Audio sequence is broken into parts which contain only noise ("gaps"),
and parts with usable signal ("tracks").
The following configuration settings (and defaults) are supported:
frequency => 44100,__# If 'raw_pcm' or 'override_header_info' only
bytes_per_sample => 4,_# likewise
channels => 2,__# likewise
sizedata => MY_INF,__# likewise (how many bytes of PCM to read)
out_fh => \*STDOUT,__# mirror WAV/PCM to this FH if 'filter'
preprocess => {mp3 => [[qw(lame --silent --decode)], [], ['-']]}, # Second contains extra args to read stdin
rms_extension => '.rms',_# Appended to the 'filestem'
sec_per_chunk => 0.1,_# The window for taking mean square
threshold_in_sorted_min_rel => 0,_ # relative position of 'threashold_min'
threshold_in_sorted_min_sec => 1,_ # shifted by this amount in the list
threshold_factor_min => 1,__ # the list elt is multiplied by this
threshold_in_sorted_max_rel => 0.5,  # likewise
threshold_in_sorted_max_sec => 0,_ # likewise
threshold_factor_max => 1,  _ # likewise
threshold_ratio => 0.15,__ # relative position between min/max
above_thres_window => 11,__ # in units of chunks
above_thres_window_rel => 0.25, _ # fractions of chunks above threshold
_____ # in a window to make chunk signal
max_tracks => 9999,___ # fail if more signal/noise runs
min_signal_sec => 5,__ # such runs of signal are forced
min_silence_sec => 2,__ # likewise
ignore_signal_sec => 1,__ # short runs of signal are ignored
min_silence_chunks_merge (see below) # and long resulting runs of silence
_____ # are forced
local_level_ignore_pre_sec => 0.3,_ # offset the start of this interval
local_level_ignore_pre_rel => 0.02,  # additional relative offset
local_level_ignore_post_sec => 0.3,  # likewise for end of the interval
local_level_ignore_post_rel => 0.02, # likewise
local_threshold_factor => 1.05,
extend_track_end_sec => 0.5,_ # Unconditional enlargement
extend_track_begin_sec => 0.3,_ # likewise
min_boundary_silence_sec => 0.2,_ # Ignore short silence at start/end
Note that `above_thres_window' is the only value specified directly in
units of chunks; the other `*_sec' may be optionally specified in units
of chunks by setting the corresponding `*_chunks' value.  Note also that
this window should better be decreased if minimal allowed silence length
parameters are decreased.
These values are mirrored from other values if not explicitly specified:
min_actual_silence_sec << min_silence_sec__# Ignore short gaps
min_start_silence_sec  << min_boundary_silence_sec_# Same at start
min_end_silence_sec    << min_boundary_silence_sec_# Same at end
min_silence_chunks_merge << min_silence_chunks__# See above
cache_rms_write <<< cache_rms_  # Boolean: write RMS cache
cache_rms_read  <<< cache_rms_  # Boolean: read RMS cache (unless 'filter')
The following values default to `undef':
filename___# if undef, read data from STDIN
stem_strip_extension_# Boolean: 'filestem' has no extension
filter___# If true, PCM data is mirrored to out_fh
rms_filename__# Specify cache file explicitly
raw_pcm___# The input has no WAV header
override_header_info_# The user specified values override WAV header
cache_rms___# Use cache file (see *_write, *_read above)
skip_medians__# Boolean: do not calculate 3-medians
subchunk_size__# Optimization of calculation of RMS; the
____# best value depends on the processor cache
