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.

-a[:]bits,channels,rate

With -s will return the format string as info, alone it will add it to the main display. (format)

If -s and -f are enabled with this the info printed will be the sample’s bitwidth. (bits)
