PLoS ONE 12(10):Įditor: Blake Johnson, Australian Research Council Centre of Excellence in Cognition and its Disorders, AUSTRALIA We also suggest that neurophysiological models of sound localization in animals could benefit from revision to include the influence of top-down memory and sensorimotor integration across head rotations.Ĭitation: Hambrook DA, Ilievski M, Mosadeghzad M, Tata M (2017) A Bayesian computational basis for auditory selective attention using head rotation and the interaural time-difference cue. Our findings suggest that an “active hearing” approach could be useful in robotic systems that operate in natural, noisy settings. Contrary to commonly held assumptions about sound localization, we show that the ITD cue used with high-frequency sound can provide accurate and unambiguous localization and resolution of competing sounds. The model makes use of head rotations to show that ITD information is sufficient to unambiguously resolve sound sources in both space and frequency. We present a simple Bayesian model and an implementation on a robot that uses ITD information recursively. This has been thought to limit their usefulness at frequencies above about 1khz in humans. The neural computations for detecting interaural time difference (ITD) have been well studied and have served as the inspiration for computational auditory scene analysis systems, however a crucial limitation of ITD models is that they produce ambiguous or “phantom” images in the scene. However, the ability of such systems to resolve distinct sound sources in both space and frequency remains limited. It is well-known that animals use binaural differences in arrival time and intensity at the two ears to find the arrival angle of sounds in the azimuthal plane, and this localization function has sometimes been considered sufficient to enable the un-mixing of complex scenes. Compression Disabled.The process of resolving mixtures of several sounds into their separate individual streams is known as auditory scene analysis and it remains a challenging task for computational systems.

Manual entries are not accepted.Īctive Users: 1 ( 1 guest, 0 members, 0 anonymous members )Īll times are GMT -5:00, Time now is 5:47pm The buffer size menu selection in "latency checker, global settings" (64 - 3072) does not contain the same selection in PowerSDR - Setup - Global (256 - 2048). In the register "advanced" -> "sample rate change restriction" there is a menu selection concerning different types of "clients: None, ASIO, All" What influence has this selection? I think some help in the "owner manual" would be very useful.

In "normal mode" they correspond to each other. I do not know, if this is of any importance. They do not conform with the menu selection in Power SDR - Setup - Audio - General. 1024 will change to 1152 in "safe mode" (i.e. Some combinations in the "latency checker, global settings" of sampling rate and buffersize are possible in "normal" mode whereas in"safe mode 1" you can not enter them.

Probably based on these values, the recommendation was "normal", but this did not work in my case. The CPU load during my experiments was always something between 8 to 25 %.

I my case, it showed values far below 100 us. Also the previously mentioned message showed up a few timesĬonclusion for me: the "latency checker" seems not as perfect as it should be. Each time, going back to "normal", the interruptions (during transmit, changing bands or moving the mouse) or the freezing occurred. I finally decided for "2048" buffer size and "96K" sampling rate.

Then I changed from "normal" to "save 1" mode and ups:, the software "Power SDR" worked perfectly well with different combinations of sampling rates and buffer sizes. I own a rather fast and modern computer which is basically dedicated to the SDR application.įirst I tried different combinations of "sampling rates" and "buffer sizes".

Than I started to experiment with "mode", "sampling rate" and "buffer size".Īccording to the "latency checker" which is part of the driver configuration, I can use "normal mode".

Second I updated from version 1.14 to version 1.16 including the firmware update 1.3.0.0 which also did not help.
