236 * Revision 1.7 2006/02/25 00:53:48 egouvea
237 * Added the flag "-seed". If dither is being used and the seed is less
238 * than zero, the random number generator is initialized with time(). If
239 * it is at least zero, it's initialized with the provided seed. This way
240 * we have the benefit of having dither, and the benefit of being
241 * repeatable.
242 *
243 * This is consistent with what sphinx3 does. Well, almost. The random
244 * number generator is still what the compiler provides.
245 *
246 * Also, moved fe_init_params to fe_interface.c, so one can initialize a
247 * variable of type param_t with meaningful values.
248 *
249 * Revision 1.6 2006/02/17 00:31:34 egouvea
250 * Removed switch -melwarp. Changed the default for window length to
251 * 0.025625 from 0.256 (so that a window at 16kHz sampling rate has
252 * exactly 410 samples). Cleaned up include's. Replaced some E_FATAL()
253 * with E_WARN() and return.
254 *
255 * Revision 1.5 2006/02/16 00:18:26 egouvea
256 * Implemented flexible warping function. The user can specify at run
257 * time which of several shapes they want to use. Currently implemented
258 * are an affine function (y = ax + b), an inverse linear (y = a/x) and a
259 * piecewise linear (y = ax, up to a frequency F, and then it "breaks" so
260 * Nyquist frequency matches in both scales.
261 *
262 * Added two switches, -warp_type and -warp_params. The first specifies
263 * the type, which valid values:
264 *
265 * -inverse or inverse_linear
266 * -linear or affine
267 * -piecewise or piecewise_linear
268 *
269 * The inverse_linear is the same as implemented by EHT. The -mel_warp
270 * switch was kept for compatibility (maybe remove it in the
271 * future?). The code is compatible with EHT's changes: cepstra created
272 * from code after his changes should be the same as now. Scripts that
273 * worked with his changes should work now without changes. Tested a few
274 * cases, same results.
275 *
276 * Revision 1.4 2006/02/14 20:56:54 eht
277 * Implement an argument -melwarp that changes the standard mel-scale
278 * equation from:
279 * M(f) = 2595 * log10( 1 + f/700 )
280 * to:
281 * M(f,w) = 2595 * log10( 1 + f/(700*w))
282 *
283 * So, 1.0 means no warp, w > 1.0 means linear compression w < 1.0 means
284 * linear expansion.
285 *
286 * Implement argument -nskip and -runlen arguments so that a subset of the
287 * utterances in the control file can be executed. Allows a simple
288 * distribution of wave2feat processing over N processors.
289 *
290 * Revision 1.3 2005/05/19 21:21:55 egouvea
291 * Bug #1176394: example bug
292 *
293 * Revision 1.2 2004/11/23 04:14:06 egouvea
294 * Fixed bug in cmd_ln.c in which a wrong boolean argument led into an
295 * infinite loop, and fixed the help and example strings, getting rid of
296 * spaces, so that the appearance is better.
297 *
298 * Revision 1.1 2004/09/09 17:59:30 egouvea
299 * Adding missing files to wave2feat
