Sample Champion is a powerful real-time software tool
designed for high precision acoustic measurements.
With Sample Champion you will be able to measure the
Impulse Response of a room, or analyze loudspeaker
Frequency Responses using the MLS (Maximum Length
Sequence) method. It has been designed for acoustical
technicians, sound engineers, scientists and students.
Sampling rate 5 kHz up to 192 kHz, 2 channels, 24 bit
support. FFT length up to 64K points.
