining the optimum microphone placements for recording sessions.
It is also valuable in guiding the design and construction of loudspeaker arrays
with directivities matching those of the instruments which they replicate in virtual
