; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is

; and programs. Defaults to 1000.
; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of an USBRADIO
; channel. Two implementations are currenlty available - "fixed"
; (with size always equals to jbmax-size) and "adaptive" (with
; variable size, actually the new jb of IAX2). Defaults to fixed.
; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".

* The following parameters are used in the driver:
*
* FRAME_SIZE the size of an audio frame, in samples.
* 160 is used almost universally, so you should not change it.
*
* FRAGS the argument for the SETFRAGMENT ioctl.
* Overridden by the 'frags' parameter in usbradio.conf
*
* Bits 0-7 are the base-2 log of the device's block size,
* bits 16-31 are the number of blocks in the driver's queue.
* There are a lot of differences in the way this parameter
* is supported by different drivers, so you may need to
* experiment a bit with the value.
* A good default for linux is 30 blocks of 64 bytes, which
* results in 6 frames of 320 bytes (160 samples).
* FreeBSD works decently with blocks of 256 or 512 bytes,
* leaving the number unspecified.
* Note that this only refers to the device buffer size,
* this module will then try to keep the lenght of audio
* buffered within small constraints.
*
* QUEUE_SIZE The max number of blocks actually allowed in the device
* driver's buffer, irrespective of the available number.
* Overridden by the 'queuesize' parameter in usbradio.conf
*
* Should be >=2, and at most as large as the hw queue above
* (otherwise it will never be full).
