Ich fand dieses Audiomess-Prg sehr intressant.
MacSpeaker is a program which handles measurements in the audio range, above all, loudspeaker measurements.
MacSpeaker makes use of the Macintosh sound hardware
so that you do not need an expensive Analog-Digital conversion card.
You only need a measuring microphone and perhaps a microphone amplifier.
You will get a professional measuring system at a fraction of the price of comparable systems!
Because the Macintosh has excellent sound hardware, the measurement accuracy of
MacSpeaker is comparable to professional systems: 44.1 kHz 16-bit sampling; that is, CD quality.
MacSpeaker controls all important loudspeaker measurements:
From the measurement of the impulse response, a Fourier transform
computes the frequency response of the loudspeaker (absolute and phase).
zu finden z.b. auf dem www.Shareware.com Server unter Mac.
