This initial system release is made in order to encourage discussion and development of the system.

Although a basic framework design has been created this is only a starting point and architecture may change if requirements change.

Any input, ideas, code, suggestions, information resources, etc.. you may have please email: soundproofing@gmail.com

command line options:

        -p              process
        -c #            channels
        -d #            Sample bits
        -i              infile
`       -o              outfile
        -l #            length in seconds
        -r #            Sample rate
        -s <c|l|m>      source
                        c = cd; l = line; m = mic

How to Calibrate the SPL Meter.

There are two types of calibration that can be used a simple high and low level calibration and a full response table.

• Connect calibrator. Connect an SPL calibrator to the microphone mount, or, if none is available, use a high quality SPL meter and the pink noise generator. Either way, generate a known SPL field.
• use command line: "wavc -l n" where n is the the SPL that is being generated
• use command line: "wavc -h n" where n is the the SPL that is being generated

The above steps will create a very basic two level calibration but due to the response of some microphone transducers you may want to create a full range correction. This can be achieved by use of the command : "wavf -l n" where n is the calibration SPL, this can be repeated for any number of levels to create a full calibration table. The calibration table is saved in a file calib.txt.
