What is Sample Champion?
Accurate,
fast and powerful
Sample
Champion is an accurate and easy to use audio measurement
software. It has been designed for acoustical technicians,
sound engineers, scientists and students. With this
software you'll be able to easily perform Impulse
Response measurements, FFT analysis and much more.
Amazing
features
Some
very useful options are available, such as:
MLS pre-filtering (pink and/or custom spectrum)
synchronous
averaging
in time and frequency domain
double
precision FFT
real-time
results (the Impulse Response can be monitored
during the averaging process)
possibility
to calibrate the system using internal or external
sources.
Expandable
and versatile
Sample
Champion
has been
designed with special attention to the possibility
of future improvements and expansions. Special purpose
signal processing plug-ins are available and others
will be released.
Currently
available pugins:
Audio
Quality Plugin
SNR
(Signal to Noise Ratio)
THD
and THD+N
(Total
Harmonic distortion)
IMD
(Intermodulation Distortion)

Filter
Banks
This
module allows to approximate BUTTERWORTH
and CHEBYSHEV low-pass, band-pass and high-pass
analog filters by means of IIR (Infinite Impulse
Response) digital filters. Moreover two banks
of IEC 1260 Octave and 1/3 Octave
Filter Banks are implemented as presets. This
module can be used for filtering a measured or
loaded impulse response.

Waterfall
Plot
This
module computes and plots (see the below figure)
a 3D Cumulative Spectral Decay of an impulse
response. Many options are available, such as
different FFT sizes and weighting windows (independently
from the main program settings).

Room
Acoustics
This
module computes and plots many
acousical parameters, such as Reverberation
Time, Early Decay Time, Definition,
Clarity and Centre Time. Many options
and features are available: the acoustical parameters
can be computed in wideband or in octave or 1/3
octave bands. Results are available in tabular
or graphic form. Time data can be plotted in many
modes: Log Squared, Schroeder Plot, Step Response,
Cumulative Energy. Inverse Schroeder Integration
can take advantage of an user selectable noise
compensation. Computed data can be exported to
Clipboard and plots can be saved to disk as Bitmap
images.
