SoxJSONStatStats

Personal fork of the 'stat' and 'stats' effects in SoX. Provides an additional option for JSON output (prints to stderr.) If you're tired of parsing the output of SoX with grep and would rather use JSON, compile SoX with these two files. The 'stats' effect is generally more useful, and provides information about each channel in a multi-channel file. To use, just add a '--json' flag after you call stat or stats, like this:

$ sox somefile.wav -n stat --json

{
	"samplesRead" : "657090",
	"lengthInSeconds" : "14.900000",
	"scaledBy" : "2147483647.000000",
	"maximumAmplitude" : "0.434052",
	"minimumAmplitude" : "-0.528595",
	"midlineAmplitude" : "-0.047272",
	"meanNorm" : "0.044004",
	"meanAmplitude" : "-0.000000",
	"RMSAmplitude" : "0.074119",
	"maximumDelta" : "0.171356",
	"minimumDelta" : "0.000000",
	"meanDelta" : "0.004453",
	"RMSDelta" : "0.009420",
	"roughFrequency" : "891",
	"volumeAdjustment" : "1.891808"
}
