Create an splMeter to measure the octave sound pressure level of the audio file. Use the default calibration factor of 1. Create a dsp.ArrayPlot object to visualize the equivalent-continuous SPL for each octave band. Get. source = dsp.AudioFileReader( 'JetAirplane-16-11p025-mono-16secs.wav' ); fs = source.SampleRate;The Impulse time weighting is about four times faster than Fast, with a short rising time constant but a slow falling one. It is little used in most countries these days and so can usually be ignored. Fast corresponds to a 125 ms time constant. Slow corresponds to a 1 second time constant.
