HAL1x Latency Details

Ah, the classic “Latency” question. How much time does it take audio signals to travel from a given input to a given output? Keep in mind that, generally, latency only really matters when a reinforced acoustic source also exits a nearby loudspeaker. This got quite long. But it’s complete…

 

HAL4 latency is 2.2 milliseconds. See the HAL System Data All Specifications, page 50.
HAL3s is 2.39 milliseconds – analog input to analog output, see page 49.
HAL2 is 2.39 milliseconds – analog input to analog output, see page 46.

 

The rest of this discussion is about Latency in the HAL1x and its various Expansion (EXP) and RAD devices:

 

In the HAL System Data, page 6 there is a Latency drawing (below) that shows the different latencies depending on the physical path the audio takes, input to output (almost always through the DSP Core in the HAL1x).

Example #1:  HAL1x analog input (through the DSP Core) out to the HAL1x analog output is one path:

Rane ships new Halogen 4.0, EXP7x & HAL4 on HALloween

I know, you were sad that you missed my PowerPoint presentation at Rane’s InfoComm Booth in Orlando a few weeks ago because you had to golf. Or was it Disney World, or drinks with your industry pals? Or was it because your boss sent those other co-workers from the Sydney office?

Either way, don’t fret. I recorded the PowerPoint presentation without the convention center background noise. Continue reading

Need One Cable Through Multiple Conference Rooms with an AEC Mic Mixer Under Each Table? We’ve Got That.

Easy Audio ConferencingOver and over again, customers interested in Rane’s EXP7x Acoustic Echo Canceller (AEC) for the HAL1x asked for this solution. Their problem is, there’s no way – conduit or otherwise – to get the ten mics and two lines in each of several conference rooms to an AEC and the interconnect for VoIP, video codecs (remember those?), control systems, et cetera. Enter the HAL1x approach below. Continue reading

HAL videos from InfoComm 2013

Here are two short impromptu videos from the InfoComm 2013 show floor.

The first quickly reviews the four HAL products – the HAL1 through HAL4.

HAL Evolves at InfoComm – Video #1

The second video gives a brief overview of the HAL1x’s four EXP expansion devices – the newest is the EXP7x acoustic echo canceller. It also reviews the new Web Controls feature for any HAL device. (Boy, I sure sound nervous – I had to “wing it” and without a script or the makeup department!)

HAL Evolves even more at InfoComm – Video #2
