195 ; resynchronized. Useful to improve the quality of the voice, with
196 ; big jumps in/broken timestamps, usualy sent from exotic devices
197 ; and programs. Defaults to 1000.
199 ; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of an USBRADIO
200 ; channel. Two implementations are currenlty available - "fixed"
201 ; (with size always equals to jbmax-size) and "adaptive" (with
202 ; variable size, actually the new jb of IAX2). Defaults to fixed.
204 ; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".

213 * Helper macros to parse config arguments. They will go in a common
214 * header file if their usage is globally accepted. In the meantime,
215 * we define them here. Typical usage is as below.
216 * Remember to open a block right before M_START (as it declares
217 * some variables) and use the M_* macros WITHOUT A SEMICOLON:
220 * M_START(v->name, v->value)
222 * M_BOOL("dothis", x->flag1)
223 * M_STR("name", x->somestring)
224 * M_F("bar", some_c_code)
225 * M_END(some_final_statement)
226 * ... other code in the block
229 * XXX NOTE these macros should NOT be replicated in other parts of asterisk.
230 * Likely we will come up with a better way of doing config file parsing.
232 #define M_START(var, val) \
233 char *__s = var; char *__val = val;
235 #define M_F(tag, f) if (!strcasecmp((__s), tag)) { f; } else
236 #define M_BOOL(tag, dst) M_F(tag, (dst) = ast_true(__val) )
237 #define M_UINT(tag, dst) M_F(tag, (dst) = strtoul(__val, NULL, 0) )
238 #define M_STR(tag, dst) M_F(tag, ast_copy_string(dst, __val, sizeof(dst)))
241 * The following parameters are used in the driver:
243 * FRAME_SIZE the size of an audio frame, in samples.
244 * 160 is used almost universally, so you should not change it.
246 * FRAGS the argument for the SETFRAGMENT ioctl.
247 * Overridden by the 'frags' parameter in usbradio.conf
249 * Bits 0-7 are the base-2 log of the device's block size,
250 * bits 16-31 are the number of blocks in the driver's queue.
251 * There are a lot of differences in the way this parameter
252 * is supported by different drivers, so you may need to
253 * experiment a bit with the value.
254 * A good default for linux is 30 blocks of 64 bytes, which
255 * results in 6 frames of 320 bytes (160 samples).
256 * FreeBSD works decently with blocks of 256 or 512 bytes,
257 * leaving the number unspecified.
258 * Note that this only refers to the device buffer size,
259 * this module will then try to keep the lenght of audio
260 * buffered within small constraints.
262 * QUEUE_SIZE The max number of blocks actually allowed in the device
263 * driver's buffer, irrespective of the available number.
264 * Overridden by the 'queuesize' parameter in usbradio.conf
266 * Should be >=2, and at most as large as the hw queue above
267 * (otherwise it will never be full).
