I have to do a long term meeting of soundlevels. I use a condenser microphone and a cheap soundmeter. My plan is frpm one speaker 1 meter from the microphones send sine waves and place the sound meter beside the microphone. Record the sound then adjust the line in level so the in-signal is the same as measuered on the soundmeter. The results from the following measuremt will be 1 minute long wav files and a plot from the file. I plan to record the files once each ten minutes. So : How do I compare data from recorded files and calculate the correct decibel-levels.? And why I not use a better sound-meter plugged in to the computer, it is becasue they all have to bad range in frequenzy.. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
