New Audiolense releases

whoareyou said:

@juicehifi - In my case, it's approaching a year since paying the extended support and upgrade fee.
Although there are no showstopper defects, it would have been nice to receive a program update addressing some of the issues / enhancements discussed over the course of that year.

Can you provide any information as to when your schedule will allow for releasing a program update?

I realize and appreciate that a product takes time and effort to support, but I would also like to receive some type of product improvements from time to time.
Thanks

I can understand why you’re asking. And I guess some progress reporting is due here.

The plan for the next release is direct resampling of correction filters and Atmos support.

This has not been the best year for Audiolense development with documented progress. About a year ago I was working on an API for the convolver to enable 3rd party GUI development. Unfortunately that work hasn’t surfaced yet. I need to do at least one more rotation. Then some of you guys may be able to make your own GUI. And then I have one or two GUI ideas in my own.

By the start of this year I was forced to abandon my old provider of accounting system and webstore, which took most of the available Audiolense time in the first half year. That job isn’t fully completed yet, but when I’m done I will have a very effective system for most of the paperwork associated with this small business … and I expect it to be that way for years to come. So there has been plenty of development there, just not on the software. When I’m done I will be able to spend most of the time on development and support, which is what I really want to spend time on.

This autumn I have also been very busy with my other job, so progress has been a bit slower than normal for this time of the year. But I have good hopes of getting the new release out by end of January.

Audiolense 6.22 is out

• New optional correction filter resampling. The time duration of the filter is kept intact on the resampling, so there will be no truncation of the low frequency correction. The frequency response is extended on upsampling, but frequency and time domain behavior is practically identical within the common bandwidth. The upsampling supports rates up to 5.6 million Hz. Upsampling to very high frequencies will be disabled when an upsampling will exceed the maximum filter-length, which is limited by the capacity of the math library used in Audiolense. The solution then is to shorten the filter length in the correction procecure designer until the desired sample rate is enabled.
• Added phase view, with wrapped and unwrapped phase.
• Modified draw charts functions to support phase switching.
• Removed delete rows in speaker setup since it caused unanticipated problems. The delete button gets the job done…
• Updated the help file, which now only comes as a PDF.

Mine are identical as before, but if you could send me the measurement file you were using here I will check this out.

Yes this doesn’t look right. I’ll give it a try tomorrow. If I don’t find it fast then, it may take a couple of weeks.

• A driver alignment error was unfortunately introduced in 6.22, which is fixed now.
• Fixed a bug related to manual speaker/driver delay entry.

I've put the same relase date on this, and 6.22 should not be used when digital crossovers are used.

Thank you @whoareyou and @sledwards for pointing out the problem.

I was trying to test out the new Resample Correction feature and am wondering what I may be doing wrong. When I select the output rate (96kHz or any other value), I get the error shown in the attached file.

Hi Steve,

You have stumbled over a bug. I am not able to reproduce it here. Could you be so kind and send me your measurement, target and all the correction details?

• Beta release. Consider it a beta release for now. I’ll remove this remark if it turns out all right.
• A peak-finding procedure had to be reworked to function properly with the new resampling. This procedure is widely used for speaker and crossover alignment, therefore the beta status for now.
• A small rounding error on the peak finder was discovered, the fix may lead to improved alignments in some setups.
• Detected a small target display error that was fixed.
• Disabled saving of frequency range in the charts, which has caused problems for users frequently.

They are probably a lot closer thann this. … but this view is a wrapped phase. In the unwrapped, the top will likely be faster since the high end has been extended.

Personally I mostly look at the time domain and frequency domain.

I am happy if the peak matches and the frequency domain looks clean. And regarding clean … I’ve spent more than a few weeks trying out various alternatives. The difference from before is most unlikely to be audible in most imstances, but in the long run technical quality will get the upper hand. If it does not improve sound quality for the majority, it may give a more predictably & excellent result for everybody. So I aim for technical perfection when I attach such issues, regardless of what I believe of the threshold of hearing and sonic impact short term.

It appears that the resampling wasn't complete yet...

• Beta release. Consider it a beta release for now. I’ll remove this remark if it turns out all right.
• Corrections for the native frequency was not saved for all correction formats. This has been fixed.
