ecalength - prints audio file length and other information
ecalength [-ahtsfmbcr] FILE1 [FILE2] [FILEn]
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.
-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)
