Too little information to really understand what you're doing, anyway:
A) to encode a supported source file (virtually all PCM audio formats including 8, 16, 24, and 32-bit ints; 32-bit floats; mono, stereo, and multichannel; sampling rates from 6 to 192 kHz and non-standard rates) it's sufficient for you to simply type:"wavpack" then the source file name separated by a space and hit enter
B) if you'd like to play with different compression options and decoding speeds refer to the official Usage Guide here: http://www.wavpack.com/wavpack_doc.html#usage
C) wavpack --help gives you the following:
WAVPACK Hybrid Lossless Audio Compressor Win32 Version 4.60.1
Copyright (c) 1998 - 2009 Conifer Software. All Rights Reserved.
Usage:
WAVPACK [-options] [@]infile[.wav]|- [[@]outfile[.wv]|outpath|-]
(default operation is lossless; infile may contain wildcards: ?,*)
Options:
-a Adobe Audition (CoolEdit) mode for 32-bit floats
-bn enable hybrid compression
n = 2.0 to 23.9 bits/sample, or
n = 24-9600 kbits/second (kbps)
add -c to create correction file (.wvc)
--blocksize=n specify block size in samples (max = 131072 and
min = 16 with --merge-blocks, otherwise 128)
-c hybrid lossless mode (use with -b to create
correction file (.wvc) in hybrid mode)
-cc maximum hybrid lossless compression (but degrades
decode speed and may result in lower quality)
--channel-order=<list> specify (comma separated) channel order if not
Microsoft standard (which is FL,FR,FC,LFE,BL,BR,
LC,FRC,BC,SL,SR,TC,TFL,TFC,TFR,TBL,TBC,TBR);
specify '...' to indicate that channels are not
assigned to specific speakers, or terminate list
with '...' to indicate that any channels beyond
those specified are unassigned
-d delete source file if successful (use with caution!)
-e create self-extracting executable with .exe
extension, requires wvself.exe in path
-f fast mode (faster encode and decode, but some
compromise in compression ratio)
-h high quality (better compression ratio, but slower
encode and decode than default mode)
-hh very high quality (best compression, but slowest
and NOT recommended for portable hardware use)
--help this extended help display
-i ignore length in wav header (no pipe output allowed)
-jn joint-stereo override (0 = left/right, 1 = mid/side)
-l run at lower priority for smoother multitasking
-m compute & store MD5 signature of raw audio data
--merge-blocks merge consecutive blocks with equal redundancy
(used with --blocksize option and is useful for
files generated by the lossyWAV program or
decoded HDCD files)
-n calculate average and peak quantization noise
(for hybrid mode only, reference fullscale sine)
--no-utf8-convert don't recode passed tags from local encoding to
UTF-8, assume they are in UTF-8 already.
--optimize-mono optimization for stereo files that are really mono
(result may be incompatible with older decoders)
-p practical float storage (also affects 32-bit
integers, no longer technically lossless)
--pair-unassigned-chans encode unassigned channels into stereo pairs
-q quiet (keep console output to a minimum)
-r generate a new RIFF wav header (removes any
extra chunk info from existing header)
--raw-pcm input data is raw pcm (44100 Hz, 16-bit, 2-ch)
--raw-pcm=sr,bps,ch input data is raw pcm with specified sample rate,
sample bit depth, and number of channels
(specify 32f for 32-bit floating point data)
-sn override default noise shaping where n is a float
value between -1.0 and 1.0; negative values move noise
lower in freq, positive values move noise higher
in freq, use '0' for no shaping (white noise)
-t copy input file's time stamp to output file(s)
--use-dns force use of dynamic noise shaping (hybrid mode only)
-w "Field=Value" write specified text metadata to APEv2 tag
-w "Field=@file.ext" write specified text metadata from file to APEv2
tag, normally used for embedded cuesheets and logs
(field names "Cuesheet" and "Log")
--write-binary-tag "Field=@file.ext"
write the specified binary metadata file to APEv2
tag, normally used for cover art with the specified
field name "Cover Art (Front)"
-x[n] extra encode processing (optional n = 1 to 6, 1=default)
-x1 to -x3 to choose best of predefined filters
-x4 to -x6 to generate custom filters (very slow!)
-y yes to all warnings (use with caution!)
