I'll be checking in code for a new option tonight. Using --sector-align when encoding a group of WAVE files will cause the encoder to align each file to a CD sector boundary before encoding. A CD sector is 588 samples and the option only works for WAVE data with a sample rate of 44100 Hz and 2 channels. The alignment is always backwards from the original breakpoint. In other words, if the first file does not end on a sector boundary, the last partial sector will be carried over to the encoding of the next file. The same thing is done to the next file, up until the last file. If the last file is not aligned it will be padded to alignment with zeroes. Here's an example output: bash-2.01$ flac -0 -V --sector-align s[1234].wav flac 1.0devel, Copyright (C) 2000,2001 Josh Coalson flac comes with ABSOLUTELY NO WARRANTY.
