Octave and one-third octave band measurements with NTi’s FX100

NTi Audio provides a tool to derive octave and one-third octave band results from FFT measurement results using the FX100 Audio analyzer, as required by audio applications where standards require octave or one-third octave band measurements.

As the Speech Transmission Index for Public Address Systems (STIPA) now enters its second decade, NTi Audio reflects on the early years and how the process evolved through active interaction with international standards committees. Meanwhile, NTi Audio has released the Wave File Converter, a free PC software that allows creating custom files for playback through NTi Audio signal generators.
