Description:

• The Speech Level Measuring program, SAM_SLM, has been developed in order to determine the speech level of a signal file. The method implemented for measurement of the signal level is based on a level distribution histogram of a squaring and lowpass filtering of the signal waveform, and the RMS value is calculated from this histogram. In addition the program permits the user to determine the DC offset of the signal file, too.
• The program is self explaining, i.e. invoking the program without parameters results a display of usage. Even though SLM stands for Speech Level Measurement the program can be used to determine the levels of noise files as well.
