    Issue with Mac

    Hi everyone, I recently switched to Mac and today I installed REW to do some measurements. However, I am unable to do them due to the following problem. When I start the sweep measurement, the signal takes a long time to be emitted from the speakers, and before it finishes the software has...

    Help to obtain pre-ringing measurement

    Ok, I understand what you mean. We were talking about two different things though. You talk about the capture stream, while I talk about the playback stream. The behavior I've seen, that REW does the resample, is with playback. In fact in this case if REW and OS sample rate differ, it turns out...

    Help to obtain pre-ringing measurement

    Thanks for the clarification. I managed to make the measurement that I had to. I am not sure about this. I tried to monitor what REW transmit to the driver using API Monitor, following this instruction. With REW set to 44.1kHz and WASAPI Shared output, and output device set to 192kHz from...

    Help to obtain pre-ringing measurement

    SORRY, I must be ignorant... how do I get that graph with REW? I can play only sweeps...

    Help to obtain pre-ringing measurement

    Ok, thanks for the feedback. I accidentally removed previous image, but reuploaded it with the same measurement... However, why that comb effect is displayed? Shouldn't it be a continuous line, at most with a sinusoidal trend? I applied Tukey window then to perform other measurements, but...

    Help to obtain pre-ringing measurement

    Sure, attached. Here how it looks to me... NOTE: no room correction filter applied in this measurement. I expect to see perfect step... But... REW sample rate is set to 44.1 and loopback audio device at 192, so upsampling maybe happen somewhere... it's REW that upsample to match driver sample...

    Help to obtain pre-ringing measurement

    Hi all, I'm trying to make an impulse measurement on my sound card's digital loopback to see how the pre-ringing of a room correction filter develops. I play a full range sweep and then record the signal with digital loopback. If I'm not mistaken I should see it with the step response. But...

    Speaker compression linearization

    Hello everyone, I open this thread to ask if it is possible to develop an additional correction function in Audiolense, combined with its convolver. Measurements of audio equipment are now fashionable and many people are specializing in this, offering ever more comprehensive measurements. Among...

    Question about time domain correction

    Thanks for your reply. I am reading a bit of information material, and often the early reflections, especially horizontal, are considered benign as they help to broaden the sound stage. At least in the mid and high range. That's why I wanted to experiment. But at this point I have to ask, what...

    Question about time domain correction

    Hi everyone, I would like to experiment a bit with Audiolense filters to better understand the subjective effects of time corrections. In this sense I would like to create a correction for my 2.2 system that linearises frequency, phase and aligns the speakers, but which does not intervene on the...

    Time alignment of drivers

    Thanks Bernt, almost clear. What exactly does the bold phrase mean?

    Can't set low pass XO value

    Also in the speaker tab I have the same problem. Any value I type, then it disappears.

    Time alignment of drivers

    I'm trying to figure out the best solution to adopt for my multi-way system. From the Audiolense XO demo I saw that the software takes care of aligning the drivers, however I would like to understand better which method it uses. In particular I would like to understand if the alignment is based...

    Can't set low pass XO value

    Yeah... but I want to low pass a subwoofer. And I can't set the value

    Can't set low pass XO value

    (I take a screenshot from the web for convenience, it is not my capture) The value I am referring to is the one in the Low Pass column. In my case the column is empty, and if I write a value to it, when I exit with the cursor it disappears.
