Following some further fine-tuning of the method it's time to issue the next Release Candidate for lossyWAV:
lossyWAV v0.9.2 RC3, Copyright (C) 2007,2008 Nick Currie.
lossyWAV is issued with NO WARRANTY WHATSOEVER and is free software.
Usage : lossyWAV <input wav file> <options>
Example : lossyWAV musicfile.wav
Quality Options:
-1/1a/1b quality preset 1, circa 480kbps for 44.1khz, 2ch;
-2/2a/2b/2c quality preset 2, circa 425kbps for 44.1khz, 2ch [default];
-3/3a/3b/3c quality preset 3, circa 375kbps for 44.1khz, 2ch;
-4/4a/4b/4c quality preset 4, circa 350kbps for 44.1khz, 2ch;
-5/5a/5b/5c quality preset 5, circa 335kbps for 44.1khz, 2ch;
-6/6a/6b/6c quality preset 6, circa 320kbps for 44.1khz, 2ch;
-7/7a/7b/7c quality preset 7, circa 305kbps for 44.1khz, 2ch;
[a/b/c = 1/2/3 extra FFT analyses; default=3,2,2,2,2,2,2(max=5)]
Standard Options:
-o <folder> destination folder for the output file(s).
-nts <n> set noise_threshold_shift to n dB (-48.0dB<=n<=+36.0dB);
(-ve values reduce bits to remove, +ve values increase).
-snr <n> set minimum average signal to added noise ratio to n dB;
(0.0dB<=n<=48.0dB) Increasing value reduces bits to remove.
-force forcibly over-write output file if it exists; default=off.
-check check if WAV file has already been processed; default=off.
errorlevel=16 if already processed, 0 if not.
-noclips set allowable number of clips per channel per codec block to 0;
default= -1=0,-2=1,-3=2,-4=3,-5=4,-6=5,-7=6.
-correction write correction file while processing WAV file; default=off.
-merge merge existing lossy.wav and lwcdf.wav files.
-scale <n> scaling factor from WaveGain / etc; default = 1.000000.
System Options:
-quiet significantly reduce screen output.
-nowarn suppress lossyWAV warnings.
-detail enable detailed output mode
-below set process priority to below normal.
-low set process priority to low.
Special thanks:
David Robinson for the method itself and motivation to implement it.
Don Cross for the original Pascal source for the FFT algorithm used.
Horst Albrecht for valuable tuning input and feedback.
