NAME

ecalength - prints audio file lenght 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)
