Sound Test Files | 1.0.3 | Download
DescriptionSome sound files in WMA format are included to help you calibrate your headphone, loudspeaker, headphone, Hi-Fi and related audio equipment.
To use the files, select it in a Media Player. Also select looping or repeating mode of playback. Then you can begin to play the sound file. Most players create an artificial silent time between repetitions. The ears can detect this easily. But the program can skip over the silent period if we choose the long-time average mode. For accurate frequency measurement, the narrow band analysis should be used. However, the wider shape of spectral peaks for wide band analysis makes peaks easy to identify and measure.
Normally, you will connect your earphone output to the audio equipment under test. Then you bring the pocket PC near the speaker of the system, and run a spectrum or spectrogram display program while the Media or MP3 Player is running in the background. Some Media Players any not be able to produce continuous sound even within the time span of the sound file, which cannot be used.
