NAME

ecalength - prints audio file length and other information

SYNOPSIS

ecalength [-ahtsfmbcr] FILE1 [FILE2] [FILEn]

DESCRIPTION

This is ecalength, a few lines of code pompously named so because they let one retrieve the length of an audio file from the command line using ecasound’s engine.

Limitations:

	- With files without header information (raw files), ecalength will only work correctly if the audio file is at a sampling rate of 44100 hz. (Addressed with the -a switch.)
	- It is not foolproof, feeding it with something other than an audio file WILL result in ugly things being spewed back. (A bit better)
	- A thousand more that I haven’t thought of.

OPTIONS

-h

Prints this usage message. (help)

-a[:]bits,channels,rate

Changes the format assumed by default for headerless data. (adjust)

	-t		Prints the summed length of all the files processed. (total) (Ignored if with -s)
	-s		Enables script mode: One info type per file per line. (script) (Defaults to length in secs.)
	-f		With -s will return the format string as info, alone it will add it to the main display. (format)
	-b		If -s and -f are enabled with this the info printed will be the sample’s bitwidth. (bits)
	-c		If -s and -f are enabled with this the info printed will be the channel count. (channel count)
	-r		If -s and -f are enabled with this the info printed will be the sampling rate. (rate)
	-m		Will print human computable time as in main display but in batch fashion. (minutes) (Only with -s)
